ISO 3452-3-2013 pdf free.Non-destructive testing – Penetrant testing一 Part 3: Reference test blocks. ISO 3452-3 describes two types of reference blocks: Type I reference blocks are used to determine the sensitivity levels of both fluorescent and colour contrast penetrant product families: — Type 2 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetran( testing. The reference blocks are to be used in accordance with part I of this International Standard. 2 Normative references The following referenced documents, in whole or in part. are normatively referenced in this document and are indispensable for its application.

ISO 9934-1-2016 pdf free.Non-destructive testing一Magnetic particle testing Part 1: General principles. 9.1 Properties and selection of media The characterization of detection media shall he in accordance with ISO 9934-2. Various types of detection media exist in magnetic particle testing. Usually the detection media is a suspension of coloured (including black) or fluorescent magnetic particles in a carrier fluid. Water- based carriers shall contain wetting agents and usually a corrosion inhibitor. Dry powders are also available. They are generally less able to reveal fine surface discontinuities. Fluorescent detection media usually gives the highest sensitivity provided there is an appropriate surface finish. good drainage to maximize indication contrast, and well controlled viewing conditions, in accordance with Clause 10. Coloured detection media can also offer high sensitivity if the contrast with the part surface is sufficient. Black and other colours are available. NOTE To achieve good colour contrast between discontinuities and the test surface, it might be necessary to apply a thin layer of contrast aid paint in accordance with (‘lauj and 10. 9.2 Testing of detection media ISO 9934-2 defines mandatory and recommended tests that are to be carried out before or periodically during inspection. A sensitivity check shall be carried out…

BS ISO 18211:2016 pdf free.Non-destructive testing – Long-range inspection of above-ground pipelines and plant piping using guided wave testing with axial propagation. This International Standard specifies a method for long-range testing of carbon and low-alloy steel above-ground pipelines and plant piping using guided ultrasonic waves with axial propagation applied on the entire circumferential pipe section. in order to detect corrosion or erosion damage. The guided wave testing (GWT) method allows for fast inspection of above-ground pipelines, plant piping and cased road crossings, giving a qualitative screening and localization of probable corroded and eroded areas. GWT is typically performed on operating piping systems. This International Standard is applicable to the following types of pipes: a) above-ground painted pipelines; b) above-ground insulated pipelines; c) painted plant piping; d) insulated plant piping. NOTE Pipe sections within road crossings with external casings (without bitumen or plastic coating) are a special case of burled pipe where there is no soil pressure on the OD of the pipe. This International Standard applies to these cased road crossings. Other types of pipes not included in the above list need dedicated approaches due to increased complexity. 2 Normative references The following documents, in whole or in part, are…

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…

ISO 18081:2016 pdf free download.Non-destructive testing Acoustic emission testing (AT) Leak detection by means of acoustic emission Essais non destructifs — Con trôle par emission acoustique — Detection defuites par emission acoustique. 5.3 Influence of pressure differences The pressure difference is the primary factor affecting leak rate. However, the presence of leak paths may depend on a threshold value of fluid temperature or pressure. Pressure dependent leaks and temperature dependent leaks have been observed, but in extremely limited number. Pressure- dependent or temperature-dependent leaks denote a condition where no leakage exists until threshold pressure or temperature is reached. At this point, the leakage appears suddenly and may be detectable. When the pressure or temperature is reversed, the leakage follows the prescribed course to the critical point at which leakage drops to zero. Temperature and pressure are not normally applied in the course of leak testing for the purpose of locating such leaks. Instead, they are used to force existing discontinuities to open, so as to start or increase the leakage rate to point of detection. An example of this effect is the reversible leakages at seals below the service temperature and/or service pressure. AE waves emitted by a leak will…
