6.4 Sampling method
6.4.1 Sampling method for type inspection
Type inspection
Factory inspection
The finished products of the same variety and grade are considered as a batch. If the quantity is less than 200t, it is also considered as a batch. Ten samples are randomly selected from different parts of each batch, and each sample should not be less than 10kg. Mix them evenly and use the quartering method to take samples that are twice the test quantity as the sample. 6.4.2 Sampling and numbering for factory inspection
6.4.2.1FA binders should be sampled according to the same type and grade before leaving the factory. Bagged FA binders and bulk FA binders should be numbered and sampled separately, and each number is a sampling unit.
6.4.2.2 The number of numbers does not exceed 300t and the output does not exceed 3d as one number. 6.4.2.3 Sampling should be representative and can be taken continuously or from more than 20 different parts with a total amount of at least 12kg. 1kg each time, 10kg is enough as a test batch sample.
6.4.4.4 FA binders leaving the factory must be inspected and qualified by the factory quality inspection department, and attached with a test sheet. According to the factory inspection items, if one indicator is unqualified, it is an unqualified product. Packaging, marking, transportation and storage
7.1 Packaging
Engineering Construction Standard Full Text Information System
bzsosO.comEngineering Construction Standard Full Text Information System
FA binder can be packed in bags or in bulk. The net weight of each bag of bagged FA binder is 50kg, and shall not be less than 98% of the marked weight. Randomly sample 20 bags, the total weight of FA binder shall not be less than 1000kg. Other packaging forms shall be determined by negotiation between the supply and demand parties, but the bag weight requirements must comply with the above principles. FA binder packaging bags shall comply with the provisions of GB9774. 7.2 Marking
FA binder bags shall be clearly marked with: factory name, product name, registered trademark, grade (M7.5 and above grades are printed in red, M5.0 and below grades are printed in green), packaging year, month, day and number. When in bulk, a card with the same content as the bagged mark shall be submitted. 7.3 Transportation and storage
FA binders must not be exposed to moisture or mixed with foreign matter during transportation and storage. Different grades of FA binders should be stored separately and must not be mixed.
