Create Tips - MaterialsIncorporating the latest of system release 5.0IntroductionThis series of presentations gives a recommended step-by-step procedure for creating MDSs in the IMDS system. While this presentation gives recommendations on how to input data, it does not replace the individual OEM requirements that can be found on: Public pages> FAQ > OEM Specific Info Or specific product recommendations found after login on: RecommendationCopyright © 2007 Electronic Data Systems Corporation2About the Create Tips Series• Originally, the create tips gave information on materials, components, and semi-components. However, by popular demand, the one large document has been divided into smaller documents for ease of use. This is the largest document because the rules and requirements are more complex for materials than for components and semi-components.Copyright © 2007 Electronic Data Systems Corporation3Basic MDS StructureNote - The requirement is to reduce all parts to Basic Substances. At the moment, the system allows mixing of types at the same level - there are some OEM’s and Tier One’s that require all siblings be of the same type - be sure to understand your customer’s requirements before expending a lot of effort – please review Recommendation 001 and other recommendations that pertain to your product.4Component (single part) Material A Basic Substance 1 Semi-component 1 Material B Basic Substance 2 Semi-component 2 Material C Basic Substance 3Mixing types will generate a WarningCopyright © 2007 Electronic Data Systems CorporationWhere To Find Recommendations• The Recommendation link will bring up a screen similar to the following • IMDS 001 is what is commonly referred to as Recommendation 001 • You should check this screen once a month for changesWhen there is an “a” and a “b” part to the Recommendation, there is a file link in “a” that does not work. What it is supposed to link to is in file “b”Copyright © 2007 Electronic Data Systems Corporation5MDS or Module?• DecideMDS or Module? Basic building Block used Several timesCreate a ModuleLimited reuse If you wish, can also create MDS for a basic building block • MDSs require all 3 chapters to be filled in Create an MDSModules only have Modules only have the Ingredients the Ingredients chapter so cannot chapter so cannot be assigned to an be assigned to an Organization Unit Organization Unit nor sent to a nor sent to a recipient recipient- Ingredients, Supplier Data, Recipient Data • Modules only require Ingredients to be defined as the rest gets set when used in an MDSCopyright © 2007 Electronic Data Systems Corporation6Creating Your MDSWhile you can create Components and SemiComponents (if used) within the ingredients tree, Materials must be created separately. It is strongly suggested that you get your materials into the system first. You have three choices for getting material information into IMDS:– Use published materials (use at own risk if not entered by manufacturer of materials or IMDS Committee - anyone can publish and there is no quality check) – Have your supplier input material MDS and send it to you (best if you have time and a cooperative supplier) – Build the material tree yourself and internally release (time consuming and you may not have information)Copyright © 2007 Electronic Data Systems Corporation7Create a MaterialDo You Have to Create a Material?• The first question to ask is “Do I have to create a Material?” – If your material is published to a public norm or standard then most OEMs would prefer that you use an IMDSCommittee Published Material • Do you manufacture the material? – If you do not manufacture the material then you should require your supplier to enter the data and either send or propose it to you. If you cannot get your supplier to enter the data – they must send you the breakdown of the product – ALL substances – a MSDS sheet is NOT sufficient to create a material. • Is the material already in IMDS – either created by my company, my supplier, or IMDS-Committee – The next section will give you some searching tipsCopyright © 2007 Electronic Data Systems Corporation9How to SearchFilters –Ingredients Page Filters•Article Name –the description given on the Ingredients page if your company created it or you are searching in Published data. The description from the Recipient Data page if it was sent/proposed to your company. Note: if you cannot find the MDS, you may want to do a wild card search as there must be an EXACT match to display and leading spaces may be an issue.•Part/Item No. –the Part/Item number from the Ingredients page if your company created it or you are searching in Published data. The information from the Recipient Data page if it was sent/proposed to your company. Note: if you cannot find the MDS, you may want to do a wild card search as there must be an EXACT match to display and leading spaces may be an issue.•ID-No. –the IMDS ID number•Language –only appropriate if searching for a material•Version ––Current –the highest version number or all the versions in edit mode if your company created it. The highest version number that you have visibility to if another company created it –warning –if your supplier uses the practice of creating a copy/new version every time they send to anothercompany, you may not have visibility to the latest version of the MDS and will need to use All Versions.–All Versions –All versions of the ID.