1. PURPOSE

This Standard provides appearance specifications for cosmetic parts comprising Sony commercial products, as well as acceptance criteria for visual inspection. Especially, Appearance Grades to be verified using the specified Dot G auge allow us to conduct an objective and quantitative evaluation for cosmetic surfaces.

This Standard aims to standardize appropriate requirements and inspection criteria for cosmetic surfaces company-wide, minimizing differences in evaluation results among receiving divisions, design divisions, and suppliers in a unified manner.

2. SCOPE

This Standard applies to cosmetic parts made of plastics, metals, or steel sheets, to which surface treatment

(e.g., painting, printing, foil stamping, and plating) is applied, surface-treated steel sheets, or plastics whose

surfaces are not finished.

3. PRAC

T ICAL RULES

The designer shall describe appearance specifications for the cosmetic parts on the drawing with reference

to the visual inspection criteria detailed hereinafter. See Table 3.1 for advantages and disadvantages of

each of the criteria. It is recommended that the designer adopt Appearance G rades so as to perform a

quantitative evaluation from an objective standpoint. Instructions for appearance specifications shall be

given in accordance with the procedures shown in Figure 3.1.

Table 3.1 Advantages and disadvantages of each visual inspection criterion

Inspection

criteria

Advantages Disadvantages

Appearance Grades Enable an objective and quantitative

evaluation, using the Dot Gauge, to minimize

differences in evaluation results among design

divisions, receiving divisions, and suppliers.

Make it difficult to evaluate some types of defects

on surfaces (e.g., hue and crack depth).

Boundary samples Allow design divisions to provide receiving

divisions and suppliers with more precise

and detailed instructions on the appearance.

May result in a subjective evaluation due to

varying quality of boundary samples prepared by

designer. Require preparations of samples for

each surface, tailoring to specific purposes.

Annotations Require no task such as preparations of

boundary samples or instructions in line with

Appearance Grades.

May cause evaluation errors because annotations

should be made to drawings based on verbal

discussion or arrangement between parties concerned.

4. INSPECTION AND EVALUATION IN LINE WITH APPEARANCE GRADES

The designer should decide Appearance Grades in line with the grade specifications in Table 4.1, and specify them on the drawing in accordance with Subclause 4.2. Visual inspection should be performed based on the grade specifications.

In the case where the designer requires appearance specifications that are out of the grade specifications, he/she can define particular requirements on the drawing, or provide instructions using boundary samples in accordance with Clause 5. The decision of the Appearance Grades shall be made, taking into account the specific needs of product categories.

8. “Sony badges” and “key tops” were bundled together in a group for the grade specifications, but “badges” of general use are grouped with key tops so that a wide array of badges can be evaluated. The Sony badges shall meet no other requirements but Appearance Grade 0.

SS-00274-2005

4.1 Inspection Using Dot Gauge

4.1.1 Inspection for defects

Generally, the defects (bumps, dust, scratches, dents, and the like) on the cosmetic surface should be visually inspected and evaluated according to the criteria in Table 4.2. In case any disputes arise on evaluation results, purchase the Dot Gauge?2 shown in Figure 4.1 to measure the size of the defects.

Since the depths of the defects cannot be measured by the Dot Gauge, those of scratches and dents should be measured by the human eye. Consequently, evaluation of the defects shall be performed comprehensively, both on the depth by visual measurement, and on the size by visual inspection or Dot Gauge measurement.

When the criteria in Table 4.2 are not applicable to certain defects as described below, prepare boundary samples and use them in visual inspection with mutual agreement reached between the receiving divisions and the suppliers.

Example 1: Defects alike in size that look different to the human eye when they are in different hues.

Example 2: Defects on the surface that need appropriate inspection criteria depending on where they are found.

For purchase information about the Dot Gauge, access the following:

- Sony Group members: Test Tools List on the Mechanical Parts Standardization Committee website

- Sony’s business partners: TEST-TOOLS-LIST on the SPIRITS, a web-based system of Sony Corporation ?2 The Dot Gauge is prepared by Sony with reference to JIS P 8208 “Pulps - Estimation of contraries.”

4.1.3 Inspection of hues (color tones, tints, color heterogeneity, and glossiness)

View the surface of the test specimen for 10 seconds to evaluate colors with reference to a color reference sample and color boundary samples to verify that hues of the specimen meet those shown on the color boundary samples.

