Method for Verification of an Inclined Oil Manometer5.Significance and Use5.1The test procedures provide a standard method of obtaining data for research and development,quality control, acceptance and rejection under specifications,and special purposes.5.2The data obtained by these test methods are applicable to the material under conditions of the particular test and are not necessarily the same as obtained in other environments in use.6.General Test Conditions6.1Tests shall be conducted under known conditions of temperature and humidity or as specified in the individual test procedure.The product shall be conditioned undeflected,and undistorted at the temperature and humidity of test for at least 12h before being tested.In cases of dispute,the tests shall be made at a temperature of2362°C and in an atmosphere of50 65%relative humidity.6.2It is recommended for referee purposes that all tests shall be performed7days or more after the foam has been manufactured.7.Sampling7.1When possible,the completed manufactured product shall be used for the test specified.Representative samples of the lot being examined shall be selected at random as required.7.2When it is necessary or advisable to obtain specimens from the articles,as in those cases where the entire sample is not required or adaptable for testing,the method of cutting and the exact position from which specimens are to be taken shall be specified.The density and the state of cure may vary in different parts of thefinished product,especially if the article is of complicated shape or of varying thickness,and these factors affect the physical properties of the specimens.Also,the density is affected by the number of cut surfaces on the specimen.If a test specimen is die cut,sufficient time should be allowed for complete recovery of the thickness across the full width of the specimen.7.3When thefinished molded product does not lend itself to testing or to the taking of specimens because of complicated shape,small size,metal or fabric inserts,adhesion to metal,or other reasons,molded test slabs as agreed upon between the supplier and the purchaser shall be prepared.7.4When differences in test results arise due to the difficulty in obtaining suitable specimens from thefinished parts,the supplier and the purchaser may agree upon an acceptable location to take the specimen.8.Measurement of Test Specimens8.1Measure the length and width with a scale or tape.Take care not to distort the foam.8.2Measure thickness up to and including25mm using a dial-type gage with a minimum foot area of650mm2.Hold the pressure of the dial foot to170635Pa(Note3).Thicknesses over25mm may be measured with a dial gage,a sliding caliper gage,or as specified in8.1.When a sliding caliper gage is employed,make the gage setting with the gage out of contact with the foam.Pass the specimen through the previously set gage:the proper setting shall be the one when the measuring faces of the gage contact the surfaces of the specimen without compressing it.N OTE3—For soft foams having compression force deflection values less than1.65kPa,the pressure on the dial foot shall not exceed100Pa.8.3The scale,tape,or gage shall be graduated so as to permit measurements within61%of the dimensions to be measured.8.4Unless otherwise specified,results shall be the mean of the measurements.TEST A—DENSITY TEST9.Scope9.1This test method covers determination of the density of uncored foam by calculation from the mass and volume of the specimen.The density value thus obtained applies only to the immediate area from which the specimen has been taken.It does not necessarily relate to the bulk density of the entire molded pad.N OTE4—ISO845is a similar test,but there are technical differences.10.Test Specimen10.1Core Density—A representative specimen of regular shape,circular or square without skins or densification lines, not less than1000mm3in volume,shall be cut from a portion free of voids and defects and as near as possible to the section from which the tension and tear specimens were taken.10.2Section Density—A representative specimen with skins on the top and bottom surface measuring at least0.1m2in area by full-part thickness shall be cut from an area free of voids and defects and as near as possible to the location from which the tension and tear specimens were taken.When these dimensions are not possible,the largest representative portion as agreed upon between the supplier and the purchaser shall be used.11.Number of Specimens11.1One specimen shall be tested,unless otherwise agreed upon by the supplier and thepurchaser.12.Procedure12.1Determine the mass of the specimen within1%. 