Introduction

This standard is a Class C standard GB/T 15706.1-2007 provisions.

Range GB/T 15706.1-2007 given the danger involved, hazardous situations and hazardous events associated with the severity and machinery.

If the provisions of the Class A or Class B standards the provisions of this type C standard is not the same, for the design and manufacture in accordance with the provisions of this type C standard Machines, priority should be the implementation of the C class standards.