When measuring hues with a colorimeter, see the following acceptance criteria as a reference.

Table 4.4 Acceptance criteria for hues

Appearance Grade 0 Appearance Grade 1 Appearance Grade 2 Appearance Grade 3 ?E = 1.2 or less L? = ±1.0

a?/b? = ±0.3

Remark: Referential values for evaluating hues are provided in the “Painting/Printing on Plastic/Metal: Quality Test Report,” contained in Sony Technical Standards SS-00208 “Paint and Painted Parts - Quality Standard” and SS-00131 “Ink and Printed Parts - Quality Standard.”

Reference

L is the unit for lightness. (Lightness is synonym with brightness.)

a?/b? is the unit for hue and saturation (chromaticity), a? is for the red-green aspect and b? is for the yellow-blue aspect.

E is the difference between two colors, given by the following equation.

E = E?ab = [(L?)2 +(a?)2 + (b?)2)]1/2

Definitions of color terminology:

- Color: A sensation created in the visual system of human beings (and certain higher animals) by varying wavelengths of light falling on the retinal rods. Three main components of color are

hue, saturation, and brightness.

- Hue: Attribute of visual sensation which has given rise to color names such as: blue, green, yellow, red, purple, etc. (CIE 45-25-215.)?3 Hue differences depend primarily on

variations in the wavelength of light reaching the eye. (Color tone and tint)

- Saturation: Attribute of a visual sensation which permits a judgment to be made of the proportion of pure chromatic color in the total sensation. (CIE 45-25-225.) ?3The smaller the content of

white, gray, or black, the more intense the color is. ( Purity)

- Brightness: Attribute of a visual sensation according to which an area appears to emit more or less light. (CIE 45-25-210.) ?3The perceived amount of light coming from an area.

?3 Normative references: CIE (Commission Internationale de l’Eclairage) is an international body that

recommends standards and procedures for quantifying lighting and colorimetry.

DESIGNATION METHODS AND CRITERIA

FOR APPEARANCE PARTS SURFACE

1. BACKGROUND AND HISTORY

It was hard to give a written provision for design standards (required appearance) and evaluation criteria for appearance surfaces of parts, and the evaluation was entrusted to the parts quality assurance division.

The appearance inspection was, however, a sensory inspection and it had been impossible for us to establish a company-wide uniform standard for the following reasons: (1) different persons make different evaluations; (2) faults of the same sort look more conspicuous in one part than in others; (3) different evaluation criteria apply to different products for faults of the same degree. This resulted in variations in evaluation among different suppliers and overseas plants, not to mention different in-company divisions.

The “Surface Treatment Quality Standard Arrangement Working Group” was established in 1992 to review the quality standards for different kinds of surface treatment. Since June 1996, the working group has also been making effort to clarify the standards for evaluating appearance.

A survey made into the currently used evaluation methods found the followings. Sony P arts Center

(Quality Assurance Div. of the Procurement Center, in charge of consumer products), prepared a “master boundary sample” according to the “Appearance Evaluation Certification System” and used it as the appearance evaluation criterion for consumer products. Atsugi Technology Center (Quality Assurance Div.

in the Procurement Center, in charge of non-consumer products), on the other hand, made a dot gauge to take a quantitative approach. The working group then evaluated differences in evaluations using the “master boundary sample method” adopted by SPC and the “dot gauge” adopted by Atsugi to find that the two evaluation results corresponded to each other with a probability of 80 to 85%. It therefore concluded that a company-wide unification of standard was possible and hence this Sony Technical Manual (STM) was established.

The main approach taken was the quantitative method with dot gauge, which did not require preparation of boundary samples. It was not, however, all-purpose and, depending on the type of part, there might be cases where it was more efficient to make boundary samples than to use a dot gauge. The best possible way was to use either one, or both, of the two methods appropriately on a case-by-case basis in an effort to minimize variations in appearance evaluation.

