this sample is determined unqualified. Other furnace batches shall be inspected in turn,
and delivery the qualified products. If the furnace batch of products cannot be
distinguished, then this batch is determined unqualified.
6.6.2 When the prohibited substances of any of the samples is unqualified, and if the
furnace batch of products can be distinguished, then the furnace batch represented by
this sample is determined unqualified. Other furnace batches shall be inspected in turn,
and delivery the qualified products. If the furnace batch of products cannot be
distinguished, then this batch is determined unqualified.
6.6.3 When the dimension deviation of any of the plates/sheets is unqualified, this
batch of products are determined unqualified. Agreed upon by both supply and
demand parties, it is allowed to inspect piece by piece, and delivery the qualified
products. When the dimension deviation of any of the strips is unqualified, this roll is
determined unqualified.
