If the straight portion of the force-extension diagram is not clearly defined, thereby preventing drawing the parallel line with sufficient precision, the following procedure is recommended see Figure 6. Special precautions shall be taken when straightening the transverse test pieces. NOTE This clause only applies to materials having yield phenomena and when Ae is not ej to be determined.

The force is then increased again until it exceeds the value obtained originally. By continuing to use our site, you accept our cookie policy. Copyright Copyright subsists in all BSI publications.

Typical results from various intercomparison exercises are given in J. Using a pair of needle-pointed dividers set at the gauge length, an arc is scribed with the mark as a centre.

The Expression of Uncertainty and Confidence in Measurement. Bluehill LE for Basic Testing. The minimum transition radius between the grips ends and the parallel length shall be: EN ISOetc.

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.

NOTE 2 Results should be presented to at least the following: 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 100002-1 of tensile results measured by different laboratories using similar material.

NOTE 1 A three-degree polynomial regression is recommended. Confidence may be placed in the efficiency of the machine computer processing, if differences between computer determined values and those determined by analogue means on the same test piece gs small. Summary of pages This document comprises a front cover, an inside front cover, the EN title page, pages 2 to 56, an inside back cover and a back cover.

Procedure for diffusion flame. In the case of non-proportional test pieces, the original gauge length Lo is taken independently vs the original cross-sectional area So.

Prior to the test a very small mark should be made near one of the ends of the parallel length. NOTE For the determination of upper and lower yield strengths, the use of an extensometer is not necessary.

A British Standard does not purport to include all the necessary provisions of a contract. In cases of dispute, the value, D, shall be used, as long as there is sufficient material.

Verification of the force measuring system of the tensile testing machines Part 3: In order to render the fine scratches more easily visible, a suitable dye film may be applied to the test piece before testing. It is incorporated by Royal Charter. When this procedure is used, it should be recorded in the b report. The uncertainty budget presented here could be regarded as an upper bound to the measurement uncertainty for a laboratory undertaking testing in compliance with EN since it is possible that a laboratory could actually control some of the testing parameters to bd better level eh precision than that demanded by the standard, e.

Find Similar Items This product falls into the following categories. Specimens are gripped ensuring that the specimen is aligned axially to minimize bending.

The method used should be verifiable. In the case of reduction in area, Z, the measurement tolerance for cross-sectional area both before and after fracture needs to be considered.

Typical example of data sets used to determine materials response over the strain rate range specified in EN is shown in Figures J. Email addresses e contain the symbol. NOTE Comparisons of percentage elongation are possible only when the gauge length or extensometer gauge length, the shape and area of the cross-section are the same or when the coefficient of proportionality k is the same.
