Active Standard: A487 / A487M - 93(2012)
In order to reflect current production capabilities, a reduction in the maximum limits of sulfur and phosphorous are proposed. The reductions proposed are in accordance with similar reductions implemented in the revisions of ASTM A216 that were approved in 2012. This change would have the incidental effect of aligning the ASTM specification more closely to other worldwide specifications for similar materials.
