These tolerances are applicable if the nominal value of the original cross-sectional area So is to be included in the calculation without having to measure it.
A single copy of this British Standard is licensed to edtBS: For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
Complementary recommendations for computer controlled testing machines are indicated in the informative annex A to this standard. In some cases, it may be helpful to draw, on the surface of the test piece, a line parallel to the longitudinal axis, along which the gauge lengths are marked.
A statistical approach to the analysis of intercomparison exercises Round Robin experiments does not separate out the two contributing causes of the scatter but nevertheless gives a useful indication of the likely range of tensile results measured by different laboratories using similar material. After determining ReL by this procedure, the test rate may be increased as per The point at which this line intersects the curve gives the force corresponding to the desired proof strength non-proportional extension.
Customers who bought this product also bought BS EN This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Januaryand conflicting national standards shall be withdrawn at the latest by January In addition, there are other factors that can affect the measurement of tensile properties such as test piece bending, methods of gripping the test piece, or the testing machine control mode, i.
These data should be revised if the machine is modified. NOTE 1 A three-degree polynomial regression is recommended. Every endeavour should be made to ensure that test pieces are held in such a way that dn tension is applied as axially as possible, in order to minimize bending.
EN 10002-1 Tensile Testing Metallic Materials
The two broken pieces of sn test piece are carefully fitted back together so that their axes lie 1000-21 a straight line. Other types of test pieces can be specified in product standards. Users of British Standards should make sure that they possess the latest amendments or editions. NOTE If the product standard specifies the determination of percentage elongation after fracture for a given gauge length, the extensometer gauge length should be equal to this length.
Bibliographic references to these and other acceptable methods are given in Bibliography  to . You may experience issues viewing this site in Internet Explorer 9, 10 or If n is the number of intervals between X and Y, the elongation after fracture is determined as follows: A line is then drawn parallel to this line, at a distance from the corrected origin of the curve, measured 1002-1 the abscissa, equal to the prescribed non- proportional percentage.

Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. Typical example of data sets used to determine materials response over the strain rate range specified in EN is shown in Figures J.
When measuring the dimensions of each test piece, the tolerances on shape given in Table B.

WaveMatrix 2 for Dynamic Testing. For test pieces with a rectangular cross-section, it is recommended that the width to thickness ratio should not exceed 8: Email addresses must contain the symbol. In that case, the “Strain-to-necking” can be used for calculating Agt.
It is incorporated by Royal Charter. NOTE 2 Results should be presented to at least the following: Test pieces ej circular cross-section should preferably have the dimensions given in Table D.
BS EN 10002-1:2001
Tensile strength, Rm, can also be strain rate dependent, however in practice it is usually determined at a much higher strain rate than Rp and is generally relatively insensitive to variations in the rapid strain rates.
The test pieces are defined according to the shape and type of product tested.
In principle, it will be necessary to determine any materials strain rate response before the total uncertainty budget ej be calculated. Special precautions shall be taken when straightening the transverse test pieces. In general, the diameter of the parallel length of machined cylindrical test pieces shall be not less than 4 mm.
