VICTORIAN TESTING and INSPECTION SERVICES GENERAL TERMS, CONDITIONS and ABBREVIATIONS

1. Test certificates may not be published in part or in full unless written permission has been obtained from VTS.

2. The test methods used for the determination of results quoted in this test certificate are unless otherwise qualified in accordance with the quoted specifications. In general it is intended that both application test method specifications shall be quoted. However where no ambiguity exists, and where a number of test method specifications are referenced by the application specification, then only the application specification might be quoted.

3. General terminology and abbreviations are in accordance with Australian Standards.

4. Charpy V-notch impact tests are performed in accordance with ASTM E23 which has slight differences in machine configuration and more stringent performance requirements than Australian Standards. Tests performed in accordance with ASTM E23 in certain circumstances are accepted by Australian Standards as conforming to AS 1544-2

5. The test material may be indicated by a prefix code letter in the test piece identification. The most common abbreviations are:-

W – Weld metal
P – Parent metal
F – Fusion line
H – Heat affected zone
J – Joint
F + (mm) – distance from F

6. The orientation of test pieces with respect to the product from which they are prepared may be indicated by code letters in the test piece identification following the test material prefix. The meaning of those code letters shall be as follows:

Note: The principal axis of product is the rolling or extrusion direction for wrought products. For other products where no clear differentiation exists, the principal axis shall be that with the maximum length.

Examples: A Charpy test piece with the principal axis of the test piece parallel to the rolling direction of an un-welded plate and notched in the conventional manner so that the line of the notch tip is perpendicular to the plate surface shall be designated LT since the direction of the notch is parallel with the width (transverse) axis of the product.

7. The position of test pieces within the thickness may be indicated by a suffix letter following the orientation code. The meaning of the suffix letters shall be:

A – in welded joints the face side (see AS 2205.1)

B – the side opposite side A

M – mid-thickness

In un-welded material, the A or B position coding will usually be arbitrarily assigned.

Examples:

(1) A Charpy test piece cut from mid-thickness weld metal in a circumferential weld in pipe, will be identified WTLM

(2) An all-weld metal tensile test piece prepared from the A side of the weld in a rectangular test plate will be identified WLA

8. The code designation system is as follows:

9. Unless otherwise stated all specifications shall be the current edition as amended where appropriated.

10. This certificate is produced without erasures or alterations unless initialled by the signing officer.

11. Whilst every care is taken by us in furnishing the results contained herein, we must expressly disclaim liability for any claims for damages of whatever nature arising out of any inaccuracies contained herein.

12. Non Destructive Testing Imperfection Terms as per AS 4749.
