5 Inspection Rules
5.1 Inspection and acceptance
5.1.1 Products shall be inspected by the supplier to ensure the quality is as specified
number for each batch of plates and sheets, but not less than two sheets;
take one sample by cutting from each sheet sampled.
Appearance quality Conduct inspection on each sheet (or roll) 3.6 4.5
5.6 Judgement of inspection results
5.6.1 When the chemical composition of any sample is unacceptable and the
smelting batch can be differentiated, then the smelting batch represented by the
sample is unacceptable; and the other smelting batches are subjected to inspection in
sequence, which will be delivered if they pass the inspection. When smelting batches
are unable to be differentiated, then the lot is judged to be unacceptable.
batch is judged to be unacceptable. But inspection on each sheet for plates and sheets
is allowed, and those passing the inspection are delivered.
5.6.3 When the room-temperature tensile properties of any sample are unacceptable,
then take separately a double number of samples from the batch (or furnace) to repeat
the test. If all the results of the repeated test are acceptable, then the batch (or furnace)
of products are acceptable. If there is any result of the repeated test still unacceptable,
then the batch (or furnace) of products are judged to be unacceptable. When the
inspection by the supplier on each sheet (or roll) is allowed as agreed on by the supplier
and the purchaser, those passing the inspection are delivered.
5.6.5 When the appearance quality is unacceptable, then the sheet (or roll) is judged
to be unacceptable, take separately a double number of samples from the batch (or
furnace) of products to repeat the test. If all the results of the repeated test are
acceptable, then the batch (or furnace) of products are acceptable. If there is any result
of the repeated test still unacceptable, then the batch (or furnace) of products are
judged to be unacceptable. When the inspection by the supplier on each sheet (or roll)
is allowed as agreed on by the supplier and the purchaser, those passing the
inspection are delivered.
