conditions for inspection and delivery.
6.1.1 Chemical analysis
Samples fo chemical analysis shall be taken at the time of casting according to EN 14361. Their shape and conditions of pcoduction (mould design, cooling rate, mass. etc.) shall be designed, such that they represent the average composition of the liquid metal, and be suitable for the method of analysis. The analytical procedure shall be taken into account.
6.1.2 Test pieces for mechanical testing
6.1.2.1 Identification of test pieces
Each test pieces shall be marked in such a manner that, after removal, it is always possible to identify the product from which it is taken and its location. If, during the course of subsequent operations, removal of the markings cannot be avoided, new markings o labels shall be made before the originals are removed.
6.1.2.2 Preparation of test pieces
Test pieces shall be taken from the sample after completion of all the mechanical and heat-treatments that the product has to undergo before delivery, and which can influence the mechanical properties of the metal. In cases where this is not possible, the test pieces can be taken at an earlier stage, but they shall be subjected to the same treatment as that to which it is intended to submit the product concerned1).
Cutting shall be carried out in such a manner that it does not change the characteristics of the part of the sample from which the test pieces are to be prepared, Thus, the dimensions of the samples shall provide an adequate machining allowance to permit removal of the zone affected by cutting.
Samples shall not be machined or treated in any way by which their mechanical properties can be altered. Any straightening required shall be carried out with great care, preferably by hand.
6.1.3 Test-pieces for tensile test
6.1.3.1 Identification of test pieces
Each test piece shall be marked in such manner so that It is possible to identify the inspection lot from which It was taken.
If a test piece is marked by stamping, this shall not be in a place or manner which can interfere with subsequent testing.
NOTE Where it is not convenient to mark a test psece, an identification label can be attached.
6.1.3.2 Number of test pieces
One test piece shall be taken from each sample.
6.1.3.3 Type and location of test pieces
The un-machined wire shall be considered as the test piece.
6.2 Methods of tests
6.2.1 Chemical composition
Methods of analysis shall be at the discretion of the manufacturer. In case of dispute concerning the chemical composition, referee analysis shall be carried out by the methods specified in the relevant European Standard (see EN 14242 and EN 14726) and the results obtained by this method shall be accepted.
6.2.2 Tensile test
The tensile test shall be carried out in accordance with EN 10002-1.
6.2.3 Measurement of dimensions
All dimensions shall be checked at the ambient temperature of the workshop or laboratory. and in case of dispute, at a temperature between 15 C and 25 C.
6.2.4 Surface finish
Unless otherwise specified, examination of surface appearance shall be carried out before delivery without the
assistance of magnifying apparatus.
6.2.5 Other tests
If other mechanical or physical tests are required, these shall be agreed between manufacturer and purchaser. These tests shall be carried out either in accordance with the existing European or International Standards (for example EN ISO 6507-1, EN ISO 7438, ISO 7800, ISO 7801. ISO 7802).
6.3 Retests
6.3.1 Mechanical properties
If any of the test pieces first selected fails to meet the requirements for the mechanical test, the following procedure shall be applied:
— if an error is clearly identified, either in the test piece preparation or in the test procedure, the corresponding results shall be disregarded and the testing resumed as initially required;
— If an error is not clearly Identified then two further specimens shall be taken, one from a different coil (or reel or bundle etc.) of the same lot if avaiLable, one from the same coil from which the original specimen was taken, unless that coil has been withdrawn by the manufacturer;
— if both test pieces from these additional specimens meet the requirements, the lot which they represent shall be deemed to conform this European Standard.
Should one test piece fail:
— the lot shall be deemed not to conform to this European Standard; or
where applicable, the lot can be submitted to additional treatment(s) and then retested as a new lot.
6.3.2 Other properties
The same procedure shall apply to other properties unless otherwise agreed between manufacturer and purchaser.
