The test uses live cultures of fungal organisms that require careful colonization, storage, and feeding to remain viable strains. This assumption may lead to weight loss that is not due to decay. The resistance level is determined by the physical appearance and the severity of the cracks on the surface of the material sample. The test method assumes that the test blocks exposed to certain conditions after treatment will achieve equilibrium, and will return to the same equilibrium after exposure to fungi. The test methods outlined in this standard are used to evaluate the resistance of rubber materials when exposed to varying degrees of ozone.

The sections on Treatment and Preservative Permanence are referenced by other ASTM standards. The results are used to facilitate target retentions in subsequent tests for effectiveness against termites (see Test Method D 3345 ) and in field stakes (see Test Method D 1758 ). This test method is useful in the development of new wood preservatives and preservative systems by evaluating the minimum preservative retention to prevent decay under laboratory conditions. As you’ll learn in this article, ASTM D2000 provides buyers with a common language. Published by ASTM International and designed for automotive applications, this classification system is used by many other industries because it’s clear, concise, and highly descriptive.

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. ASTM D2000 is an industry specification that provides buyers and suppliers with a standard way to describe rubber. Handling Test Blocks After Exposure to Test Fungiġ.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. Stabilization of Treated Test Blocks and Placement in Culture Bottles Preparation and Impregnation of Test Blocks 1.1 This test method covers determination of the minimum amount of preservative that prevents decay of selected species of wood by selected fungi under optimum laboratory conditions.ġ.2 The requirements for preparation of the material for testing and the test procedure appear in the following order:
