1 Scope
This standard specifies the outlined details of safety of machinery standards.
This standard may help the designers and manufacturers of machinery and associated equipment, particularly where specific Category C standard is unavailable, to correctly understand relevant safety of machinery standards.
Note: this standard does not cover the contents of Category C standards.
2 Classification of Safety of Machinery Standards
2.1 Category A standards (fundamental safety standards)
Providing fundamental concepts, design principles and general characters which are universally applicable to all machinery. See Table 1 for relevant standards.

3 Basic Concepts, Principles and Requirements
Figure 2~Figure 5 give basic approaches to safety of machinery including the idea of reducing risk by protection measures (e.g. safety function), iterative method of risk assessment/risk reduction, and selection of and validation of safety functions (safety-related parts of control system). The basic procedures of risk assessment processes are given inside the boxes on the top left corners of Figure 2 and Figure 4, as detailed in GB/T 15706-2012. Figure 3 illustrates the idea of reducing risk by protection measures including safety function (safety-related parts of control system). Figure 4 illustrates a basic procedure of risk reduction, as detailed in Figure 1 of GB/T 15706-2012. Figure 5 illustrates the validation process with the safety-related parts of control system determined as protection measure.
The other parts of this standard provide the risk reduction measures to be undertaken by the manufacturer:
1) Intrinsic safety design measure;
2) Safety protection and supplementary protection measures;
3) Information for use
See 6.4 of GB/T 15706-2012, Chapter 6 of GB/T 16856.2-2008 and Chapter 11 of this standard for details of information for use.
