Note:
D Others includes listed elements for which no
specific limit is shown as well as unlisted metallic elements. The
producer may analyze samples for trace elements not specified in the
specification. However, such analysis is not required and may not
cover all metallic Others elements. Should any analysis by the
producer or the purchaser establish that an Others element exceeds the
limit of Each or that the aggregate of several Others elements exceeds
the limit of Total, the material shall be considered nonconforming.
E Other Elements—Total shall be the sum of
unspecified metallic elements 0.010 % or more, rounded to the second
decimal before determining the sum.
F The aluminum content shall be calculated by
subtracting from 100.00 % the sum of all metallic elements present in
amounts of 0.010 % or more each, rounded to the second decimal before
determining the sum.