•Development Sample Report –If checked, will only return MDSs where the Development Sample Report box has been checked on the Ingredients page •Note: The BEST way to find anything in IMDS is by IMDS ID.You must also be looking in the right place -–Was it created by your company or another–If you cannot find with current versions, try All versions–Use Wild card searches –e.g. if looking for published SAE 1010 steel, use *1010 in the Name fieldFilters –Creation Dates•Published / accepted / internally released –this option will return only RELEASED MDSs(whole number version) and whether they are created by your own company or a supplier or both will depend on how you set other flags.•Created (own MDS) –this option will return only MDSs and modules created by your company, regardless of whether they have been released or not.•Date -this option will limit your results to MDSs released during the time frame (if first box checked) or created during the time frame (if 2nd box check). Note: The dates must be given in the specified format. Only MDSs have the date tracked.Filters –Supplier Created•You can limit hour search to supplier data to data from a select list. By default, for materials, only IMDS-Committee materials will be returned.–Accepted MDSs –return only data that has been accepted by my company–Published MDSs –return only data that has been published–All –selecting this will search all suppliers –not just those on the list–Supplier List –restrict search returns to the suppliers listed. Material searches will automatically have the 3 IMDS-Committee companies listed (see next page for how to add/remove suppliers and a more complete discussion of how this works)–Save List –saves the supplier list for future sessions –this list is saved to the login ID•Note: when searching on Published materials , your supplier list will be supplemented by the IMDS-Committee materials. If you want these on the other tabs, you will have to customize your list.•Additional note –the “save list”from the search screen is also attached to the Receive screen allowing a company to have users focused on certain suppliers. There is a 2nd “save list”available on the Sent screen. •IF YOU DO NOT CHECK THE ALL BOX, ONLY THOSE DATASHEETS CREATED BY THE COMPANIES LISTED WILL BE RETURNED!!!!Materials TabComponents, Semi-Components, AllMDS/Modules TabFilters –Supplier List –Add•To add a supplier to the customized list, click on the• A search screen will appear where you can either search on a Company or an Org Unit•After a search, you select your supplier and hit apply –in this case, I have added KPTest to my list (note –the company numbers displayed are not from the production system.•Multiple suppliers may be selected to apply at one time if click individually on the desired companies or Org Units and then click on Apply.MaterialsTabFilters –Supplier List –Remove•To remove a supplier from the customized list, first highlight the supplier to remove (KPTest above) and then click on the •The results would be similar to below on the materials tabFilters –Organizational Info•Own MDSs–the search results will only return MDSs and not modules •Own Modules –the search results will only return modules and notMDSs•Assigned Org.-Unit –the search result will be limited to MDSs assigned to a particular Organizational Unit•Assigned Contact –the search result will be limited to MDSs with the contact person as selected•Last edited by me –the search result will be limited to those MDSs or Modules last edited by the user ID currently logged in•Note –The Contacts are from a pull-down list modified by the client manager under Administration > Contact PersonMaterial Search Tips•Best to use IMDS ID•Wild cards (*), partial names, etc. may also be useful (discussed later)•You only have access to materials your company has created, data that has been published, and data that was sent to your company and accepted.•The IMDS-Committee only publishes materials to a Public Norm and where that Norm has been defined by the basicsubstances that sum to 100%.

If you want a material standard published, send to the helpdesk and we will try to add. Not all standards contain a complete list of substances. We can only publish if the standard includes substances that sum to 100%. These have been added to your saved company list when searching for materials. A list of Public Norms can be found Public Pages > FAQ > General Info > What do the Norms/Standards acronyms mean? Guide to the IMDS Steering Committee Published Materials: – Stahl und Eisen Liste (313) - predominantly steels and steel alloys – no norm/standard on most of them but contain a material number of form 1.nnnn where nnnn is a 4 digit number. – IMDS-Committee (423) – coatings and alloys and also some semi-components – IMDS-Committee / ILI Metals (18986) – steels published to other standards not in the Stahl und Eisen Liste. If it is to a Public Norm/Standard, the Norm/Standard number is incorporated into the Material Name Since the same material may be known by one or more Public Norms, it is best to do a wildcard search on the number to find the material – e.g. to find SAE 1060, enter *1060 in the name field and then mouse over the ellipses (…) to get the entire name and the material you want.•• •Copyright © 2007 Electronic Data Systems Corporation24Create a MaterialBefore You Begin – Must Have Data• The following information will be required for you to complete data entry – – Know a minimum of 90% of the substances in the material – Material Classification – Applicable Public Norms/Standards – Applicable OEM In-House Norms – Applicable Material Symbols – Any special customer requirements – Recommendation 001 and any other Recommendation pertaining to the productCopyright © 2007 Electronic Data Systems Corporation26MDS or Module?• DecideMDS or Module?

