Theproperties enumerated in this table and the tests defined areexpected to provide identification of the compounds selected.They are not necessarily suitable for direct application indesign because of differences in shape of pa
22、rt, size, loading,environmental conditions, etc.4.2 Classes are designated by the cell number for eachproperty in the order in which they are listed in Table 1.NOTE 3Because of the large number of property requirements, theproperties of classes are divided into groups for easy identification of thes
23、elected materials. The groups are the following: kind of resin incompound, strength properties, and dimensional stability. The classnumbers are grouped as shown by the following example:TABLE 1 Class Requirements for Rigid Poly(Vinyl Chloride) and Related PVC and CPVC Compounds for Building Products

36、same thickness supplied inadvance by the seller of the material.7. Sampling7.1 A batch or lot shall be considered as a unit of manufac-ture and may consist of a blend of two or more production runsof material.7.2 The material shall be sampled in accordance with theprocedure described in the General
37、and Specific SamplingProcedures, as applicable, of Practice D 1898. Adequate statis-tical sampling prior to packaging shall be considered anacceptable alternative.8. Physical Requirements8.1 Test values for specimens of the material prepared asspecified in Section 10 and tested in accordance with Se
38、ction11 shall conform to the requirements given in Table 1 for theclass selected.8.2 The compound, when tested in accordance with TestMethod D 635, shall not exceed an average extent of burn of100 mm 4 in. with an average time of burn not to exceed 10s.

Specimens cut from laminates of compression-molded sections shall not be used unless it is shown by te
46、st thatcomplete fusion is obtained. Specimens cut from flat extrudedprofile samples shall be used for dropped dart impact andweatherability tests. It is understood that a material shall not betested without also specifying the method of specimen prepa-ration. When comparative tests of materials are
47、desired, thegreatest care shall be taken to ensure that all specimens areprepared in exactly the same way used to certify the cell classof the compound. Procedures used in preparing the testspecimens shall be as recommended by the supplier for eachspecific compound.NOTE 7It is possible that a specim
48、en taken from a finished productwill not produce the same results as a specimen prepared by the methodused for purposes of cell class testing and certification.11.
