The end point can be determined by constructing two lines, the first being horizontal from the last point of zero slope and the second as a tangent to the strain hardening section of the curve as close as possible to the point of inflection. Worldwide Standards We can source any standard from anywhere in the world. Contact the Information Centre.

BS EN 10002-1:2001

Some limited data and the following examples may be used to estimate uncertainty for some classes of materials. If n is the number of intervals between X and Y, the elongation after fracture is determined as follows: After fracture, the broken test piece should be placed in a fixture and axial compressive force applied, preferably by means of a screw, sufficient to firmly hold the pieces together during measurement.

EN was composed of five parts: Typical results from various intercomparison exercises are given in J. In any case, it should be recommended that pertinent limits for the range can be selected by the user in order to eliminate senseless values of the slope of the curve in the elastic range. In case of dispute, the extensometer method shall be used. September Replaced By: In principle, it will be necessary to determine any materials strain rate response before the total uncertainty budget can be calculated.

Austenitic steels ISO Standards are also available from the BSI website at http: Other types of test pieces can be specified in product standards. Verification of extensometers used in uniaxial testing Part 5: Bss response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

In general, the diameter of the parallel length 10002-1 machined cylindrical test pieces shall be not less than 4 mm. How can we help you? Tables of standard tolerances grades and limits deviations for holes and shafts ISO A version in any other language made by translation under 10002- responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official versions.

A list of organizations represented on this subcommittee can be enn on request to its secretary. The dimensions of this transition radius are important and it is recommended that they be defined in the product standard. However since there is insufficient quantitative data available it is not possible to include their effects in uncertainty budgets at present. Ensure use of the most current version of this document by searching British Standards Online at bsonline.

Verification of the force measuring system of the tensile testing machines Part 3: These various documents all give guidance of how to estimate uncertainty of measurement based upon an “uncertainty budget” concept. When hs extensometer is used it shall be at least of class 1 according to EN for the determination proof strength non-proportional extension ; for other properties with higher extension a class 2 extensometer according to EN can be used.

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 een minimize bending. When this procedure is used, it should be recorded in the test report.

The measurement of the final gauge length after fracture L’u is made on the longest broken part of the test piece and should be accurate to within 0,5 mm. 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 [7].

This length which is function of the value of the percentage total elongation fn be defined in the product standard. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. NOTE 1 This procedure confirms only that the machine finds the material characteristics for the particular test piece form, material tested and conditions used. If this rate cannot be regulated directly, it ns be fixed by regulating the stress rate just before yield begins, the controls of the machine not being further adjusted until completion of yield.

Any areas which have been hardened by shearing or pressing shall be removed by machining. Special precautions shall be taken to ensure proper contact between the broken parts of the test piece when measuring the final gauge length. In particular it provides the recommendations which should be taken into account in the software and testing conditions.

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. Learn more about the cookies we use and how to change your settings.

One of the recommended methods is as follows: The force is then increased again until it exceeds the value obtained originally. In cases of dispute, the value, D, shall be used, as long as there is sufficient material.

A correction of the extension should only be carried out to take into account the 01002-1 of the preliminary force.
