The four methods are listed below:
- Method A – Water Washable.
- Method B – Post-Emulsifiable, Lipophilic.
- Method C – Solvent Removable.
- Method D – Post-Emulsifiable, Hydrophilic.
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.
Which type developer shall not be used with type II penetrant?
1 Forms a and b (dry powder and water soluble) developers shall not be used with Type II (visible dye) penetrant systems.
Which level of penetrant is most sensitive?
Understand fluorescent liquid penetrant sensitivity levels and how to find the right one for your application
- Level ½ – Very low sensitivity.
- Level 1 – Low sensitivity.
- Level 2 – Medium sensitivity.
- Level 3 – High sensitivity.
- Level 4 – Ultrahigh sensitivity.
How many types of penetrant are there?
three basic types of penetrant: Colour contrast. Fluorescent. Dual purpose (fluorescent / colour contrast)
What penetrant means?
(Entry 1 of 2) 1 : penetrating. 2 of a gene : producing a phenotypic effect : exhibiting penetrance.
What are the standards applicable to liquid penetrant testing?
List of Standards for Dye Penetrant Inspection
| Sr. | Number | Title |
|---|---|---|
| 15 | ASTM E 1417 | Standard Practice for Liquid Penetrant Testing |
| 16 | ASME BPV Section V Art.6 | Liquid Penetrant Examination |

What is ASTM 709?
Magnetic particle users outside the aerospace industry have typically used ASTM E709 Standard Guide for Magnetic Particle Testing as their baseline standard for procedures. ASME, AWS, and API standards all use ASTM E709 as a reference to build their specific requirements.
Which developer is most sensitive?
Nonaqueous developers are generally recognized as the most sensitive when properly applied. There is less agreement on the performance of dry and aqueous wet developers, but the aqueous developers are usually considered more sensitive.
What do you mean by developers and what are its types?
In the IT world, a developer is a person who creates something with a computer. The term encompasses many types of content, such as software, websites, and written material. Therefore, developers are often referred to by more specific names.
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.
How do I check my DPT?
The penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed and a developer is applied. The developer helps to draw penetrant out of the flaw so that an invisible indication becomes visible to the inspector.
What do the numbers mean in ASTM e1417?
ASTM E1417 / E1417M – 16. An ASTM designation number identifies a unique version of an ASTM standard. E1417 / E1417M – 16. E = miscellaneous subjects; 1417 = assigned sequential number. M = SI units. 16 = year of original adoption (or, in the case of revision, the year of last revision)
Which is FPI According to ASTM e1417-ndt?
Re: FPI according to ASTM E1417 In Reply to Dislocation at 16:46 May-10-2016 (Opening). According with ASTM E 1417, it recommends that you should be using sensitivity level III or IV for turbine engine components.
Which is ASTM standard practice for liquid penetrant testing?
