United Kingdom Repealed

1. (a)Spreading rate: White paints and light-coloured paints (including finishes, primers, undercoats and/or intermediates) shall have a spreading rate (at a hiding power of 98 %) of at least 6 m2 per litre of product.
2. (b)Resistance to water: Varnishes, floor coatings and floor paints shall have a resistance to water, as determined by ISO 2812-3 such that after 24 hours' exposure and 16 hours' recovery no change of gloss or of colour occurs.
3. (c)Adhesion: Masonry paints (excluding transparent primers) shall score a pass in the EN 24624 (ISO 4624) pull-off test for adhesion and floor coatings, floor paints and undercoats for concrete, wood and metal coatings shall score at least a 2 in the EN 2409 cross-cut method for adhesion. When carrying out EN 24624 where the cohesive strength of the substrate is less than the adhesive strength of the paint then this is considered a pass, otherwise the adhesion of the paint must be in excess of a pass value of 1,5MPa.
4. (d)Abrasion: Floor coatings and floor paints shall have an abrasion resistance not exceeding 70 mg weight loss after 1 000 test cycles with a 1 000 g load and a CS10 wheel according to EN ISO 7784-2:2006.
5. (e)Weathering: Masonry finish paints and wood and metal finishes including varnishes shall be exposed to artificial weathering in apparatus including fluorescent UV lamps and condensation or water spray according to 11507:2007. Masonry paints shall be exposed to test conditions for 1 000 hours, wood and metal finishes (including varnishes) shall be exposed to test conditions for 500 hours. Test conditions are: UVA 4h/60degC + humidity 4h/50degC.
6. (f)Water vapour permeability: Where claims are made that exterior masonry and concrete paints are breathable the paint shall be classified as Class II (medium vapour permeability) or better according to the test method EN ISO 7783-2. Due to the large number of potential tinting colours, this criterion will be restricted to testing of the base paint; this requirement is not applicable to transparent primers.
7. (g)Liquid water permeability: Where claims are made that exterior masonry and concrete paints are water repellent or elastomeric, the coating shall be classified as Class III (low liquid permeability) according to method DIN EN 1062-3:1999. Due to the large number of potential tinting colours, this criterion will be restricted to the testing of the base paint. All other masonry paints shall be classified as Class II (medium liquid permeability) or better according to the test method DIN EN 1062-3:1999.
8. (h)Fungal resistance: Where claims are made that masonry finish coatings have anti-fungal properties, the coating shall have a score of 2 or better (less than 10 % fungal coverage), as determined by method BS 3900:G6. Due to the large number of possible tinting colours, this criterion will be restricted to the testing of the base paint.
9. (i)Crack bridging: Where claims are made that masonry (or concrete) paint has elastomeric properties, it shall be at least classified as A1 at 23 °C according to DIN EN 1062-7:2004. Due to the large number of potential tinting colours, this criterion will be restricted to the testing of the base paint.
10. (j)Alkali resistance: Masonry paints and primers shall show no noticeable damage when the coating is spotted for 24 hours with 10 % NaOH solution according to method ISO 2812-4:2007.The evaluation is done after 24 hours drying-recovery.
