What is ASTM E165?
Liquid penetrant testing in ASTM refers to the ASTM E165 which is Standard Practice for Liquid Penetrant Examination for General Industry.
What is ASTM e1417?
ASTM E-1417 “Standard Practice for Liquid Penetrant Examination” governs the liquid penetrant inspection process used in manufacturing and maintenance operations. ASTM E-1417 addresses personnel requirements, equipment requirements, penetrant application, and penetrant removal methods.

What are the standards applicable to liquid penetrant testing?
ISO 3452-1:2013 specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested.
Is code for DP test?
IS 3658:1999 Code of Practice for Liquid Penetration Flaw Detection (second revision). A suitable liquid penetrant is applied to the surface of the component under examination and is permitted to remain there for sufficient time to allow the liquid to penetrant into any defects open at the surface.
What is the disadvantage of dye penetrant inspection?
With this method, only surface breaking defects can be detected. It is possible to inspect only materials with relatively nonporous surface. It is necessary to pre-clean the material since contaminants can mask defects.
What is the disadvantage of the liquid penetrant test?
Liquid penetrant testing has the following disadvantages: Extensive, time-taking pre-cleaning critical—surface contaminants can mask defects. Sensitive to surface-breaking defects only. Direct connection to the surface under test necessary.
What Cannot be inspected by DPT?
We can only detect any surface discontinuity (or irregularity) such as surface cracks, porosity, pinholes, etc. by this test method. Principle: DPT is based on the principles of CAPILLARY ACTION.
What is PT in welding?
Liquid Penetrant Testing (PT) is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
What is dye penetrant testing used on?
Dye Penetrant Inspection (DPI) is widely used to detect surface breaking flaws. This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities.
