1 Scope This part of ISO 5630 specifies a method for accelerating the ageing of paper and board through exposure to an elevated light irradiance and for assessing the effect of ageing on optical properties for the purpose of predicting stability to long-term natural ageing that occurs due to exposure to light. It is applicable to all types of paper and board whose surface is white or near white.
