Introduction
In 1980, a number of areas of work for improving the methods of assessing changes in appearance of textile
floor coverings were agreed, including experiments aimed at developing the use of sets of fatigued specimens
as reference scales to assist in the assessment of the changes. Conclusions drawn from the results of inter-
laboratory trials indicated that carefully selected reference scales aided the assessment of appearance
changes in textile floor coverings. However, members expressed concern over the widespread introduction of
procedures based on reference scales because of possible problems such as constancy of production and
stability in use.
Further work was requested before the method was to be published as a full International Standard and a
Technical Report (type 2) describing the procedures for using reference scales to assist in the overall
assessment of appearance change was published in 1990. Subsequently a modified version of the
assessment procedure was adopted by CEN and has been published as EN 1471.
In 1996 ISO/TC 38 SC 12 decided to develop TR 9405 into a full International Standard describing the best
available method of subjective visual assessment of appearance retention testing. The first Draft International
Standard (DIS) reflected the progress made by both the CEN and ISO committees and the DIS.2 reflected
further progress in that it introduced the option of using digital image reference scales as an alternative to the
carpet sample reference scales.
Following assessments of the digital image reference scales by a number of laboratories in Europe and North
America, ISO/TC 38 SC 12 decided, in its meeting in November 1999 to issue for approval a Final Draft
International Standard (FDIS) in which the digital images were the only reference scales.
Assessments of the digital image reference scales by a number of laboratories in Europe, ISO/TC 219 WG1
decided, in its meeting in February 2012 to issue for approval a Draft International Standard (DIS) in which the
digital images were the only reference scales, only 3 scales will be used.
Nowadays we have seen that the evaluations we evolve with a new method, because of the use of the digital
scales.
