Parts may be stored in a protective envelop to prevent scratching, twisting, anymechanical or thermal shock. Additionally, most traditional methods, based sensitivitylevels directly or indirectly on the quantity of fluorescent material in the penetrant, i.
Penetrant Testing (РТ)
It is the responsibility of the supplier to choose which parameters are to be checked. The following table gives the correspondance between these different numbers.
One shall be the nominal concentration, two shall be above and two below thenominal concentration. Penetrant testing at temperatures higher than 50 degrees C ISO Illumination levelson the test panel should not bss altered during the test. The photomultiplier tube and chart recorder specifications is such that when illuminated in accordance with D.
Zerst rungsfreie Pr fung – Hs fung – Teil 2: Test panels shall be reserved for the use with typeII penetrants only.

Check the level of the tank and, if necessary, add water to bring it back to its original level and mix thoroughlyto ensure a full and uniform suspension. The test panel shall then be inspected. Resonant inspection Stress measurement Thermography Ultrasonic methods Ultrasonic advanced methods Ultrasonic flaw detection Ultrasonic thickness gauging Visual inspection Other methods.
If it is necessary to change sensitivity ranges on a chart recorder between setting up with the standard sample andrunning the test panel, zero and full scale deflection settings shall remain unaltered. Since once again the material will only be used for one inspection thesetests are not applicable.
Both have similar average brightness of indications and, so would be labelled as equivalentsensitivity by some test methods. PropertyTestTest methodaccording rn clauseAppearanceBatch7. We maintain physical, electronic ba procedural safeguards in connection with the collection, storage and disclosure of personally identifiable customer information. In reality, whilst fluorescent brightness is onemajor factor in penetrant sensitivity, tests have shown that the probability of detection of a discontinuity is alsodependent upon whether a penetrant stays in a discontinuity and, if so, how reproducible it is.
Be sure to sign off when you finish using a shared computer. Classification can be carried out as for colourcontrast systems.
A ba measuring equipment consists for example of the following elements see Annex D: At leastevery 24 months the unit shall be calibrated.
Containers and their contents shall be compatible. The tests may becarried out at more frequent intervals or additional tests carried out if necessary to ensure correct processingconditions. You may experience issues viewing this site in Internet Explorer 9, 10 or The result of this test 352-2 be reported. Adjust concentration to required value. This specification sets out to address these issues by using hs method for determining sensitivity that: As an alternative, the method described in 7.
The blanking plate has an aperture to ensure that the photomultiplier receives the emitted light from only onediscontinuity on the test panel, at the same 34552-2. Take a sample of the contents of the tank and adjust the temperature to 20 C or to the temperature at whichthe hydrometer has been calibrated.
The faster, easier way to work with standards. This information is given for the convenience of usersof this standard and does not constitute an endorsement 352-2 CEN of the product named. The panels shall be left for a period of 24 hours at roomtemperature after which time they shall be cleaned and inspected as per 7. This European Standard is considered to be a supporting standard to thoseapplication and 33452-2 standards which in themselves support an essential safety requirement of a New ApproachDirective and which make reference to this European Standard.
Before using the luxmeter the operator shall check the stickers for the “valid to” or “calibrate before” dates. The test refractometer rn be calibrated using accurately prepared solutions of the new hydrophilic emulsifier.

Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Product performance, see 7. These reference samples shall hs stored in light-proof sealed containers. Otherwise, the penetrant shall be discarded and replaced. Indications from pealable developers are not the same as obtainedusing standard developers.
Any of thesesuggests that the treatment system is not functioning effectively. To estimate the concentration of the hydrophilic remover, read the value given by a sample of the freshly preparedproduct and determine its concentration from the graph.
