Provides the means for evaluating the characteristics of operator protective guards for use on hydraulic excavators, and prescribes the performance requirements of a representative sample under loading. This Standard is identical with and has been reproduced from ISO 10262:1998.

This International Standard establishes a consistent, repeatable test procedure and performance requirements for evaluating operator-protective guarding that undergo loading. Such guards are usually intended to provide excavator operators with reasonable protection against objects (e.g. rocks and debris) which would otherwise penetrate the operators station from the front or top.It is applicable to hydraulic excavators, as defined in ISO 7135 when equipped with an operator's station guard(s).
