The gripped ends may be of any shape to suit the grips of the testing machine. They should be given in basic Sl units relating to the force, the extension, the time and the test piece dimensions.
BS EN 10002-1:2001
The intersection between these two lines represents the end of yield point extension. However since there is insufficient quantitative data available it is not possible to include their effects in uncertainty budgets at present.
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. Transverse or longitudinal test piece dimensions other than those given bss annexes B and D can be specified in the product standard.
The measurement is valid regardless of the position of the fracture cross-section if the percentage elongation after fracture is equal to or greater than the specified value.
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. The tolerances shown above for tensile testing represent maximum bound values, i.
Types A and B. The point at which this line intersects the curve gives the force corresponding to the desired proof strength non-proportional extension.
Compliance with a British Standard does not of itself confer immunity from legal obligations. In any case, it should be recommended that pertinent limits for the range can be selected 10020-1 the user in order to eliminate senseless values of the slope of the curve in the elastic range.
The method consists of measuring on the longer part of a broken test piece which has been submitted to a tensile test, the percentage non-proportional elongation at maximum force, from which the percentage total elongation at maximum force is calculated. In order that the measurement is valid, the two following conditions should be respected: Specimens are gripped ensuring that the specimen is aligned axially to minimize bending.
Ensure use of bd most current version of this document by rn British Standards Online at bsonline.
The test pieces are defined according to the shape and type of product tested. We recommend that you read and review the standard in full to ensure suitability for the products you wish to test before selecting test equipment.
NOTE If the straight portion of the force extension diagram is not clearly defined, refer to The 1002-1 based on 10002- calculation of the characteristics of a sliding segment are the most convenient.
They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator.

It should be noted 100022-1 it is not possible to give an absolute statement of uncertainty for this test method because there are both material dependent and material independent contributions to the uncertainty statement.
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. The beginning is at that point where the slope becomes zero and is represented by a horizontal line. In the case of test pieces where the width is the same as that of ba product, the original cross-sectional area So shall be calculated on the basis of the measured dimensions of the test piece.
Using a pair of needle-pointed dividers set at the gauge length, an arc is scribed with the mark as a centre.

The method used should be verifiable. Subscribe to Instron News! Other types of test pieces can be specified in product standards. The marking of the initial gauge length L’o should be accurate to within 0,5 mm. 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. The slope of the curve in the elastic range corresponds to the mean slope in a range where the following conditions are fulfilled: Amendments issued since publication Amd.
