Introduction

The safety standard system in the machinery field 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 of machinery or a type of safety device with a wide range of applications.

- Category B1, safety features (such as safety distance, surface temperature, noise) standards;

- Category B2, safety device (such as emergency stop device, interlock device, pressure sensitive device, protective device) standard.

— Category C standards (machinery product safety standards) specify detailed safety requirements for a specific machine or group of machines.

According to GB/T 15706, this document belongs to Class A standard.

The purpose of this document is to standardize the basic and common terminology in the field of machinery safety and to make the terminology of Class A, Class B and Class C standards consistent. Be consistent. Machinery Safety Terminology
