There are two types of non-proportional test pieces, with dimensions as fn in Table B. The parallel length Lc shall always be greater than the original gauge length Lo.

The method used should be verifiable. This measurement is, in principle, valid only if the distance between the fracture and the nearest gauge mark is not less than one third of the original gauge length Lo. In case of dispute, the extensometer method shall be used. For undated references the latest edition of the publication referred to applies including amendments. Search all products by. It 100021- the intention, based on further developments by manufacturers and rn that annex A will become normative in the next revision of this standard.
For detailed descriptions, see  and . The test involves straining a test piece in tension, generally to fracture, for the purpose of determining one or more mechanical properties. The two broken pieces of the test piece are carefully fitted back together so that their axes lie in a straight line.
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.
For test pieces with a rectangular cross-section, it is recommended that the width to thickness ratio should not exceed 8: It supersedes BS EN Ensure use of the most current version of this document by searching British Standards Online at bsonline.
BS EN Tensile testing of metallic materials. Email addresses can only contain letters, numbers and the following special characters: The longitudinal strip is generally used for tubes with a wall thickness of more than 0,5 mm.

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. It should be noted that the expanded uncertainties have been calculated using a simplified approach based on the GUM.
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. Every endeavour should be made to ensure that test pieces are held in such a way that the tension is applied as axially as possible, in order to minimize bending. Because of the shape of the stress-strain curve, some of the tensile properties in principle can be determined with a higher degree of precision than others, e.
A type B evaluation is based on some other means ; Thus the use of tolerances specified in a standard comes under the type B category. Calibration of force proving instruments used for the verification of uniaxial testing machines 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. Users of British Standards should make sure that they possess the latest amendments or editions.
The dimensions of this transition radius may be important and it is recommended that they be defined in the material specification if they are not given in the appropriate annex see 6.
NOTE 1 For consideration of uncertainty, see annex J, which provides guidance for the determination of uncertainty related to metrological parameters and values obtained from the interlaboratory tests on a group of steels and aluminium alloys. The marking of the initial gauge length L’o should be accurate to within 0,5 mm. In principle, this measurement is only valid if fracture occurs within the extensometer gauge length Le.
In order 10002-11 the measurement is valid, the two following conditions should be respected: In practice the requirements and tolerances of the present standard do not allow all the effects to be quantified. Software for Series Systems. In particular, 10002- distinction is made between: Its complexity has provided the driving force for a number of organisations to produce simplified versions of the GUM, , , .
This annex has now been revised to more closely follow the approach for estimating the uncertainty of measurement outlined in the guide established by ISO TAG4 . EN ISOetc.
