10、Method: 3 test specimens approximately 25 x 190 mm are cut from sample sheets. Specimens from finished gaskets may differ in width and length and should not include bolt holes. These specimens are preconditioned in a controlled humidity room (or in a closed chamber with gentle mechanical circulation

11、 of the air) for 70 h minimum at 21 to 29 C and 50 + 5% R.H. Specimens are then measured for original length. Expose vertically hung test specimens in a controlled temperature and humidity chamber for 7 days at 38 C and 95-100% R.H., followed by 7 days at 38 C and 15-20% R.H. Length of test specimen

12、s is measured after each of these two 7-day exposure periods. Average % change in length after each exposure is calculated, based on the original lengths previously determined. Permissible dimensional changes are as follows: A2 A3 After 7 days At 38 C and 95-100% R.H., % 0 to +4.2 +1.0 to +4.8 At 38
