The following limits shall be for joins within a single reel: diameter 700 mm, no more than 1 join; diameter$ 700 mm, no more than 2 joins. Where required the percentage of join free
30、reels within an order shall be agreed between customer and supplier. 3.4 Surface and edge debris The paper shall be essentially free from dust, loose fibres and debris. 4 Sampling and conditioning The samples shall be taken in accordance with EN ISO 186. The samples from which the specimen will be t

Moisture content shall be tested directly on the paper as supplied. 5 Packaging 5.1 Reels All reels leaving the paper mill sh
32、all be fully protected against fluctuations in weather conditions and the reels should remain in their protective packaging until they are to be used. Before processing the wrapped reels shall be stored in an area sharing the same atmospheric conditions as the processing equipment to allow them to r

The boxes or reels shall be stored out of direct sunlight, away from components of heating systems and not direc
34、tly on the floor. 6 Attainment of thermal equilibrium between storage area and printing room Before the paper is used in the printing room thermal equilibrium shall be attained. The required time for this depends upon the quantity of paper involved and the atmospheric conditions (see Table 2).blankB
