4.5 Criteria of impact test results

4.6 Rules for retest and determination

4.6.1 Sequential test (such as impact test)

In accordance with the criteria of impact test results specified in 4.5, when the results are unacceptable, the sample products of the unacceptable test results shall be picked out and scrapped, two samples products are taken from the rest of the test unit and a new group of three test pieces are taken from each sample product. All the test results of the two groups of test pieces shall be acceptable; or else, the test unit shall be rejected.

4.6.2 Non-sequential test (such as tensile test and bending test)

4.6.2.1 If the unacceptable results are not calculated from the mean value but are measured from the tests, such as tensile test and bending test, the following method shall be used.

4.6.2.2 When the products' retest results are unacceptable, the testing on each products of the test unit is allowed and the delivery of acceptable single-piece products is allowed.

4.6.3 Unallowed retest item

In case of any flake, retest is not allowed.

5.1 General specifications

5.1.1 The section steels in bundles shall kept flush at both end.

5.2 Packaging materials

5.2.1 The section steels in bundles shall be strapped securely using strapping materials.

5.2.2 In accordance with the requirements of the purchaser, protective materials for strapping may be used between section steels and between section steels and strapping materials, in order to protect section steels from being damaged and strapping materials from being cut off.

5.2.3 In accordance with the requirements of the purchaser, protective packaging materials may be used for packaging. The commonly-used protective materials include kraft paper, volatile rust preventive paper, plastic film, grease-proof paper and so on.

5.3 Strapping package

5.3.1 Hot-rolled section steels
