ISO 377:2013 pdf download.Steel and steel products – Location and preparation of samples and test pieces for mechanical testing.
ISO 377 specifies requirements for the identification, location and preparation of samples and test pieces intended for mechanical tests on steel sections, bars, rod, flat products and tubular products as defined in ISO 6929. If agreed in the order, ISO 377 can also apply to other metallic products. These samples and test pieces are for use in tests that are carried out in conformity with the methods specified in the product or material standard or, in the absence of this, in the standard for the test method.
Where the requirements of the order or product standard differ from those given in this International Standard, then the requirements of the order or product standard apply.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6929 and the following apply.
3.1
test unit
number of pieces or the tonnage of products to accept or reject together, on the basis of the verification tests carried out on sample products in accordance with the requirements of the product standard or order
Note 1 to entry: See Figure 1.
3.2
sample product
item (e.g. bar, sheet, coil) selected for inspection or testing
Note 1 to entry: See Figure 1.
3.3
sample
sufficient quantity of material taken from the sample product for the purpose of producing one or more test pieces
Note 1 to entry: See Figure 1.
Note 2 to entry: In certain cases, the sample can be the sample product.
3.4
rough specimen
part of a sample having undergone mechanical treatment, for the purpose of producing a test piece
Note 1 to entry: See Figure 1.
3.5
test piece
part of a sample or rough specimen, with specified dimensions, machined or unmachined, brought to a required condition for submission to a given verification test
Note ito entry: See Figure 1.
Note 2 to entry: In certain cases, the test piece can be the sample or the rough specimen.
3.6
reference condition
condition of a sample, rough specimen or test piece having undergone a heat treatment to represent the intended final condition of the product
Note 1 to entry: In such cases, the sample, rough specimen or test piece is called the reference sample, reference rough specimen or reference test piece.
4 General requirements
4.1 Representative testing
Sample, rough specimens and test pieces selected in accordance with Annex A shall be considered to be representative of the product.
NOTE As a result of their production sequence, e.g. melting, casting hot or cold forming or both, heat treatment etc., steel products are not homogeneous. The mechanical properties of samples taken from other locations can be different.
