A list of organizations represented on this subcommittee can be obtained on request to its secretary. The beginning is at that point where the slope becomes zero and is represented by a horizontal line. This length which is function of the value of the percentage total elongation should be defined in the product standard. Data which are derived directly from the machine transducers or amplifiers should be collected and processed e equipment with frequency band width, sampling frequency and uncertainty at least equal to those used to provide the machine computer calculated results.
For this purpose, the two broken pieces of the test piece are carefully fitted back together so that their axes lie in a straight line.
Bluehill LE for Basic Testing. Any areas which have been hardened by shearing or pressing shall be removed by machining. NOTE 1002-1 annex A indicates complementary recommendations for computer controlled testing machines. The width of these ends shall be at least 20 mm and not more than 40 mm.
10020-1 various documents all give guidance of how to estimate uncertainty of measurement based upon an “uncertainty budget” concept. To determine the desired proof strength a line is drawn through the hysteresis loop. When measuring the dimensions of each test piece, the tolerances on shape given in Table B. 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 .
The precision of the test results from a tensile test is dependent upon factors related to the material being tested, the test piece geometry and machining, the testing machine, the test procedure and the methods used to calculate the specified material properties.

EN Tensile Testing Metallic Materials – Instron
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 b to a better level of precision than that demanded by the standard, e.
Take the smart route to manage medical device compliance. The measurement of the final gauge length after bd L’u is made on the longest 100022-1 part of the test piece and should be accurate to within 0,5 mm. Subscribe to Our Newsletters. A correction of the extension should only be carried out to take into account the effect of the preliminary force.
Next Checking to see if you are a returning visitor…. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. However since there is insufficient quantitative data available it is not possible to include their effects in uncertainty budgets at present.
BS EN 10002-1:2001
The Expression of Uncertainty and Confidence in Measurement. Special precautions shall be taken to ensure proper contact between the broken parts of the test piece when measuring the final gauge length. The intersection between these two lines represents the end of yield point extension. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.
In practice, such sources of error are second order effects and for the purposes of this document a simplified approach will be adopted using the concepts outlined in the GUM. In the case of non-proportional test pieces, the original gauge length Lo is taken independently of the original cross-sectional area So.
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 110002-1 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. For undated references the latest edition of the publication referred to applies including amendments.

Figure 12 – Test pieces comprising a length of tube see annex E Li ce ns ed C op y: 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. This is of particular importance when testing brittle materials or when determining proof strength non-proportional extension or proof strength total extension or yield strength.
They should be given in basic Sl units relating to the force, the extension, the time and the test piece dimensions. In particular it provides 01002-1 recommendations which should be taken into account in the software and testing conditions. 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.
It should 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.