12.2Determine the dimensions of the specimen in accor-dance with Section8,and calculate the volume.13.Calculation13.1Calculate the density in kilograms per cubic metre as follows:Density5M/V3106(1) where:M=mass of specimen,g,andV=volume of specimen,mm3.14.Report14.1Report the following information:14.1.1Density to the nearest0.1kg/m3,and14.1.2Type of specimen,core or section.15.Precision and Bias15.1See Section131for Precision and Bias statements.TEST B1—INDENTATION FORCE DEFLECTION TEST—SPECIFIED DEFLECTION16.Scope16.1This will be known as the indentation force deflection test and the results as the IFD values.This test consists of measuring the force necessary to produce designated indenta-tions in the foam product,for example,25and65%deflec-tions.(Appendix X3).N OTE5—ISO2439is a similar test,but there are technical differences.17.Apparatus17.1An apparatus having aflat circular indentor foot203 mm in diameter connected by means of a swivel joint capable of accommodating the angle of the sample to a force-measuring device and mounted in such a manner that the product or specimen can be deflected at a speed of50to500 mm/min.The apparatus shall be arranged to support the specimen on a level horizontal plate which is perforated with approximately6.5-mm holes on approximately20-mm centers to allow for rapid escape of air during the test.Special support for contoured molded pads shall be perforated in the same manner as theflat plate unless agreed upon between the supplier and the purchaser.Pads longer than the base plate shall be supported from distortion at the4.5-N contact force. 18.Test Specimen18.1The test specimen shall consist of the entire product sample or a suitable portion of it,except that in no case shall the specimen have dimensions less than380by380by100 mm.Specimens less or different than100mm in thickness shall have the thickness noted on the test report.18.2The IFD values for molded products are dependent on the specimen dimensions.Higher values are generally obtained for specimens that retain all molded surfaces.19.Number of Specimens19.1One specimen shall be tested,unless otherwise agreed upon by the supplier and the purchaser.20.Procedure20.1Place the test specimen in position on the supporting plate of the apparatus.If the product has one side cored or honey-combed,this face shall rest on the perforated plate.The specimen position shall be such that whenever practicable the indentation will be made at the center of all articles,except where another location is agreed upon by the supplier and the purchaser.20.2Preflex the area to be tested by twice lowering the indentor foot to a total deflection of75to80%of the full-part thickness at a rate of250625mm/min.Mark the location of the test area with a pen by circumscribing the indentor foot while under a4.5-N force.Allow the specimen to rest661 min after the preflex.20.3Bring the indentor foot into contact with the specimen and determine the thickness after applying a contact force of 4.5N(Note6)to the indentor foot.Indent the specimen at50 65mm/min25%of this thickness and observe the force in newtons after6063s.Without removing the specimen increase the deflection to65%deflection,allowing the force to drift while maintaining the65%deflection,and again observe the force in newtons after6063s.N OTE6—For super-soft foam,foam with a25%IFD less than40N,a reduction of pressure on the indentor foot shall be allowed.Sufficient contact force to make an accurate initial thickness measurement is required.21.Report21.1Report the force in newtons required for25and65% indentation or other indentations(Note7).Thesefigures are known as the25%and65%IFD values,respectively.Report also length,width,and thickness of the specimen,if non-standard and the ratio(comfort factor Appendix X3)of65%to 25%IFD values.N OTE7—Indentation deflection tests,other than25and65%,as well as a25%return value(25%RT),may be specified as agreed upon between the supplier and the purchaser.22.Precision and Bias22.1See Section131for Precision and Bias statements. TEST B2—INDENTATION RESIDUAL GAGE LOADTEST—SPECIFIED FORCE23.Scope23.1Cellular foam products have been traditionally checked for indentation force deflection by determining the force required to effect a25%deflection.In seating,on the other hand,the interest is in determining how thick the padding is under the average person.Two measurements are called for to meet the requirements of this test method.The force deflection is determined by measuring the thickness of the pad under a fixed force of4.5N,110N,and220N,on a323-cm2circular indentor foot.23.2This determination shall be known as the Indentation Residual Gage Load and the measurements as the IRGL values. N OTE8—ISO2439is a similar test,but there are technicaldifferences.24.Apparatus24.1An apparatus having aflat circular indentor foot203 mm in diameter connected with a swivel joint for applying forces of4.5N,110N,220N and330N shall be mounted over a level horizontal platform that is perforated with approxi-mately 6.5-mm holes on approximately20-mm centers to allow for rapid escape of air during the test.The distance between the indentor foot and the platform shall be variable to indent the