NOTE The manufacturer shall not be liable if marking becomes illegible as a result of installation procedures, or of cleaning, or if fittings are painted, scratched or masked. Marking shall not cause any cracking or other damage which could affect the serviceability of the
43、assemblies. If marking is printed on the assemblies, its colour shall be set off clearly against the background.

46、t German standards dealing with the dimensions and quality requirements for polybutene (PB) fittings. The standards were largely developed on the basis of existing standards on fittings made from other plastics. Each type of bend and tee is illustrated together with an equation used to calculate the
47、 design dimension, minimum value kmin, and the same equations can be used to calculate kminfor nominal sizes not covered in this standard.
