Penetrant testing (PT), how it works
3
The penetrant method of non-destructive testing is based on capillary penetration of indicator liquid (penetrant) into the surface defects (cracks, pores etc.). After intermediate cleaning and subsequent drying, a developer is applied as a thin, white layer onto the surface to be inspected. The developer “pulls” the penetrant out of the surface defects and makes them visible as coloured, linear or rounded indications. Documentation is possible by means of adhersive foil, photographic or video techniques. Penetrant testing systems Met-L-Chek, Standard Chek, Nord-Test are reliable in detecting the defects with a width down to the range of µm. Necessary condition: defects must be open to surface. Systems are also used for the leak testing.
The examination of testing media adequacy is done in accordance with : • AMS 2644 • AMS 2647 • DIN EN ISO 3452-2 (3) • ASME
Penetrant inspection can accurately and easily detect surface defects independent of types, materials and surface configurations of the objects to be tested. Other methods of non destructive testing, can only be applied for these requirements with restrictions.

Areas of use: Aircrafts industry, Metallurgy, nuclear industry, Electrical engineering, Engineering, Foundry, Blanking, Shipbuilding, Medicine, Car production. Work with materials: Alloyed and plain steel, cast iron, platings, plastics*, welds, nonferrous metals, products of powder metallurgy, steatite, ceramics*, other synthetic materials. *check for adequacy MET-L-Chek, Standard- Chek & Nord-Test* Used in temperature ranges from -5°С to + 50°С. In low temperatures (from -5 °С to + 10 °С ) it is necessary to increase time of penetrating. One must take into account peculiar specifications according to DIN EN ISO 3452 part 2 & EN 571 part 1.

Test body JIS Z 2343 Used to determine the sensitivity of penetrant systems and for comparing two penetrants, one of which can be taken for standard. Consists of two test panels which are bronze planes 100х35х2 mm , covered with NiCr-layer. In NiCr-blanket. Crosscut cracks are made, depth of which fits the width of the NiCr-blanket. (Designed in 4 types 10, 20, 30 & 50 µm). The quotient of cracks’ width to their depth equals 1:20. Each test-panel has a certificate according to EN 10204, type 3.1 B, which verifies its aptitude to EN ISO 3452-3. Test-panels with cracks width of 10 µm, 20 µm, 30 µm used for a fluorescent sensitivity testing penetrant systems. The sensitivity of contrast penetrant systems is determined by means of panels, depth of cracks in which - 30 and 50 µm.
Reference block №1 (EN ISO 3452-3) The type 1 reference block consists of a set of 4 nickel-chrome plated panels with 10, 20, 30 and 50 µm thickness of plating respectively. The 10, 20 and 30 µm panels are used for determination of the sensitivity of fluorescent penetrant systems. The sensitivity of colour contrast penetrant systems is determined by using the 30 and 50 µm panels. The type 1 panels are rectangular in shape with typical dimensions of 35 x 100 x 2 mm Transverse cracks are made in each panel by stretching the panels in the longitudinal direction. The width to depth ratio of each crack should be approximately 1:20. A declaration stating conformance to EN ISO 3452-3 and in line with EN 10204, Type 3.1 B shall accompany each test block.
Article No. 127.400.001
Test body №2 (EN ISO 3452-3) The reference block 2 consists of an austenitic base plate, which is chromiumplated on one side and provided with 4 different surface roughnesses on the other side. 5 star-shaped crack patterns of different sizes are generated in the chromiumplated side by applying a pressure load to the rear side with a ball. The rough areas are used for control of the intermediate rinse step. The indication on the reference block gives no suggestion of the indication on the part under test. The user uses the reference block for the control of inspection material. For checking the rinsability of penetrants four adjacent areas sized 25 x 35 mm are placed on one half of the panel with roughness of Ra = 2,5 µm, Ra = 5 µm, Ra = 10 µm and Ra = 15 µm. The defect area is located on the other half of the test surface of the panel. The size of each defect is determined optically at its maximum diameter using calibrated scales
Article No. 127.550.000
Test panel ASME V Used for the testing of the penetrants indication sensitivity. Due to the division of the test panel into two parts, it is possible to compare 2 different penetrants. Present test panel is an aluminium plate (80х50х10 mm), divided by a notch (50х2х1,5 mm), into two parts. Because of a special thermal treatment ASME panel, there is a uniform crack pattern, which is visible on both sides of the test panel.

Test panel WTP-1 & WTP-2 Designed to evaluate removability of the fluorescent penetrant. Panel WTP-2 is a stainless steel panel, measuring 4×6 inches and 0,090” thick with two parallel “medium rough” strips, each 6×1,5” inches, separated by a smooth 1 inch strip. The panel is used to evaluate the quality of removability according to the requirements of MIL-STD-6866 & ASTM E1417.

Test panel PSM-5 Present test panel is used for testing the penetrant process in whole. Test-panel PSM-5 is rectangular,10х15cm, width 2,3mm, made from stainless steel. The chromium-plated strip on the side contains 5 crack patterns. The raised, circular or star-shaped crack patterns are arranged according to their sizes. The biggest defect becomes visual after low-sensitive penetrant`s treatment. The smallest defect can hardly be seen even after application of highly sensitive penetrants. There are no two identical panels. The crack pattern differs from one panel to another. Test panel is designed in two models. Both models are designed in accordance with specification PrattWhitney P/N TAM 146040. The panel is not to be used for detecting the sensitivity of penetrant’s system.

Magnetic particle testing The magnetic particle testing method (MT) is one of the most sensitive, reliable and productive NDT-method for surface inspection of products from ferro-magnetic materials. The method is based on the attraction of ferromagnetic particles by force of leakage flux like cracks, laps, leak of fusion, pores which appear above surface defects after adequate magnetization. MT can be used for surface defects (open to the surface) and under certain conditions for detection of near-surface defects. Higher probability of detection is given, when the direction of a defect is perpendicular to the direction of the applied magnetic field. The smaller the angle between defect and field direction the weaker the indication

Magnetic Particle testing is used in almost every industry branch: metallurgy, machine building, aircraft building, shipbuilding, during production in steelworks, at pipe installation), electric power and chemical machine building, Means of transportation (aircrafts, rail cars, vehicles). Magnetic Particle testing procedure consists of the following: 1 Preparation of the items` surfaces of the test objects for testing, 2 magnetization of the object, 3 application of magnetic particle suspension onto the test object 4 Testing of the object, 5 demagnetization. Circular, longitudinal and combined magnetization are used for MT. There are a lot of magnetization schemes, some of which are shown below.

One Stepp towards safety – chain testing according DIN and UVV* * german regulations for the prevention of industrial accidents
You are already testing according to DIN 685 §5 or UVV 18.4 ? Carrying chains, especially chain slings have to be flaw-tested after at least 3 years of operation according to DIN standard 685, chapter5, pragraph 4.3.1 chapter 26, paragraph 3 of regulation no. 18.4 for the prevention of industrial accidents also requires that chain slings have to be flaw-tested rd after every 3 verification but at least after 3 years e.g. by means of magnetic particle testing. Chains are important safety components. Their lifting capacity is a result of each link’s resistance. Each chain link could be an uncertainly factor and a chain is only as strang as its weakest link. Magnetic particle testing essentially contributes to guarantee safety wherever chains are applied.
