Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer. This standard does not contain acceptance standards or recommended quality levels. There were no books found for the applied search filters. Specify standard, Type of dye, Method, and Sensitivity Usage: The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other.

Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Copyright Compu-tecture, Inc.

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.

Magnetic particle examination is not applicable to nonferromagnetic metals and alloys.

However, false indications may be produced by localized surface irregularities, metallurgical discontinuities, or magnetic permeability variations. Combining values from the two systems may result in a nonconformance with this speci?

The penetrant examination processes a90 in this practice are applicable to in-process, final, and maintenance in-service inspections. These nondestructive testing NDT methods include: These processes are applicable for the detection of discontinuities, such as lack of fusion, corrosion, cracks, laps, cold shuts, and porosity, that are open or connected aastm the surface of the component under examination.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Asm penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer.

When agreed upon between the manufacturer and purchaser, the liquid penetrant method may be used to verify the presence of surface discontinuities which had been previously indicated by the magnetic particle method. Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. Evaluation of Indications 6. This test method provides a procedure w903 magnetic particle examination of steel forgings.
