Standards on the metal magnetic memory method

ISO 24497-1:2007(E)

Non-destructive testing – Metal magnetic memory – Part 1: Vocabulary

Publication date November 01, 2007

Scope

This part of ISO 24497 specifies terms and definitions for procedures in the sphere of non-destructive testing by the method of metal magnetic memory.

The terms specified in this part of ISO 24497 are mandatory for application in all types of documentation and literature in the sphere of non-destructive testing, using the method of metal magnetic memory included in the scope of standardization works and/or using the results of these works.

ISO 24497-2:2007(E)

Non-destructive testing – Metal magnetic memory – Part 2: General requirements

Publication date November 01, 2007

Scope

This part of ISO 24497 specifies the general requirements for the application of the method of metal magnetic memory of components, units, equipment and structures for various application purposes. It covers non-destructive testing.

The purposes of the method are the following:

  • Determination of heterogeneity of the stress/strain state of equipment and structures and revealing of stress concentration zones as the main sources of damage.
  • Determination of locations to perform metal sampling in stress concentration zones for assessment of the microstructural-mechanical state.
  • Early diagnostics of fatigue damage and evaluation of equipment and structure life.
  • Reduction of testing and material costs with its utilization in combination with conventional methods of non-destructive testing.
  • Quality control of welded joints of various types and embodiment (including contact and spot welding).
  • Very quick sorting of new and used machine-building products by their microstructural heterogeneity.

ISO 24497-3:2007(E)

Non-destructive testing - Metal magnetic memory - Part 3: Inspection of welded joints

Publication date November 01, 2007

Scope

This part of ISO 24497 specifies the general requirements for the application of the metal magnetic memory inspection method (ММM inspection) as a non-destructive testing method for quality assurance of welded joints of pressurized components.

This part of ISO 24497 may be applied to welded joints in any type of products, pipelines, vessels, equipment and metal constructions, as agreed with the purchaser.

The terms and definitions for the process are contained in ISO 24497-1, and the general requirements of the process are in ISO 24497-2.

GOST R 52330-2005

State Standard of Russian Federation. Non-destructive Testing. Evaluation of Deformations in Industrial and Vehicle Structures. General Requirements

Introduction date September 01, 2005

Scope

This standard specifies general requirements to application of methods and means of non-destructive testing of stress-strained state on industrial objects and transport.

GOST R 53006-2008

State Standard of Russian Federation. Estimation of Potential Dangerous Objects Lifetime on the Basis of Express Methods. General Requirements

Introduction date September 01, 2009

Scope

This standard covers the objects (various-purpose pipelines, vessels and structures and their elements, including the welded joints of any structural configuration) with exhausted specified (by the manufacturer) design lifetimes, which require the assessment of lifetime characteristics before the expiry of the specified service life, as well as the objects after emergencies and renewals.

This standard specifies the basic requirements to the contents of techniques and standards regulating the procedures of the residual lifetime assessment of the potentially dangerous technical objects with application of non-destructive quick methods of the engineering diagnostics.
