Test Methods8.1 Determine the chemical resistance of a compound fol-lowing the procedure of Test Method D543 except the expo-sure
19、period shall be for 30 days. Note the chemical,concentration, test temperature, and resistance in accordancewith 8.1.1 8.1.4. This data is compiled in Table 1 andcomprises the six digits of the chemical resistance cell.8.1.1 The test chemical is designated from the alphanumeri-cal list of chemicals
20、in the annex. This alphanumeric designa-tion is the first three digits of the chemical resistance cell.8.1.2 The concentration of the chemical from row two ofTable 1 is designated as the fourth digit of the chemicalresistance cell.8.1.3 The test temperature from row three of Table 1 isdesignated as
21、the fifth number of the chemical resistance cell.8.1.4 The resistance of a compound from row four of Table1 is designated as the sixth number of the chemical resistancecell.
