Introduction

The primary purpose of GB/T 15706 is to provide designers with an overall framework

and guidance to enable them to produce machines that are safe for their intended use.

It also provides a strategy for standard makers.

The concept of safety of machinery considers the ability of a machine to perform its

intended function(s) during its lifecycle where risk has been adequately reduced.

This standard is the basis for a set of standards which has the following structure.

-- type-A standards (basic safety standards) giving basic concepts, principles for

design, and general aspects that can be applied to all machinery;

-- type-B standards (generic safety standards) dealing with one safety aspect or one

type of safeguard that can be used across a wide range of machinery.

nu type-B1 standards on particular safety aspects (e.g. safety distances, surface

temperature, noise);

nu type-B2 standards on safeguards (e.g. two-hand controls, interlocking

devices, pressure sensitive devices, guards);

-- type-C standards (machine safety standards) dealing with detailed safety

requirements for a particular machine or group of machines.

This standard is a type-A standard.

The subject of numerous clauses or subclauses of this standard is also dealt with, in a

more detailed manner, in other type-A or B standards.

When a type-C standard deviates from one or more provisions dealt with by Part 2 of

this standard or by a type-B standard, the type-C standard takes precedence.

It is recommended that this standard be incorporated in training courses and manuals

to convey basic terminology and general design methods to designers.

Safety of machinery – Basic concepts, general

principles for design – Part 2. Technical principles

1 Scope

This standard defines technical principles to help designers in achieving safety in the

design of machinery.

GB/T 15706.2 is intended to be used together with GB/T 15706.1 when considering

the solution to a specific problem. The two parts of GB/T 15706 can be used

independently of other documents or as a basis for the preparation of other type-A

standards or type-B or -C standards.

This standard does not deal with damage to domestic animals, property or the

environment.
