IEC 60050-192:2015 gives the general terminology used in the field of dependability. The terms are generic and are applicable to all fields of dependability methodology, including electrotechnical applications. The document is not an exhaustive vocabulary for all IEC standards in the dependability field: definitions for some specialized terms may only be found in the relevant standards. This document replaces sections 1 to 20 of IEC 60050-191:1990, which has been subjected to a systematic, in-depth review and revision, in order to reflect the current usage of the terms in the dependability field, to introduce new terms from new or revised standards, and other informed sources, and to provide a grammatical form, and presentation to comply with the IEC directives. It has the status of a horizontal standard in accordance with IEC Guide 108:2006. This terminology is consistent with the terminology developed in the other specialized parts of the IEV.

This part of ISO 25178 deals with geometrical defects that may be present on the surfaces of material measures and calibration specimens conforming to ISO 5436-1 and ISO 25178-70. It defines classes of these geometrical defects, and defines terms for ways of responding to these defects.
This part of ISO 25178 is applicable as follows:
a) to help customers and users of material measures for surface metrology specify their nominal features (ideal geometrical properties) when purchasing them from manufacturers and suppliers;
b) to enable users of material measures to formulate their own rules and policies for responding to the occurrence of defects in such a way as to minimise the uncertainty of their own measurements.
c) to enable calibration laboratories and their customers to agree a common policy on how to treat defects on a material measure that has been sent for calibration;
d) to educate users of material measures about the different significance and importance of different kinds of defect;
e) for other GPS standards which make reference to the issue of selection of measuring locations, or selection of areas to be measured or to be avoided in measurement.
