ISO/IEC Guide 46:1985
Comparative testing of consumer products and related services -- General principles
This standard has been revised by ISO/IEC Guide 46:2017
The principles are applicable to consumer products, services and a combination of both. They may usefully be followed by bodies and associations which conduct comparative testing programmes. The purpose of this Guide is to enable meaningful test results and information to be presented in a way which will help consumers and others to make an informed choice suitable to their own needs. The notes offer some but not all the means of applying the principles.
