ISO 9016-2012 pdf free download.Destructive tests on welds in metallic materials – Impact tests – Test specimen location, notch orientation and examination.
ISO 9016 specifies mainly the method to be used when describing test specimen location and notch orientation for the testing and reporting of impact tests on welded butt joints.
This International Standard applies to impact tests on metallic materials in all forms of product made by any fusion welding process.
It is used in addition to ISO 148 (all parts) and includes test specimen denomination and additional reporting requirements.
2 Normative reference
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 148-1. Metallic materials — Charpy pendulum impact test — Part 1: Test method
3 Principle
Impact testing shall be in accordance with ISO 148-1. The test temperature, location, type and size of test specimen, and notch orientation shall be in accordance with the relevant application standard.
In addition to the requirements of ISO 148-1, the notch position may be located by macroetching.
4 Method of denomination
4.1 Lettering system
The denomination is based on a lettering system to describe the type, location and notch orientation and a numbering system to show the distance (in millimetres) of the notch from reference lines (RL). The method of denomination Is shown in Tables 1 and 2. The test specimen shall be taken from the welded joint such that its longitudinal axes are at right angles to the weld length.
4.2 Characters
The denomination comprises the following characters:
— 1st character U: Charpy U- notch.
V: Charpy V-notch.
— 2nd character W: notch in the weld metal; the reference line Is the centre line of the weld at the position of the test specimen.
H: notch in the heat affected zone; the reference line is the fusion or the joint line(notch will include HAZ).
4.3 Additional information
In cases where this simple denomination does not sufficiently define the location or notch orientation, a sketch referring to the weld procedure should be provided.
5 Examples of denomination
Examples of denomination are given in Tables 1 and 2 and Figure 1.
6 Examination
The test specimens designated by this International Standard shallbe tested in accordance with ISO 148-1.
7 Test report
The test report shall include the following information in addition to that given in ISO 148-1:
a] reference to this International Standard, i.e. ISO 9016;
b) test specimen denomination;
c} sketch if required;
d) type and dimensions of imperfections observed;
e) other information as required by the application standard and/or by agreement between the contracting parties.
An example of a typical test report is given in Annex A.ISO 9016 pdf download.