specimen at a speed of50to200mm/min for thickness measurements.The apparatus shall be equipped witha device for measuring the distance between plates.24.2Special support for contoured molded pads shall be perforated and agreed upon between the supplier and the purchaser.Pads longer than the base plate shall be supported from distortion at the4.5-N contact force.25.Test Conditions25.1When possible the completed manufactured product shall be used.In the case of tapered cushions,the location of the area for measurement is to be agreed upon between the supplier and the purchaser.In the case afinished part is not feasible for test,380by380-mm specimens of an average thickness are to be cut from the cushion.25.2The IRGL values for molded products are dependent on the specimen dimensions.Difference values are generally obtained for specimens that retain all molded surfaces.26.Number of Specimens26.1One specimen shall be tested,unless otherwise agreed upon by the supplier and the purchaser.27.Procedure27.1Test the whole test specimen or a minimum area of380 by380mm.Preflex the specimen twice with a330N force at 200620mm/min.Allow to rest661min.Position the specimen in the test apparatus with any cored or convoluted surfaces resting against the perforated bottom plate.27.2Bring the indentor foot into contact and determine the thickness of the specimen with the4.5-N load on the indentor foot.27.3Apply the110-N force at5065mm/min with the indentor foot and indent the specimen until the force is carried by the specimen.Determine the thickness at110N after maintaining the force for6063s.27.4Without removing the specimen apply the220-N force at5065mm/min with the indentor foot and further indent the pad until this load is carried.After6063s under load, determine the thickness of the pad.28.Report28.1Report the specimen thickness after6063s at4.5N, 110N,and220N.Thesefigures are known as the IRGL values, respectively.Report also the length,width,and thickness of the specimen.29.Precision and Bias29.1Round robin testing to determine the precision of this method is being planned and the data will be available by2002.TEST C—COMPRESSION FORCE DEFLECTIONTEST30.Scope30.1This test consists of measuring the force necessary to produce a50%compression over the entire top area of the foam specimen.N OTE9—ISO3386is a similar test,but there are technical differences.

foam.Measurements are madefortensile stress,tensile strength,and ultimate elongation.N OTE 17—ISO 1798is a similar test,but there are technical differences.46.Apparatus46.1Specimens —The specimen for tensile tests shall be stamped out with a die of the shape and dimensions shown in Fig.1,or Die A of Test Methods D 412.The die shall be sharp and free of nicks in order to prevent leaving ragged edges on the specimen.The D 412Die is the preferred die and is identical in dimensions to the ISO 1798Die.46.2Bench Marker —The marker shall have two parallel marking edges 1to 3mm in thickness and spaced 20or 25mm apart on centers.46.3Measurements —The dimensions of the test specimen shall be determined with a suitable gage in accordance with Section 8.46.4Machine—Tensile tests shall be made on a power-driven machine complying with the following requirements:46.4.1The machine shall be equipped with a load cell or force measuring device that can measure the maximum applied force.The test speed shall be 500650mm/min,and shall be uniform at all times.46.4.2The machine may be equipped with a device gradu-ated to 2.5mm for measuring the elongation.The use of non-contact extensometers may similarly be used for determin-ing elongation.Extensometers that clip on to the specimen generally are unsuitable for flexible foam.For testing dumbbell specimens,the machine shall have either screw-type flat plate grips or a type of grip that tightens automatically and exerts a uniform pressure across the gripping surfaces,increasing as the tension increases to prevent slipping.47.Test Specimens47.1The test specimens shall be cut from flat sheet material 12.561.5mm thick.The foam rise shall be in the thickness direction,unless otherwise agreed upon by customer and supplier.The top and bottom surfaces shall be parallel and free of skin.The cut edges shall be perpendicular to the top surface and be free of ragged edges.The length of the tabs may be adjusted to fit machine conditions provided that all other requirements remain constant.48.Number of Specimens48.1Three specimens per sample shall be tested.The value reported shall be the mean value of those observed.49.Procedure49.1Set the grip separation at a minimum of 62.5mm forthe D 3574Die and at a minimum of 75mm for the D 412Die A.Place the dumbbell tabs in the grips of the testing machine,using care to adjust them symmetrically,in order that the tension will be distributed uniformly over the cross section.The test shall be run at a speed of 500650mm/min,unless otherwise specified by agreement