Corrosion testing is often done by using ASTM B117. Corrosion is the gradual destruction of materials, (usually metals), by chemical reaction with its environment. Corrosion degrades the useful properties of materials and structures, including strength, appearance and permeability to liquids and gases.

1. ASTM Testing
Micom offers a wide range of ASTM testing services
including the ASTM B117 test. ASTM Standards
(American Society for Testing and Materials) cover a
wide range of test methods, practices and material
specifications. Many of these test methods are product
specific or test specific. You will find a partial list of the
test methods we can do in the navigation bar to the right of this page.
Practices are more general in nature and are often called upon by test
methods or standards other than ASTM. For example, ASTM G155 is a
practice for Xenon Arc accelerated exposure. You can test a product based on
that practice, but you are missing specific test parameters such as irradiance,
test duration and pass/fail criteria (e.g. color change, gloss, haze, etc.). This
affects the lab’s ability to know exactly what needs to be done. These missing
parameters will be found either in purchasing specifications, technical
specifications or other standards calling upon one or more practices and test
methods, such as ASTM G154 for accelerated weathering, that are used to
carry out testing. Once the testing is complete, compliance can be established
based on the product-specific standards/documents.
As an example: you need to do a UV testing evaluation to validate a new
coating you want to use on an outdoor terminal box. A proper way to specify
your testing using ASTM test methods might be:
Test samples as per ASTM G155, Cycle 1 (there are many cycles that will
give you different test results)
2000 hours exposure
Before and after exposure, measure the coating’s gloss at 60o, as per
ASTM D523.
Gloss difference shall not be more than 10 units

2. Whether you want to validate your products using ASTM
tests or any other standard/specification, working your
way through standards can be a tedious process. Our
experts will be happy to assist you in preparing a test plan
that works for you and gives you real answers.
