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.

These terminology standards are sometimes ignored or inadequately taken into account by the writers of: standards, specifications, multiple-choice questionnaires for certification exams, training manuals, inspection instructions, inspection reports, etc. This also applies to trainers.

 

The non-compliance to the standardized terminology obviously leads to problems of understanding between the various representatives, which may lead to troubles or even misinterpretations.

Compliance to this requirement is of the utmost importance for trainees; we think it would be highly desirable that the training programmes include the study of the relevant terminology standards and that trainers spend some time so that good habits are taken from the very start.

Imagine the troubles of some trainees who, during their certification exam, must answer questions, the wording of which is not compliant with the current terminology standards? Confused, they may not understand the question and wrongly answer to it while they could have answered if the question had been written with standardized terms. As a result: a lower mark by a point!

Other errors of terms, which are not standardized, die hard. As an example, in the ‘70s, in France, spray cans (also called “aerosol dispensers”) were called « bombe aérosol », the word-to-word translation of which is “aerosol bomb.”

A spray can is not a “bomb” as it is not filled with explosive, nor it does comprise any detonator and/or ignition system.

The right French term for “spray can” is “générateur d’aérosol.”