between customer and sup-plier.Start the machine and note continuously the distance between the two bench marks.Record the stress at the corresponding elongation or if an automatic recording device is used,it will record the data continuously.At rupture,measure or record elongation to the nearest 10%.50.Calculation50.1Calculate the tensile strength by dividing the maximum breaking force by the original cross-sectional area of the specimen.50.2Calculate the stress by dividing the force at a prede-termined elongation by the original cross-sectional area of the specimen.50.3Calculate the ultimate elongation,A ,by subtracting the original distance between the bench marks from the total distance between the bench marks at the time of rupture and expressing the difference as a percentage of the original distance,as follows,or use the grip separations in a similar calculation.A ,%5@~d f 2d o !/d o #3100(4)where:d o =original distance between bench marks,andd f =distance between bench marks at the break point.50.4The value reported shall be the mean value of all specimens tested.51.Report51.1Report the following information:51.1.1Tensile strength in kilopascals,51.1.2Stress in kilopascals at a predetermined elongation,and51.1.3Ultimate elongation,in percent,and whether bench marks,grip separation or extensometers were used to measure elongation.51.1.4Crosshead speed,if other than 500mm/min.52.Precision and Bias52.1See Section 131for Precision and Bias statements.TEST F—TEAR RESISTANCE TEST53.Scope53.1This test method covers determination of the tear propagation resistance of foam.The block method,as de-scribed,measures the tear resistance under the conditions of this particular test.N OTE 18—ISO 8067is a similar test,but there are technical differences.54.Apparatus54.1Tear resistance shall be measured on a power-driven apparatus which will indicate the force at which rupture of the specimen takes place.An automatic machine may beusedFIG.1Die for Stamping TensionSpecimens。
TEST C—COMPRESSION FORCE DEFLECTION TEST30. Scope30.1 This test consists of measuring the force necessary to produce a 50 % compression over the entire top area of the foam specimen.NOTE 8 — This standard and ISO 3386 address the same subject matter, but differ in technical content; and results cannot be directly compared between the two methods. NOTE 9 — Compression force deflection tests other than at 50 % may be specified, as agreed upon between the purchaser and the supplier, following the procedure in Section 34.31. Apparatus31.1 An apparatus having a flat, fixed compression foot, larger than the specimen to be tested, connected to a force-measuring device and mounted in a manner such that the product or specimen can be deflected at a speed of 50 to 500 mm/min. The apparatus shall be arranged to support the specimen on a level horizontal plate that is perforated with approximately 6.5-mm holes on approximately 20-mm centers to allow for rapid escape of air during the test.32. Test Specimens32.1 The test specimens shall have parallel top and bottom surfaces and vertical sides. The thickness shall be no greater than 75 % of the minimum top dimension. The standard specimen shall be 50 mm by 50 mm by 25 mm in thickness. Larger specimens are preferable, where possible.32.2 Specimens shall be a minimum of 2500 mm 2 in surface area and have a minimum thickness of 20 mm.32.3 Unless otherwise agreed upon by purchaser and supplier, specimens from molded parts shall be cut from the core material at least 10 mm below the molded surface. Note in the report if the specimens contain one or more molded surfaces resulting from insufficient core material or contractual agreement.33. Number of Specimens33.1 Three specimens per sample shall be tested. The value reported shall be the mean value of those observed.34. Procedure34.1 Place the specimen, centered in the line of the axial load, on the supporting plate of the apparatus. If the product has one side cored or convoluted, rest this face on the perforated plates.34.2 Preflex the specimen twice, to a deflection of 75 to 80 % of its original thickness, lowering and raising the compression foot at a rate of 250±25 mm/min, allowing the compression foot to fully clear the specimen after each preflex. Allow the specimen to rest for a period of 6±1 min after the final preflex.34.3 Bring the compression foot into contact with the specimen at a rate of 50±5mm/min and determine the thickness after applying a contact load of 140±14 Pa to the specimen area (see Note 2). Compress the specimen 50 % of this thickness at a rate of 50±5 mm/min and determine the final force, in N, after 60±3 s (see Note 8).35. Report35.1 Report the thickness after contact force, the 50 % compression deflection value in kilo Pascal, and the dimensions of non-standard specimens. Indicate if the sample was cored or convoluted. Report if the specimens contained one or more molded surfaces.36.
