BS EN 10002-1:2001
By agreement, the test piece may also consist of a strip with parallel sides. As-cast test pieces shall incorporate a transition radius between the gripped ends and the parallel length.
Email addresses must contain the symbol. 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. EN ISOetc. In order to render the fine scratches more easily visible, a suitable dye film may be applied to the test piece before testing.
It should be noted that when evaluating the total scatter in experimental results the uncertainty in measurement eh be considered in addition to the inherent scatter due to material inhomogeneity. Test pieces of circular cross-section should preferably have the dimensions given in Table D.
Complementary recommendations for computer controlled testing machines are indicated in the informative annex A to this standard. In that case, the bw can be used for calculating Agt. Ne n is the number of intervals between X and Y, the elongation after fracture is determined as follows: 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.
If the straight portion 100002-1 the force-extension diagram is not clearly defined, thereby preventing drawing the parallel line with bss precision, the following procedure is recommended see Figure 6. NOTE 1 For consideration of uncertainty, see annex J, which provides guidance for the determination 10002-1 uncertainty related to metrological parameters and values obtained from the interlaboratory tests on a group of steels and aluminium alloys.
The latter is obtained by dividing this force by the original cross-sectional area of the test piece So see Figure 3. Learn more about the cookies we use and how to change your settings. Calibration of force proving instruments used for the verification of uniaxial testing machines Part 4: If the parallel length Lc is much greater than the original gauge length, as, for instance, with unmachined test pieces, a series of overlapping gauge lengths may be marked.
NOTE 2 In case where the machine is operating in strain rate control, the stress rate should be calculated taking into account the modulus of elasticity of the material.
Information on standards BSI provides a wide range of information on national, European and international standards through dn Library and its Technical Help to Exporters Service. The original gauge length shall be not less than 20 mm. Take the smart route to manage medical device compliance.
The tolerances shown above for tensile testing represent maximum bound values, i. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. The test piece is usually obtained by machining a sb from the product or a pressed blank or bd.
The width of these ends shall be at least 20 mm and not more than 40 mm. Finally it should be appreciated that when suitable reference materials2 become available they will offer a useful means of measuring the total measurement uncertainty on gs given testing machine including the influence of grips, bending, etc, which at present have not been quantified.
Verification of extensometers hs in uniaxial testing Part 5: Subscribe to Our Newsletters. 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. If permission is granted, the terms may include royalty payments or a licensing agreement. The point where this line crosses the abscissa is the corrected origin of the force-extension curve see Figure 6.
The end point 100021 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.
In principle, this measurement is only valid if fracture occurs within the extensometer gauge length Le. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which 100021 be found on the inside front cover.

Prior to the test a sb small mark should be made near one of the ends of the fn length. The dimensions of this transition radius are important and it is recommended that they be defined in the product standard. Up-to-date lists dn bibliographical references concerning such national standards may be obtained on application to the Management Centre or to any CEN member. 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.
Parts 3 and 4 will be replaced by corresponding ISO standards. 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. Tables of standard tolerances grades and limits deviations for holes and shafts ISO Method of test at ambient temperature ” was approved by CEN on 27 November Various BSI electronic information services are also available which give details on all its products and services.
The longitudinal strip is generally used for tubes with a wall thickness of more than 0,5 mm. These recommendations are related to the design, the software of the machine and its validation and to the operating conditions of the tensile test.
In particular it provides the recommendations which should be taken into account in the software and testing conditions. The original cross-sectional area of the length of tube or longitudinal or transverse strip may be determined from the mass of the test piece, the length of which has been measured, and from its density.
