Work Item s – proposed revisions of this standard. This might involve sandblasting, wire brushing, etc.

As soon as the material is dry, the developer is applied. Penetrating oils typically contain a red dye and are sprayed or brushed onto the area of the material being tested.

The correct e16-02 for a discontinuity is an indication, which is not necessarily a crack or a flaw. This method substitutes fluorescent penetrating oil for the visible dye penetrant.

Link to Active This link r165-02 always route to the current Active version of the standard. One of the most critical aspects of liquid penetrant testing is interpreting and evaluating the discontinuities. Non-destructive examination basics Patrick J. Non-destructive examination NDE is used to detect cracks and other flaws in a part without rendering the part unusable by performing destructive testing. Agreement by the user and the supplier regarding specific techniques is strongly recommended.

These inspections can increase the reliability of the part by providing early detection of flaws that could lead to a failure.

Cracks typically show up as red lines and pits usually look like red dots. r165-02

ASTM E – 02 Standard Test Method for Liquid Penetrant Examination

Some equipment manufacturers allow some surface indications, depending on their size and location on a particular part. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Pre-clean the surfaces to be inspected.

Then the surface must be allowed to dry. Care must be taken not to overly clean and remove the penetrant from the discontinuities. A scratch or a pore can easily be misinterpreted as a crack or flaw, and this can lead to e165-022 and costly repairs.

Energy-Tech Magazine Contact us. Some of the most popular NDE methods include: A suitable waiting time allows the penetrant to enter the surface discontinuities, and then excess penetrant can be removed. This is typically done with a special cleaning solvent. The surface then needs to be solvent cleaned to remove any greases or oils. The purpose of this article is to describe these basic NDE techniques and discuss some of the advantages and disadvantages of the different methods.

They are nondestructive testing methods for detecting discontinuities that are open to the surface such as cracks, seams, laps, cold shuts, laminations, through leaks, or lack of fusion and are applicable to in-process, final, and maintenance examination.

Another technique involves the use of an ultraviolet light to view the surface discontinuities. They can be effectively used in the examination of nonporous, metallic materials, both ferrous and nonferrous, and of nonmetallic materials such as glazed or fully densified ceramics, certain nonporous plastics, and glass.

It is a common misconception to label a discontinuity as a crack. Liquid penetrant e16502 Liquid penetrant astj is the most popular method to check for surface cracks because it is simple and no special equipment is required.

The part then needs to be cleaned to remove the penetrant and the developer. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For this purpose there must be a separate code or specification or a specific agreement to define the type, size, location, and direction of indications considered acceptable, and those considered unacceptable.

The liquid penetrant examination just makes the discontinuities easier to see.

To w165-02 this, any indications should be investigated by polishing and re-evaluating the indication. Box Dubuque, IA Phone: It should be pointed out, however, that after ee165-02 have been produced, they must be interpreted or classified and then evaluated.

This can take minutes after the developer is applied. The penetrant that is trapped in any discontinuities will glow when viewed under a black light. The reason is that some potable water sources contain chlorine, which can leave a s165-02 on the surface and can lead to cracking in some stainless steels.

Also, there are no universal acceptance criteria on the maximum allowable size of an indication. With this technique, liquid penetrant is applied to the surface of a material and is drawn into surface discontinuities such as cracks, pits and seams by capillary action.

Active view current version of standard. After application of the ashm, the visual inspection is done with a black light. In most cases, the discontinuities are visible to the naked eye without e615-02 penetrant testing. The visible dye penetrant technique involves the following steps: This technique can be used on a variety of ferrous and non-ferrous materials, including steel, stainless steel, aluminum, bronze, tungsten carbide, ceramics and plastics.

A common recommendation is to use solvent and not potable water when cleaning stainless steel parts, such as turbine rotors, that will be highly stressed when in service.
