Specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occuring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the applicaton of the specified treatments. Test conditions are only given for open cellylar latex, both open- and cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials will be added as required. The effect of the ageing procedures of any of the physical properties of the material may be examined, but those normally tested are either the elongation and tensile properties, or the compression or identation hardness properties. These tests do not necessarily correlate either with service behaviour or with ageing by exposure to light.
