Summary 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 te

18、st methods used to determine theproperties of various materials and products used 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 ex

19、isting and candidate cleanroom prod-ucts.4.2 Table 1 lists the tests suggested to 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. Signifi

20、cance and Use5.1 This practice is not intended to advocate or discourageuse of any 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 u

21、sing many of the refer-enced tests. Each of the referenced test methods warn ofpossible 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 c

22、leanroomproducts of present interest and recommends the test methodsto be used to 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
