ASTM International has reissued its standard guide for testing industrial protective coatings, with editorial changes.
D6577 - Standard Guide for Testing Industrial Protective Coatings, developed by Committee D01.46 on Industrial Protective Coatings, is available as D6577-06(2011)e1.
Selecting, Using Test Methods
This guide covers the selection and use of methods and procedures for testing industrial protective coatings, in order to evaluate the general performance level to be expected of a coating or coating system on a given substrate exposed to a given type of environment.
|The standard, revised for editorial changes, was last updated in 2006.|
The guide also covers the testing of liquid coatings as applied by means appropriate to the coating and circumstance.
Selection of the standards to be followed must be governed by experience and the requirements in each individual case, together with agreement between the supplier and the user.
Results obtained in the tests cited in this guide may not be adequate for predicting the service life of a specific coating system in a specific environmental exposure, ASTM notes. A control system of known performance in the service environment should be included in the testing for comparison.
ASTM also cautions that surface preparation or cleanliness before coating application can be critical to coating performance.
The standard, last revised in 2006, has been the subject of some editorial changes. Unlike technical changes, editorial changes do not require balloting.
In general, editorial changes may include reordering of sections; updating footnotes or titles in referenced documents; changing titles in sections, tables or figures; and correcting errors in formatting and typesetting.
In the case of the D6577 revision, the editorial changes involved the removal of several withdrawn standards in Section 2-Referenced Documents and throughout the text, an ASTM spokeswoman said.
The standard is part of ASTM Volume 06.02 Paint -- Products and Applications; Protective Coatings; Pipeline Coatings, which covers traffic, marine and industrial protective coatings as well as masonry treatments and architectural finishes and paint products.
The standards include paint applications in factories, coil coal metal, coatings on preformed products, and paint application tools; tests for applying and evaluating protective coatings and linings in power generation facilities; and standards on the durability of pipeline coatings and linings.
