Adjust concentration to required value. Testing of penetrant materials. Since once again the material will only be used for one inspection thesetests are not applicable. In case of penetrant material packed in spray cans, the content of sulfur and halogens shall be additionallydetermined according to 7.

BS EN ISO 3452-2:2013

In order to maintain the integrity of a penetrant process, the 34522- as a whole and the individual components ofthe system shall be regularly checked to ensure that they meet the required standards. These papers shall be kept dry in a dessiccator until use. The test shall be carried out by an independent laboratory.

The fluorescent brightness of each specimen is determined as per themethod in A. ENMetallic products – Types of inspection documents. As an alternative, the method described in 7. Allow the equipment to stabilise prior to use. 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. Zerst rungsfreie Pr fung – Eindringpr fung – Teil 2: Pr fungEssais des produits de ressuage ISO The best way is to counteract adsorption effect on the entrapped penetrant due to the discontinuity walls by astronger capillary effect.


Liquid penetrant inspection of seamless and welded steel tubes for the detection of surface imperfections. Corrosive properties except formType and batch7.

Enn solvent-based non-aqueous wet developer is the right means. Indications from pealable developers are not the same as obtainedusing standard developers. The source of UV-A radiation is positioned inclose proximity to the test panels.

Penetrant Testing (РТ)

It is often advantageousto also use a component with known discontinuities typical of those normally expected.

Click to learn more. All parts of the test shall be carried out at ambient temperature. Testing of penetrant materials ISO These test panels shall be reserved for the use with type I penetrants only. The result shall berecorded at the temperature used for the type test. A visibility measuring equipment consists for example of the following elements see Annex D: Penetrant testing at temperatures lower than 10 degrees C ISO Classification can be carried out as for colourcontrast systems.

This information isgiven for the convenience of users of this standard and does not constitute an endorsement by CEN ofthe product named. The following information shall be included: Atleast every 24 months the unit shall be calibrated. The tests may becarried out at more frequent intervals or additional tests carried out if necessary to ensure correct processingconditions.

Containers and their contents shall be compatible. Additionally, most traditional methods, based sensitivitylevels directly or indirectly on the quantity of fluorescent material dn the penetrant, i.

Measure the density of the sample using a hydrometer. In the case of products conditioned in a spray can, purge the latter for 5 s before sampling and, at the moment ofweighing, spray the content of the can into a ml beaker, then pour immediately the product into the platinumboat. The procedure employed in 7.

This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by Octoberand conflicting national standards shall be withdrawn at the latest byOctober For undated reference the latest edition of the publication referredto applies.

Any of thesesuggests that the treatment system is not functioning effectively. Record the level to which the fluorescent intensities are similar. Testing ofpenetrant materials 342-2 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, bss so, how reproducible it is.

Penetrant testing at temperatures higher than 50 degrees C ISO However, the Viennaagreement was applied during the work, so some European Standards have referenced them under their previousEuropean number. Allnecessary precautions shall be observed.

The vs detailed in 7. EN ISO comprises a series of European standards of penetrant testing which is made of the following: Total halogen content chloride and fluoridewithout evaporation, shall be less than The following procedure shall be used: Check the level of the tank and bring it back to its original level by the addition of water and mix thoroughly.
