NOTE 2 In case where the machine is operating in strain 10020-1 control, the stress rate should be calculated taking into account the modulus of elasticity of the material.
The internationally adopted value for k is 5, If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. The point at which this line intersects the curve gives the force corresponding to the desired proof strength. Contact the Information Centre. 110002-1 a pair of needle-pointed dividers set at the gauge length, an arc is scribed with the mark as a centre. A single copy of this British Standard is licensed to edtBS: Compliance with a British Standard does not of itself confer immunity from legal obligations.
The b transition radius between the grips ends and the parallel length shall be: Description Literature Contact Us This European standard specifies the method for tensile testing of metallic materials and defines the mechanical properties that can be determined at ambient temperature. BSI also ns the copyright, in the UK, of the publications of the international standardization bodies.
An approach for estimating the uncertainty of measurement using the “error budget” concept based upon the tolerances specified in the testing and calibration standards has been presented elsewhere  and was subsequently expanded to form the basis of the annex J of ISO . Some limited data and the following examples may be used to estimate uncertainty for some classes of materials.
After determining ReL by this procedure, the test rate may be increased as per Software for Series Systems. NOTE Comparisons of percentage elongation are possible only when the gauge length or extensometer gauge length, the een and area of the cross-section are the same or when the coefficient of proportionality k is the same. A type B evaluation is based on some other means ; Thus the use of tolerances specified in a standard comes under hs type B category.
If permission is granted, the terms may include royalty payments or a licensing agreement.
If the material tested has no yield phenomena, the proof strength Rp0,2 should be used. This is particularly important in the case of test pieces of small cross-section and test pieces having low elongation values.
Search all products by. It supersedes BS EN They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Prior to the test a very small mark should be made near one of the ends of the parallel length. In the case of parallel side test pieces less than 20 mm wide, and unless otherwise specified in the product standard, the original gauge length Lo shall be equal to 50 mm.
If this rate cannot be regulated directly, it shall be fixed by regulating the stress rate just before yield begins, the controls of the machine not being further adjusted until completion of yield.
For the purposes of assessing the acceptability of such differences, five similar test pieces should be tested and the average difference for each relevant property should lie within the limits shown in Table A. The parallel length Lc or, in the case where the test piece has no transition curve, the free length between the grips, shall always be greater than the original gauge length Lo.

This annex has now been revised to more closely follow the approach for estimating the uncertainty of measurement outlined in the guide established by Rn TAG4 . It is the constant bd of BSI to improve the quality of our products and services.
Machined transverse, longitudinal and circular cross-section test pieces are described in annex B for tube wall thickness less than 3 mm and in annex D for thickness equal to or greater than 3 mm. The test pieces are defined according to the shape and type of product tested.
EN 10002-1 Tensile Testing Metallic Materials
In the case of length of tube, the original cross-sectional area So shall be calculated as follows: Figure 12 – Test pieces comprising a length of tube see annex E Li ce ns ed C op y: In the case of non-proportional test pieces, the original gauge length Lo is taken independently of the original cross-sectional area So. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Management Centre or to any CEN member.
Therefore for stainless steel, the combined standard uncertainty of Rp0,2 is given by: WaveMatrix 2 for Dynamic Testing. Results determined typically include yield and proof strengths, ultimate tensile strength, and elongation at fracture.

The original gauge length shall be not less than 20 mm. Please confirm that you agree with our privacy and cookies policy to submit this form. When this procedure is used, it should be recorded in the test report.
In general, the diameter of the parallel length of machined cylindrical test pieces shall be not less than 4 mm. A method which may be used is to construct the line parallel to that determined by the hysteresis loop so that it is tangent to the force-extension curve. A second arc of the same radius should then be scribed from the original center, and the distance between the two scratches measured by means of a measuring microscope or other suitable instrument.

Alternatively, it is recommended that “in-house” test pieces are tested for quality control bw see . Date Comments Li ce ns ed C op y: For very thin materials, it is recommended that strips of identical widths should be cut and assembled into a bundle with intermediate layers of a paper which is resistant to the cutting oil.
In ns of dispute, the value, D, shall be used, as long as there is sufficient material. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting:
