- Abstract
- In 1959 a new requirement was introduced in the ASTM standard on fire tests of building constructions, according to which a specimen cannot be subjected to fire test until its maximum "dampness" becomes lower than 75 per cent, in terms of relative humidity. Although in its present form, this "moisture requirement" is still rather vague, the realization that moisture, inevitably present in almost any building material, offers a serious problem to the reproducibility of fire test results and that more refined techniques should be used for its measurement and control, should be regarded as a very important step in the right direction.
