Foreword

This standard is identical to the international standard ISO 12508:1994 Earth-moving

machinery - Operator station and maintenance areas - Bluntness of edges. Most of

Chinese earth-moving machinery standards are identical to or modified in relation to

ISO/TC 127 standards, so as to adapt to international trade, technology and economic

exchanges as soon as possible.

This standard was proposed by the Ministry of Construction of the People's Republic

of China.

This standard is under the jurisdiction of the Beijing Construction Machinery

Comprehensive Research Institute, the technical authority for machinery equipment

and vehicle standards under the Ministry of Construction.

Drafting organizations of this standard: Beijing Construction Machinery

Comprehensive Research Institute of the Ministry of Construction, Tianjin Research

Institute of Construction Machinery.

Main organizers of this standard: Jia Zhiquan, Tao Xing, Wu Runcai, Yang Yaoxi.

This standard is entrusted to the Beijing Construction Machinery Comprehensive

Research Institute of the Ministry of Construction for interpretation.

Earth-moving machinery - Operator station and

maintenance areas - Bluntness of edges
