BS EN ISO 6892-2:2018 pdf free.Metallic materials – Tensile testing Part 2: Method of test at elevated temperature. The force-measuring system shall be set to zero after the testing equipment has been assembled but before the test piece is actually placed in the gripping jaws. Once the force zero point has been set, the force-measuring system may not be changed in any way during the test. NOTE The use of this method ensures that the weight of the gripping system is compensated in the force measurement and that any force resulting from the clamping operation does not affect the force zero point. 10.2 Gripping of the test piece, fixing of the extensometer and heating of the test piece, not necessarily in the following sequence 10.2.1 Method of gripping For requirements concerning the method of gripping, see ISO 6892-i. NOTE Maintaining a very small tensile load (e.g. test machine in load control) during heating period and soaking time can prevent possible compressive stresses due to thermal expansion. 10.2.2 Fixing of the extensometer and establishing the gauge length 10.2.2.1 General Different methods of establishing the extensometer gauge length are used in practice. This can lead to minor differences in the test results….

BS ISO 15461:2018 pdf free.Steel forgings一Testing frequency, sampling conditions and test methods for mechanical tests. 5.1 For the testing frequency of room temperature tensile tests and of impact tests, the requirements given in JJ1 to apply. 5.1.1 The product standard or order shall specify, by reference to the appropriate symbol(s) in Table 1. column 1, the following: a) the composition of the test unit as defined in Table 1. columns 2 to 8; b) whether uniformity checks by hardness tests in accordance with Table 1. column 9 are required and, if so, the percentage of products to be subjected to the hardness tests; c) the number of sample products to be taken from the test unit. (See the explanations in Table 1. footnote a, for replacing the letter “n of the symbol by the mass of the test unit up to which the taking of one sample product is sufficient.) NOTE Less stringent requirements for the composition of the test unit can be compensated by more stringent requirements for the number of sample products to be tested. Therefore, for example, a test unit characterized by the symbol CH5 can be regarded as equivalent to a test unit characterized by the…

BS ISO 13605:2018 pdf free.Solid mineral fuels – Major and minor elements in coal ash and coke ash – Wavelength dispersive x-ray fluorescence spectrometric method. Discs may be prepared by the casting or press-quenching technique. Both methods will produce glass discs of adequate quality. If the casting technique is used, the sample may be fused with the flux in a crucible and then poured into a separate mould; if an appropriately shaped crucible is used, the fusion may be carried out and the glass allowed to cool in the same crucible. A conventional electric furnace, high-frequency furnace, or gas burner may be used for heating. Disc-making machines are available commercially, and these may be used to fuse and cast the discs. Prior to measurement, discs shall be inspected visually, paying particular attention to the analytical surface. The discs shall not contain undissolved material, and shall be whole and free from crystallization and bubbles. Defective discs shall be re-fused or discarded and substitute discs prepared. Laboratory-prepared ashes for XRF analysis should be freshly prepared; if not, It will be necessary to reheat these to the ashing temperature and hold for 15 mm at this temperature prior to preparation of the XRF…

BS ISO 10804:2018 pdf free.Restrained joint systems for ductile iron pipelines – Design rules and type testing. 4.1 All restrained joints for ductile iron pipes, fittings and other components shall be designed in accordance with this clause. If the design of a restrained joint has been tested and successfully used for a minimum of 10 years, a type test as described in Clause 5 is only required for a significant change in the design which could adversely affect the performance of the restrained joint. 4.2 The minimum thickness of the spigot for restrained joints shall allow any necessary welding or loading from attachments (e.g. gasket teeth). This may result in a pipe thicker than the corresponding pressure class thickness of the pipe. The manufacturer shall declare the pipe thickness for their restrained joints. 4.3 The design safety factors with respect to failure against axial forces due to internal pressure shall be such that the joints shall withstand a type test of 1,5 times the allowable operating pressure (PFA) pIus 5 bar (5 x 105 Pa).1) 4.4 The joints shall be type tested to a negative pressure of 0,9 bar (9 x 104 Pa) below atmospheric pressure [approximately 0,1 bar (104…

The internal noise of the amplifier shall be inherently low and less than 20 1.tV (26 dBAE for 0 dBAE = 1 iV) as the peak voltage converted by input voltage. The amplifier shall be also robust enough against the environmental conditions and be protected properly. The frequency range shall be determined prior to the measurement, taking into account the performance of AE sensor and the amplifiers. A suggested range in concrete is from around 10 kFIz to 100 kHz, because such higher frequency components as over 1 MHz readily attenuate in concrete. For signal analysis, AE parameters of AE count or AE hit shall be detected and processed. The measurement system shall be able to obtain time information along with AE data. In addition, such external parameters as load, strain and so forth are preferably recorded in the system, which can be equipped with enough memory to record the data measured. It is preferable that all the data recorded be analyzed digitally by computer. 5 Environmental noises In advance of the AE measurement, the noise level shall be estimated. Then, counteract against external…