The same philosophy guides the GADSL list ( Global Automotive Declarable Substance List – ) You will not find processing chemicals on the GADSL although some of them may be harmful. Neither IMDS nor the GADSL is an exhaustive list – with 100,000s of chemicals, it is impossible to list every CAS number. If a CAS number doesn’t appear on the GADSL does not mean it is not declarable/prohibited as the GADSL really is the category list and the reference list is just that – a reference. the GADSL is only updated once a year. IMDS can be updated based on a user request to the helpdesk. Before asking the helpdesk to add a CAS number, please run it through the CAS number check (at least 50% of the requests the helpdesks get have an incorrect CAS number) - /expertise/cascontent/registry/checkdig.html Not every substance with a CAS number is considered a basic substance in IMDS terms. There are alloys or “groups” that have been assigned a CAS number. Because the IMDS substance list is a validated list that has been developed over the years at a cost, it is NOT available for download and Use Conditions prohibit the use of the list in 3rd party software except where an agreement exists between the vendor and IMDS.••• •Copyright © 2007 Electronic Data Systems Corporation40Basic Substance Search Tips•Best to use CAS number -if it isn’t in the system, send an email to the helpdesk and ask that it be added–When the substance is added or the request is rejected, the helpdesk will notify the user•This is a European system and there are European spellings -aluminium vs aluminum, sulphur vs sulfur, etc.•Wild cards (*), partial names, etc. may also be useful–*resin will return all resins–Silicone will return all substances starting with silicone–*fibre will return Pseudo-substances that are usually used as fillers or natural occurring substances–Basic duromer, basic elastomer, basic oil, Thermoplastic elastomer and basic rubber will return pseudo-substances in those categories• A Pseudo-Substance gives an accurate description of the substance or the substance group but does not have a CAS-No. It is important to point out that these substances are accepted as real substances in IMDS and are not considered as wildcards. They are therefore allowed to be used within the 90% disclosure rule according to the IMDSRecommendation 001.

Pseudo substances can be used up to 100% of a material –however, it is doubtful that any material would be made of 100% of any substance or else you would be supplying a basic substance and if that is the case, you should not have to enter into IMDS.•Since search results are limited to 500 returns, it is not possible to look at a complete list of Pseudo Substances in the system. You will need to enter some information in the name field to find the type of Pseudo Substance you are looking for –for example:–Basic Duromer–many of these are resins–Basic Oil –limited list of oils –because many oils are PAHs, you will usually have to search by CAS number –Basic Polymer –many are ISO 1043 substances –you could also search on polymer name (e.g. *PA6, *EMAK, *FEP, etc.)–Basic Rubber –again you could either look through the entire list or enter the name in the field –a wildcard search works best (e.g. *ABR, *XCR, etc.)–Plasticizer –best to do a wildcard search –e.g. enter *plasticizer in the name field–Flame Retardant –several undeclarable/non-prohibited can be found by entering *1043-4 in the name field –Man-made fibers –can be found by entering Man-made in the name field–Natural fibers such as wool and hair –can be found by entering Natural in the name field–Thermoplastic Elastomers–can be found by entering Thermoplastic in the name field or by more specific searches on the name (e.g. *TPC, *TPV, etc.)–Soaps and other Thickeners –can be found by entering Thickener in the name field–Some other fillers can be found by entering the ISO 1043-2 description (e.g. MD for Mineral Powder). You might also try entering *1043-2 in the name field to find the fillers used in Thermoplastics.–Resins are frequently found by entering *resin in the name field•The above does not contain an exhaustive list, but guidelines on how to structure your search for pseudo substances.Jokers/Wildcards•You may use jokers/wildcards in your structure if BOTH of the following conditions are true:–The substance being replaced is not declarable or prohibited–The TOTAL of all undeclared substances (substances marked confidential or joker/wildcard) is a MAXIMUM of 10% -except whereexemption is given in a Recommendation•Jokers/Wildcards have the CAS number system and there are only 9 of them in IMDS:Find First Substance•Enter the entirecompound, or ashortened version ofit, or the CAS numberand click on SearchSearch hint:Sometimes less ismore -the more filtersyou fill in, the more ithas to match and thesearch may comeback unsuccessful.。
