This standard specifies the test methods for hot air aging, ozone aging and artificial weathering accelerated aging (xenon arc lamp, carbon lamp and UV fluorescence lamp).

This standard is applicable to the comparison between the aging-resistant performance of pitch-based rolls and paints, high polymer rolls and paints used for building water proofing work. Other building water proofing materials may also adopt by reference.
