通告描述：

This Draft Rwanda Standard provides the common requirements, sampling and test methods for unreinforced, reinforced and prestressed precast concrete products made of compact light, normal and heavyweight concrete according to RS ISO 22965 with no appreciable amount of entrapped air other than entrained air. It may also be used to specify products for which there is no standard. Not all of the requirements (Clause 5) of this standard are relevant to all precast concrete products. If a specific product standard exists, it takes precedence over this standard. The precast concrete products dealt with in this standard are factory produced for building and civil engineering works. This document can also be applied to products manufactured in temporary plants on site if the production is protected against adverse weather conditions and controlled. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure. The analysis and design of precast concrete products is not within the scope of this document.
