Introduction
The standard system in the field of mechanical safety consists of the following categories of standards.
--- Category A standards (basic safety standards) give basic concepts, design principles and general characteristics applicable to all machinery.
--- Category B standards (general safety standards) involve a safety feature in a machine or a type of safety device with a wider range of use.
● Category B1, safety features (such as safety distance, surface temperature, noise) standards;
● Category B2, safety device (such as two-hand control device, interlocking device, pressure sensitive device, protective device) standards.
---C-type standards (machinery product safety standards) are standards that specify detailed safety requirements for a specific machine or a group of machines.
According to GB/T 15706, this document belongs to Class B standard.
This document is particularly relevant to the following stakeholders involved in machinery safety.
---Machine manufacturer;
---Health and safety agencies.
Other stakeholders affected by the level of machinery safety are.
---Machine users;
---Machine owner;
---Service providers;
--- Consumer (for machinery intended for use by consumers).
All the above stakeholders can participate in the drafting of this document.
Furthermore, this document is intended for use by standardization bodies drafting Type C standards.
The requirements specified in this document may be supplemented or modified by Type C standards.
For machines that are within the scope of Category C standards and have been designed and manufactured in accordance with Category C standards, the requirements of Category C standards should be adopted first.
This document provides guidance to machine users on the control of hazardous energy in the machine's power system under various interacting conditions.
