BSI offers members an individual updating service called PLUS which ensures that subscribers automatically receive the latest editions of standards.

In any case, it should be recommended that pertinent limits for the ej can be selected by the user in order to eliminate senseless values of the slope of the curve in the elastic bbs. The longitudinal strip is generally used for tubes with a wall thickness of more than 0,5 mm. EN ISOetc. Click to learn more. To fully comply with the assessment of uncertainty it would be necessary to consider all the possible sources of uncertainty contributing to the measurements including those due to uncertainties in the devices used in the calibration chain, i.

NOTE For the determination of upper and lower yield strengths, the use of an extensometer is not necessary. In principle, this measurement is only valid if fracture occurs within the extensometer gauge length Le. In principle, it will be necessary to determine any materials strain rate response before the total uncertainty budget can be calculated.

Since the equivalent tolerances, a, are based on measured data, using a simple least mean squares fit to the data, it is necessary to decide what distribution model of the uncertainties is appropriate in accordance with the GUM. Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.

Therefore for stainless steel, the combined standard uncertainty of Rp0,2 is given by: In no case, the stress rate in the elastic range shall exceed the maximum rates given in Table 3.

The point at which this line intersects the curve gives the force corresponding to the desired proof strength non-proportional extension. Figure 11 – Proportional test pieces see annex D Li ce ns ed C op y: Data which are derived directly from the machine transducers or amplifiers should be collected and processed using equipment with frequency band width, sampling frequency and uncertainty at least equal to those used to provide the machine computer calculated results. The test piece is usually obtained by machining a sample from the product or a pressed blank or casting.

The width of these ends shall be at least 20 mm and not more than 40 mm. Details and advice can be obtained from the Copyright Manager. Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. The dimensional tolerances of the test pieces shall be in accordance with the appropriate annexes see 6.

We use cookies to improve your browsing experience. NOTE 1 This procedure confirms only that the machine finds the material characteristics for the particular test piece form, material tested and conditions used.

As-cast test pieces shall incorporate a transition radius between the gripped ends and the parallel length. By agreement, the test piece may also consist of a strip with parallel sides. If the straight portion bbs 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. It is a comprehensive document of over 90 pages based upon rigorous statistical methods for the summation of uncertainties from various sources.

Concrete, Asphalt and Rock.

The force is then increased again until it exceeds the value obtained originally. It 10020-1 be noted that 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.

NOTE In cases where the percentage elongation after fracture is not to be determined, a distance between the grips of at least 50 mm may be used. Overview Product Details This European Standard, a part of the BS EN series, specifies the method for tensile testing of metallic materials and defines the mechanical properties which can be determined at ambient temperature.

The nominal width of the test piece may be used, provided that the machining tolerances and tolerances on shape given in Table B.

For products of width equal to or less than 20 mm, the width of the test piece may be the same as that of the product.

It is incorporated by Royal Charter. However since there is insufficient quantitative data available it is not possible to include their effects in uncertainty budgets at present.
