DESCRIPTION
BS ISO 23169:2020
This standard BS ISO 23169:2020 Paints and varnishes. On-site test methods on quality assessment for interior wall coatings is classified in these ICS categories:
- 87.040 Paints and varnishes
This document specifies two on-site test methods (on-site cleanability [stain removal] and on-site wet-scrub resistance) for the evaluation of the quality assessment for interior wall coatings.
These test methods are applicable to white coatings and light-coloured coatings of tristimulus value Y10 greater than 25 measured on a test specimen consisting of a coating applied to a black substrate.
The cleanability test can differentiate the coating quality between 18 % of the pigment volume concentration (PVC) and the critical pigment volume concentration (CPVC). The on-site wet-scrub resistance test method can differentiate the coating quality when the PVC is nearly equal to the CPVC or above.
