The hose assemblies are intended for the conveying of milk, milk products, or other comestibles. The hose assemblies covered by this standard are of three basic types as defined in C5.1.1, C5.1.2 and C5.1.3, and the components described therein are to be assembled only by their manufacturer, or by an authorized fabricator/distributor. Also see Appendix F1.
