ASTM-D7584 2015

1.1 This environmental chamber method measures the resistance of the treated wet blue to the germination of spores and subsequent vegetative growth over a period of four weeks. The test method is useful in estimating the performance of fungicides and should assist in the prediction of storage time of wet blue before fungal growth begins. The apparatus is designed so it can be easily built or obtained by any interested party and duplicate the natural environment in which wet blue is inoculated with fungal spores. Spores that germinate on untreated or treated wet blue can produce fungal growth, resulting in disfigurement or discoloration, or both, of the wet blue.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
