General Requirements5.1 The sample shall show no drainage of liquid and benoncaking and free flowing.Amoisture content of less than 0.5weight % is required to meet the free-flowing characteristics ofa cullet that is

8、 predominantly of smaller particle size, 1.18-mm(No 16) sieve or smaller.5.2 Screen SizeNo material shall be retained on a 6-mm(14-in.) screen. Material not exceeding 15 weight % shall passthrough a 106-m (No. 140) screen.5.3 Organic MaterialsThe total content of organic mate-rials, as measured in a

9、ccordance with Section 6 shall notexceed 0.2 weight % of dry sample, except for color-mixedglass where the content of organic material may exceed 0.2weight %. However, a content of organic material greater than0.2 weight % must be held within a tolerance of 60.05weight %, with a maximum organic limi
