33、n millimetres, of the two measurements of the length, L, made along the lateral edges on a bag. Pm, is the arithmetic mean, expressed in millimetres, of the two measurements of the width, P, made, at the top and bottom, on a bag. Sm, is the half arithmetic mean, expressed in millimetres, of the two

34、measurements of the width of gusset, 2S, made each side on a bag. EN 14867:2005 (E) 8 Z is a value, expressed in mm, taking into account the closure system, (see Figure 1): Z = 0 for bags with zipper; Z = 30 for bags with tie closure (reservation for tying). NOTE The effective volume is not related

35、to the permissible load. 4.1.2 Requirements The supplier shall declare the nominal width Pnand the nominal length Ln, expressed in millimetres. When tested in accordance with test methods as specified in Table 1, the plastics freezer bag shall have dimensional characteristics conforming to the requi
