ASTM B117:2011, “Standard Practice for Operating Salt Spray (Fog) Apparatus,” has just been released. The 12 page standard is also available in a redline edition, which means that when you purchase the copyright document, you not only get the new edition, but also a copy of the previous 2009 Edition with all the corrections “redlined.”
One of the first standards to catch my interest, ASTM B117 is the oldest (originally issued in 1937) and most widely used cabinet test. It’s used primarily to compare the corrosion resistance of painted or metal coated samples.
ASTM B117 covers the apparatus, procedure, and conditions required to create and maintain the salt spray (fog) test environment. It provides a controlled corrosive environment which has been utilized to produce relative corrosion resistance information for specimens of metals and coated metals.
The reproducibility of results in the salt spray exposure is highly dependent on the type of specimens tested and the evaluation criteria selected, as well as the control of the operating variables. In any testing program, sufficient replicates should be included to establish the variability of the results.
Variability has been observed when similar specimens are tested in different fog chambers even though the testing conditions are nominally similar and within the ranges specified in the practice.
ASTM standards, both current and obsolete, are available from Document Center Inc. at our website, www.document-center.com. Use our website to view the history of the standard as well, with more detail available than even at the ASTM International site. Or contact us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com). We’re happy to assist you with your standards needs.
Please let me know the important changes (other than the editorial changes) happened in ASTM B117 since 1992 to 2011. Do any one of these changes can affect the final outcome of the result?
Thanks in Advance.

Hi Anirban:
Thanks so much for asking.
The ASTM B117 has gone through 9 revision cycles since 1992. I would suggest that the best approach for you will be to take your 1990 Edition and compare it to the current 2011 Edition. Of course, there are red-line editions available for this standard for the last couple of updates. But since there’s so many updates during the period you’re interested in, probably a direct review will be your best bet.
If you need a copy of the 1990 Edition or the current 2011 Edition, we’ve got both in stock. Just let us know and we’ll get you a quote for your review.
Thanks!
Claudia
