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. However, asfm indications may be produced by localized surface irregularities, metallurgical discontinuities, or magnetic permeability variations. The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components.

Nondestructive testing methods discussed are Liquid Penetrantand Magnetic Particle. Within the text the SI units are shown in brackets.

It is useful for preventive maintenance examination. Specify standard, Type of dye, Method, and Sensitivity Usage: This abstract is a brief summary of the referenced standard. This specification covers acceptance criteria for the surface inspection of steel castings when nondestructively examined by magnetic particle or liquid penetrant inspection. Are you sure you want to empty the cart? Current satm approved Oct.

Only direct current or rectified alternating full or half wave current shall be used as the electric power source for any of xstm magnetizing methods. Magnetic particle examination may be applied to aa903 material, semifinished material billets, blooms, castings, and forgingsfinished material and welds, regardless of heat treatment or lack thereof. Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Abstract This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. If you like to setup a quick demo, let us know at support madcad. No attempt has been made to establish limits of acceptability or the metallurgical cause of a discontinuity. These nondestructive testing NDT methods include: Actual dimensions including maximum length of indications and number of indications per unit area must be specified by the users of this document.
