1 subject content and scope of application

this standard specifies the technical requirements, test methods and inspection rules of paper bags for cement packaging (hereinafter referred to as paper bags) and composite bags for cement testing (hereinafter referred to as composite bags)

this standard is applicable to paper bags and composite bags

2 reference standard (omitted)

3 type and code

3.1 cement packaging bags are divided into paper bags and composite bags, each of which is divided into 50 types and 45 types according to the weight of packaged cement, and each type of

is divided into several categories according to the effective length, of which each type of composite bags is divided into three temperature grades according to the applicable temperature

3.2 the code of paper bag for cement packaging is zdxx - XXX, and the code of composite bag for cement packaging is fdxx - XXX - XXX. Among them, from left to right is the bag name, ZD represents paper bag, FD represents composite bag; The first group of numbers represents the model; The second group of numbers represents the effective length (in mm); The third group of digits of the composite bag is the applicable temperature (℃). The specific expression method of

is shown in Table 1
