Standard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride Solution

ASTM standard that contains six procedures (identified as Methods A, B, C, D, E and F), that are used for the determination of the resistance of stainless steels and related alloys to pitting and crevice corrosion when exposed to oxidizing chloride environments. These tests may be used to determine the effects of alloying additives, heat treatment, and surface finishes on pitting and crevice corrosion resistance.

Standard Test Methods for Measuring Adhesion by Tape Test

This 8 page standard was published on Jun 22, 2009 by American Society for Testing and Materials.

It describes two procedures for assessment of adhesion of coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film. While test method A is more suitable to be performed at job site, method B is good for lab use.

These test methods are used to establish whether the adhesion of a coating to a substrate is at a generally adequate level. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.

Note 3 – It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the same inherent adhesion.

This test method is similar in content (but not technically equivalent) to ISO 2409.

In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrate is not determined.

The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

This standard does not purport to address 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.

Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference

This test method is a standard procedure for determining the resistance to water penetration under uniform static air pressure differences. The air-pressure differences acting across a building envelope vary greatly. These factors should be fully considered prior to specifying the test pressure difference to be used.

Standard was published on March 1 by ASTM International.
