March / April / May 2016 : Electrical heaters in the dust storm cabinet
The ISO 3452-4:1998 standard, quite old, though still enforced, requires that the dust storm cabinet be fit with a heater, to prevent any contamination of the powder by the air moisture.
December 2015 / January / February 2016 : MT detection media: Should we talk about their detection sensitivity or their ability to detect discontinuities?
The penetrant systems (product families) are qualified after determining their sensitivity levels according to the ISO 3452-2 standard, when using the Type 1 reference blocks of the ISO 3452-3 standard.
They may also be qualified according to the SAE-AMS 2644 American specification.
September / October / November 2015 : Solvent-based developer or non-aqueous wet developer ?
We have already devoted many editorials to the terminology used in penetrant testing (PT) and magnetic particle testing (MT).
We always recommend that the authors of standards, specifications, training courses, multiple-choice questionnaires and any other document comply with the terminology, so that everyone can understand each other.
June/July/August 2015 : Terminology discrepancies between ISO and ASTM standards
In our December 2013 Editorial(1), we reported that with regard to penetrant testing (PT) and magnetic particle testing (MT), there were some differences between the EN/ISO standards and the ASTM E1316 standard and we provided some examples.

December 2014 - January 2015 : Using the standard terminology in non-destructive testing : A good idea
There are a large number of standards dealing with the terminology in non-destructive testing (NDT).
For example, some of these standards are listed in the section titled “Normative references” at the end of this paper.
Furthermore, some standards may mention definitions that do not appear in the terminology standards, such as the ISO 3452-2:2013, Non-destructive testing -- Penetrant testing -- Part 2: Testing of penetrant materials, in chapter 3, titled “Terms and definitions”, or in the ASTM E1417/E1417M - 13 standard, Standard Practice for Liquid Penetrant Testing, in chapter 3, Terminology, paragraph 3.2 Definitions of Terms Specific to This Standard.
September-October 2014 : Nondestructive examination, Nondestructive testing and Nondestructive inspection
What is the difference between Nondestructive Examination and Nondestructive Inspection?
These terms are not defined in the EN 1330-1 and 1330-2 standards.