2. ESTABLISHMENT OF APPEARANCE EVALUATION CRITERIA

1) Consideration was originally given to make a Sony Technical Standard (SS) under the title of “Surface

Treatment Appearance Evaluation Criteria.” Since, however, the SS was a mandatory application and that might cause some problems in its operation (description of requirements in drawings by designers, for example). Accordingly, the criteria have been established as an STM, and each division should be responsible for how to operate the criteria. Some members of the working group insisted on making an SS to implement compulsory application both in Japan and foreign countries. For the time being, however, the criteria would be operated as an STM to be later switched to an SS as situations necessitated.

2) Woodworked parts were beyond the scope of this Manual, though they required appearance evaluation,

as application of this Manual on them was technically hard.

3) Popularly used terms such as nibs, dust, scratches, and dents were collectively categorized into “faults.”

4) Though it had been first considered to use symbols on drawings, the wording “Appearance grade X” was

employed as penetration of many different types of symbols would be hard.

5) The test environment specified in Clause 7 was established in consideration of the test environment

standards (stipulated in JIS Z 8723 “Methods of Visual Comparison for Surface Colours”) and actual operations at different divisions and suppliers. Some members of the working group pointed out that unique standards should be provided for the evaluation of faults and printings evaluation, and the evaluation of color tone, which were to be made under different test environments. The criteria were, however, unified with certain allowances in details.

SS-00274-2005 Appendix

3. SECOND EDITION (REVISED IN 2000)

3.1 Revised Points

The first edition established evaluation criteria for appearance parts surface, using the dot gauge. After the establishment, some complaints have been heard that not all evaluations could be done in accordance with the stipulated criteria, and that descriptions of remarks in drawings were hard to be uniformed. As countermeasures, each division concerned requested designation by appearance grade, boundary sample, or notes in drawings. Designation by appearance grade only was found to be insufficient for the current situation, and the second edition established these three designation methods. Accordingly, the title was changed to “Designation Methods and Criteria for Appearance Parts Surface.”

However, it should be noted that about 60 to 70% of existing parts can be designated by appearance grade.

Therefore, each division had better promote the designation by appearance grade, which enables quantity evaluation of appearance surfaces.

3.2 Addition of Appearance Grade 0

Appearance grade 0 was added as the severest specification, which was established based on a request from the Personal Video division that the appearance grade 1 was not strict enough.

The addition of grade 0 only was a result of an anxiety of further needs for severer specifications, which might lead to too many appearance grades and complex designations.

Grade 0 was originally named “special grade” which was finally rejected taking into consideration future needs for severer grades. They would be named “grade 00”, “grade 000”, etc.

3.3 Abolition of Appearance Grade Selection Standard

Application examples (equipment, parts, positions) were abolished, as they could cover not all kinds of applications and there might be confusions on the contrary. As a substitute, specifications of each appearance grade were included. Application examples were hard to be defined by each product category, and should be determined by each division.

3.4 Addition of Another Designation by Appearance Grade

Another designation by appearance grade, when requirements exceed the specifications of grades, was added. It should be done by describing required specifications in drawings. The described specifications would be further determined to be added as one of the appearance grades, if it is necessary.

3.5 Revision of Describing Methods in Drawings

1) The second edition specified to describe requirements as remarks in drawings. The former edition

specified to describe them in “FINISH” columns in drawings, which did not match other related Quality

Standards that adopted the remarks description. Moreover, the number of this Manual (STM-0054)

should be described in drawings.

2) The second edition specified to indicate “Appearance surface” in drawings, to tell the target area of the

surface finish. It was not specified in the former edition, though it had been actually described.

3.6 Figure of Dot Gauge

Reference to JIS P 8208 “Pulps - Estimation of Contraries” was added, to clarify that the dot gauge was prepared by Sony based on the JIS standard.

Dot gauge drawing was prepared as follows.

Name: Dot gauge J-6470-570-A

Material of dot gauge: UP, t 0.1, transparent

Quality of dot gauge: Printing grade “PO-2” (SS-00131 “Ink and Printed Parts - Quality Standard”)

Appearance grade 1 (STM-0054 “Designation Methods and Criteria for

Appearance Parts Surface”)

3.7 Addition of Meaning of “Uniformity Ratio” of Illuminance

In Sub-clause 7.1.2, the meaning of “uniformity ratio” of illuminance was added.

3.8 Deliberation on “Appearance Grade Symbols”

A request to symbolize appearance grades as “CS-x” (Cosmetic Surface) was not adopted as too many

symbols would incur confusions, and “Appearance grade X” has already prevailed.

