Paint and Painting of - Part 1: Technical Specification for Supply of Paints 3 Sample Taking and Preparation 3.1 Sampling In principle, samples are taken in the manufacturing factory by a representative of consumer. The manufacturer shall supply the staff and equipment necessary for correct rapid sampling of the paints submitted for acceptance of his own expense. Products shall be submitted in batches, which must only include those of the same kind from the same manufacturing batch. Sampling procedure shall be in strict accordance with the relevant requirements of GB 3186. 3.2 Test panels Test panels shall be prepared according to the relevant requirements of GB/T 1727. The material of base panel shall be selected according to GB/T 9271 and subjected to surface treatment or determined as per the user's requirements and actual application conditions. 3.3 Sample state regulation and test temperature and humidity According to GB/T 9278, the standard environmental condition is 23℃±2℃ in temperature and (50±5)% in relative humidity.
