B4.3 Age the seals for 504 h at 125 1 C. B4.4 Remove the specimens from the test tubes and immediately place them on a clean absorbent pad
45、 or laboratory grade paper towels and cover with the same material. Cool to room temperature at least 30 minutes before working with the elastomer. Final measurements must be taken within 120 minutes of the end of B4.3. B4.5 Wipe specimens dry with a clean, lint free, laboratory grade paper towel or
46、 equivalent. B4.6 Determine the final volume, tensile strength, elongation, and Durometer readings of each specimen as described in B4.1. B5 Test Results B5.1 Report the percent volume change, percent tensile change, percent elongation change, and points Durometer A hardness change for each test spe