APPEARANCE SPECIFICATIONS AND

INSPECTION CRITERIA FOR COSMETIC PARTS

1. BACKGROUND AND HISTORY

This Sony Technical Standard is published as an upgrade version of STM-0054, which was first issued on April 20, 1998. The reasons for releasing this Standard are as follows:

1) When drafting the text of STM-0054, there were some requests to publish it as a Sony Technical

Standard, which shall be abided by all those involved in manufacturing Sony commercial products, rather than in a Sony Technical Manual that should be used as a reference. However, there was another argument that, before forcing every individual to comply with it, we should widely disseminate relevant information on the cosmetic surface quality to all parties concerned. As more than 7 years have passed since the release of STM-0054, its recognition and use are growing company-wide.

2) In the “Sensory Inspection Training (SIT),” which was promoted under the initiative of Quality Assurance

Department of P rocurement Center at Sony Headquarters (QA Dept. at HQ), instructors focused on trainings using master boundary samples. Recent structural changes in organizations, however, made it difficult for the department to solely hold SIT courses, and necessitated us to carry out trainings for visual inspection in a self-learning way.

3) According to the increase of smaller size commercial products on the market, the importance of

appearance quality of cosmetic parts is increasingly being recognized. DI Company offers SIT courses using its own standard of “Appearance criteria for PV and PI products,” inviting instructors from Quality Assurance Department of Kohda TEC. The QA Dept. at HQ also holds SIT courses in association with the Kohda TEC. In response to these moves, methodology of the SIT is shifting from that with master boundary samples tailored to specific uses in each division, to that with the Dot Gauge, which allows us to conduct an objective and quantitative evaluation.

4) In view of the actual situation, described 1) to 3) above, Engineering Standardization Office of Advanced

Design Technology Center and the QA Dept. at HQ discussed and reached an agreement that the Dot Gauge shall be used as a company standard in SIT courses as well as in visual inspection on the ground.

Following the agreement, this Sony Technical Standard, SS-00274, is published based on approval from the Mechanical Parts Standardization Committee.

2. MAJOR CHANGES IN UPGRADING FROM MANUAL TO STANDARD

Changes to the content in upgrading from the obsolete STM-0054 (Sony Technical Manual) to this new SS-00274 (Sony Technical Standard) are summarized as follows:

1) The English version of SS-00274 is retitled “Appearance Specifications and Inspection Criteria for

Cosmetic P arts,” which is different from “Designation Methods and Criteria for Appearance P arts Surface,” the title of STM-0054.

2) The word “STM-0054” is replaced with “SS-00274” throughout the whole text. It is noted that the

“STM-0054” specified in existing drawings should be read as “SS-00274.”

3) Since the Dot Gauge itself was largely modified, the image of Figure 4.1 in this Standard is updated

based on a new Dot Gauge. Although an Adobe Illustrator was used in the past, original data of the new Dot Gauge was designed on a CAD system in the hope of improving the accuracy of dot dimensions.

Even though dot dimensions were measured in laborious detail, those with tolerances of ± 20% to ± 30% remain for minute dots with dimensions of 0.01 mm2 to 0.03 mm2 and the dots in seventeenth and eighteenth columns, which are substantially in the form of extra-fine lines in parallel to a laser scanning direction, because of differences in the printing quality and limitations of the resolution of laser printers

(i.e., approx. 10 μm). A final prototype of a new Dot Gauge was carefully reviewed by those concerned,

including trainers of the SIT, and was approved for use in visual inspection of cosmetic parts. The following modifications, other than those related to the dot dimensions, were made to the new Dot Gauge: 1) J-6470-570-A, a part number of jig tool, is added, 2) vertical and horizontal coordinates are described to provide the user with means for locating dot positions, and 3) the side lengths of the 100-mm squares in Table 4.2 are changed from those between the axes of bold lines to those of inner dimensions.

4) As an appropriate light source, “three-band neutral white fluorescent lamp,” which has a high lamp

efficiency and color rendering properties, is added to 7.1.1 Light sources. This lamp is easily available in comparison to the pure natural daylight fluorescent lamp or the genuine color fluorescent lamp.
