3.1.2 The supplier must ensure that the delivery section steel complies with the
requirements of this Standard; the purchaser is entitled to conduct inspection and
acceptance according to the provisions of the corresponding standards.
3.1.3 The purchaser shall conduct inspection for the length, weight and per bundle
number of section steel according to markings of each bundle of section steel before
dismantling it; those with quality discrepancy shall not be dismantled.

the bundle-batch rules shall be in accordance with those specified in the
corresponding standards.
3.3 Sampling quantity and sampling location

3.4 Re-examination and decision rules
3.4.1 If the failed results are obtained from the test, and when only a single value may
be provided (for example, tensile test and bending test), the following methods shall
be adopted.
a) When the test unit is a single product, the same type of double-quantity test shall
be made for the disqualified item; for double-quantity test, all items shall be
qualified; otherwise, the product shall be rejected;
b) When the test unit is not a single product, unless otherwise agreed, the supplier
may either pick out the sample products from the test unit, or not pick out.
1) If the sample product is not picked out from the test unit, double-quantity of
samples shall be taken from the same bundle of products for the
re-examination of those disqualified items. The re-examination results shall
all be qualified.
2) If the sample product is picked out from the test unit, another two sample
products shall be selected from the same test unit randomly; then, test
specimens shall be prepared from the two sample products respectively.
Repeat the same kind of test under the same condition as the first test; the
testing results shall all be qualified.
c) When the products delivered in rolls are disqualified during the re-examination
process, that bundle of product may be inspected one-by-one; the qualified
product is allowed to be delivered.
3.4.2 When the testing results obtained by sequential method are disqualified, such
as impact test, it shall be determined in accordance with the requirements of 8.3.4.3.3
