43、 without providing a physical barrier. The objective of this specification is to assist: standards writing committees responsible for developing machine standards (“C“ Standards), machine designers, manufacturers and refurbishers, machine safety certification organizations, workplace authorities and

44、 others on the proper application of protective equipment to machinery. Figures 1 and 2 show the general context and the intended use of this specification. Clauses 1 to 5, 7 and 8 of this specification apply to all protective equipment included in the scope, Clause 6 contains guidance for the appli
