Sum

16、mary of Practice4.1 A number of tests for materials and products used incleanrooms or to fabricate cleanrooms have been issued byvarious organizations such as ASTM and IEST. The purpose ofthis practice is to identify test methods used to determine theproperties of various materials and products used

17、 in clean-rooms. A brief description and some of the features of thevarious tests are also given to aid interested users in selectingthe test or groups of tests that have the ability to meet theirneeds for evaluating existing and candidate cleanroom prod-ucts.4.2 Table 1 lists the tests suggested to

18、 measure specificproperties of various cleanroom materials and products. Whereno test is presently listed it is probable that a test will berequired and must be identified or developed if none exist atpresent.5. Significance and Use5.1 This practice is not intended to advocate or discourageuse of an

19、y particular test method. It is intended for informationonly, and to provide a useful guide for further detailed study,test, and evaluation of cleanroom materials and products.6. Hazards6.1 Hazards can be present when using many of the refer-enced tests. Each of the referenced test methods warn ofpo

20、ssible hazards and suggest means to minimize them. If toxicor other hazardous materials are identified, they must behandled properly per the reference documents.7. Procedure7.1 Table 1 lists the types of materials and cleanroomproducts of present interest and recommends the test methodsto be used to

21、 evaluate these materials. Where several tests arelisted, it is suggested that all of them be considered at leastinitially to evaluate the product and allow properties to beevaluated. Test results will provide relative values for theproperties tested such as particle count per unit area, NVR perunit

22、 area or mass, or outgassing at a given temperature,typically at 125C. No pass/fail values or minimum require-ments are specified because there are no established values forcleanliness for any of the products that are listed. Users shouldrank materials for contamination generation potential andsuita

23、bility for cleanroom use based upon test results and addedfactors such as conditions of use, consistency of test results,testing bias, and cost and availability of the products as-used incleanrooms. It is normal for properties to vary somewhat fromlot to lot, so it is important to test several lots

24、to evaluatereproducibility of results and product consistency.NOTE 1If there is a specific interest in identifying or developing testmethods for areas shown as having no tests at present, or that the test isNot Applicable, Committee E21 will consider any such suggestions.7.2 Test methods as noted in

Report8.1 The report should identify the material or product tested,the

30、 vendor, supplier or source, any part number or otheridentifying specification, the test or tests performed, and theactual test results.8.2 The report also may compare test results for differentlots from the same manufacturer or supplier, or for differenttypes of products, and rank performance and t

31、est results. It alsois useful to identify specific products or materials as beingacceptable for use in particular types of facility or for specificuses or applications.9. Precision and Bias9.1 There is no precision or bias value possible for thispractice. Many of the referenced documents do include

32、preci-sion and bias statements. They should be considered on anindividual basis for each test method.10.
