Active view current version of standard. Where appropriate, it is recommended that astm e617 International Recommendations be used. Note-Although metric weights are almost exclusively used in laboratories, tolerances are given in this specification asym nonmetric weights in U.
ASTM does not give any warranty astj or implied or make any representation that the contents of this abstract are accurate, complete or up to date. It is anticipated that as metrication, even astm e617 test laboratories, proceeds further, the nonmetric tables given in this specification will become obsolete.
