NOTE If the product standard specifies the determination of percentage elongation after fracture for a given gauge 1000-1, the extensometer gauge length should be equal to this length. In general, the diameter of the parallel length of machined cylindrical test pieces shall be not less than 4 mm.
Worldwide Standards We can source any standard from anywhere in the world.
It is the constant aim of BSI to improve the quality of our products and services. It is incorporated by Royal Charter. Search all products by.
Revisions British 110002-1 are updated by amendment or revision.
Method of test at ambient temperature Status: In principle, it will be necessary to determine any materials strain rate response before the total uncertainty budget can be calculated. Since the equivalent tolerances, a, are based on measured data, bz a simple least mean squares fit to the data, it is necessary to decide what distribution model of the uncertainties is appropriate in accordance with the GUM. The methods based on the calculation of the characteristics of a sliding segment are the most convenient.
They should be given in basic Sl units relating to the force, the extension, the time and the 1000-21 piece dimensions. Method of test at ambient temperature.
BS EN 10002-1:2001
In the case of non-proportional test pieces, the symbol A should be supplemented by an index indicating the original gauge length used, expressed in millimetres, for example: The latter is obtained by dividing this force by the original cross-sectional area of the test piece So see Figure 6. The method used should be verifiable. Parts 3 and 4 will be replaced by corresponding ISO standards.
A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official versions.

ENMetallic materials – Tensile testing – Part 4: Hence it is necessary to have a prior knowledge of a material’s tensile response to strain or stress rate before being able to calculate the measurement uncertainty. The longitudinal strip is generally used for tubes with a wall thickness of more than 0,5 mm.
Specimens are gripped ensuring that the specimen is aligned axially to minimize bending. Some limited data and the following examples may be used to estimate uncertainty for some classes of ne.
The difference between the area Su and the original cross section So expressed as a percentage of the original area gives the percentage reduction of area. Figure 11 – Proportional 01002-1 pieces see annex D Be ce ns ed C op y: Figure 1 – Definitions of elongation Li ce ns ed C op y: NOTE 2 In case where the machine is operating in strain rate control, the stress rate should be calculated taking into 1002-1 the modulus em elasticity of the material.
It is the intention, based on further developments by manufacturers and users that annex A will become normative in the next revision of this standard. 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. It is a comprehensive document of over 90 pages based upon rigorous statistical methods for the summation of uncertainties from various sources.
Figure 8 – Maximum force Fm Li ce ns ed C op y: Within the plastic range and up to the proof strength non-proportional extension or total extension the strain rate shall not exceed 0, 5 s Data which are derived directly from the machine transducers or amplifiers should be collected and processed using equipment with frequency band width, sampling frequency and uncertainty at least equal to those used to provide the machine computer calculated results.

A distinction is made between: Typical results from various intercomparison exercises are given in J. Your basket is empty. Various BSI electronic information services are also available which give details on all its products and services.
Special precautions shall be taken to ensure proper contact between the broken parts of the test piece when measuring the final sn length.

The cross-section of the test piece may be circular, square, rectangular or, in special cases, of another shape. Products that may be tested in accordance with this standard include metallic sheets and plates, wire, bar or section, and tubes. The original gauge length shall be not less than 20 mm. The nominal width of the test piece may be used, provided that the machining tolerances and tolerances on shape given in Table B.
