This standard applies to profiles in the colour range: L * => 82 (chromaticity co-ordinate Y => 60) - 2,5 <= a* <= 5 - 5 <= b* <=15 when determined according to ISO 7724-3 with the apparatus according to ISO 7724-1 and ISO 7724-2 with the following specifications: - employing CIE Standard illuminant D65 including specular reflectance; - measuring condition 8/d or d/8 (without gloss trap for both). NOTE Profiles in accordance with this standard are capable of making durable windows and doors, taking into account factors such as climatic conditions, design, methods of fabrication and long term performance.
