Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More D The choice of types and concentrations of reagents, duration of immersion or stress, or both, level of stress, temperature of the test, and properties to be reported are necessarily arbitrary. The specification of these conditions provides a basis for standardization and serves as a guide to investigators wishing to compare the relative resistance of various plastics to chemical reagents.

For applications involving continuous immersion, the data obtained in short-time tests are of interest only in eliminating the most unsuitable materials or indicating a probable relative order of resistance to chemical reagents. Base the selection of test conditions on the manner and duration of contact with reagents, the temperature of the system, applied stress, and other performance factors involved in the particular application.

These practices can be extended to such applications with specifics on the study conducted noted in the report. Particular attention should be given to the variability in the data generated, especially for the baseline controls, and issues in data generation reported to mitigate misuse of information. These practices include provisions for reporting changes in weight, dimensions, appearance, color, strength, and other mechanical properties.

Standard reagents are specified to establish results on a comparable basis without precluding the use of other chemical reagents pertinent to specific chemical resistance requirements.

Provisions are made for various exposure times, stress conditions, and exposure to reagents at elevated temperatures. The type of conditioning immersion or wet patch depends upon the end-use of the material. If the material is used as a container or transfer line, immersion of the specimens is used. If the material will only see short exposures or will be used in proximity and reagent will splash or spill on the material, the wet patch method of applying reagent to the material is used.

Practice B differs from Test Method D , which seeks to quantify the susceptibility of ethylene plastics to environmental stress-cracking subjected to specific conditions, by measuring the proportion of specimens that crack in a given time. The values given in parentheses are for information only. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Specific hazards statements are given in Section 7. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Scope 1.
