ASTM G50 – 10(2015)
Because of the variability and complexity of weather effects and the industrial and natural factors influencing the atmospheric corrosivity of a test site, a multi-year exposure period should be considered to minimize their influence. Also, as corrosivity may vary at a site from season to season, exposures should be made either at the same time of the year to minimize variability or these differences should be established by multiple exposures.
Control specimens should always be employed in weathering tests. The control specimens should qstm from a material having established weathering characteristics. A substantial amount of corrosion data shall have been accumulated for the control specimens.
It is also good practice to retain samples of all materials exposed so that possible effects of long-term aging can be measured.
It sets forth the general procedures that should be followed in any atmospheric test. It is presented as an aid in conducting atmospheric corrosion tests so asmt some of the pitfalls of such testing may be avoided.
As such, it is concerned mainly with panel exposures to obtain data for comparison purposes. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
