  • BS ISO 8637-3:2018 pdf free.Extracorporeal systems for blood purification Part 3: Plasmafilters. The performance characteristics specified in 4.3 shall be determined prior to marketing a new type of device and shall be re-evaluated after changes in the device that might alter its performance. The sample of device shall be drawn at random from the manufacturer’s production and shall have passed all applicable quality control steps, as well as sterilization. They shall be prepared according to the manufacturer’s recommendations as though they are to be used for a clinical procedure Measurements shall be made in vitro at (37 ± 1) °C. When the relationship between variables is nonlinear, sufficient determinations shall be made to permit interpolation between the data points. The techniques of measurement given in this document are reference tests. Other test methods may be used, provided they have been validated and shown to be precise and reproducible. The test systems shown do not indicate all the necessary details of practicable test apparatus. The design and construction of actual test systems and the establishment of actual test systems shall also address the many factors contributing to measurement error, including, but not limited to, pressure measurement errors due to static head…

  • ISO 16837-2019 pdf free.Non-destructive testing一Acoustic emission testing- Test method for damage qualification of reinforced concrete beams. 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…

If the verification is made outside this temperature range, this shall be stated in the verification report. 5.1.4 The instruments used for verification and calibration shall be traceable to national standards. 5.2 Calibration of the test force 5.2.1 Each test force used within the working range of the testing machine shall be measured. Whenever the indenter position affects the applied force, this shall be done at not less than three positions of the plunger uniformly spaced throughout its range of movement during testing. For testing machines whose test force is shown not to he influenced by the position of the plunger, e.g. closed-loop controlled loading system, the test force can be calibrated in one position. 5.2.2 The test force shall be measured by one of the…

Test pieces less than 50 mm thick shall be plied up. without the use of cement, to a minimum of 50 mm. For moulded products, the top skin shall be removed. Thicker test pieces can be used to avoid spurious results, which can occur with very soft materials due to the influence of the baseplate. NOTE The minimum test piece thickness of 50 mm cannot be sufficient for very soft materials: if spurious results are obtained, a thicker test piece can be used. Very low density materials can also cause problems due to rebound of the test piece itself. With multiple-ply test pieces, slipping can occur between the plies. This problem can be overcome by using the largest possible area of the test piece. 7 Number of test pieces Three test pieces per sample…
