This Part is Part 2 of GB/T 15706.
This part is identical to ISO 12100-2.2003, Safety of machinery – Basic concepts,
general principles for design – Part 2. Technical principles; some editorial changes are
made in accordance with the rules for drafting standards in China as specified in GB/T
1.1-2000.
This Part replaces GB/T 15706.2-1995, Safety of machinery – Basic concepts, general
principles for design – Part 2. Technical principles and specifications.

The previous edition of the standard replaced by this Part is as follows.
-- GB/T 15706.2-1995.
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.
type-B1 standards on particular safety aspects (e.g. safety distances, surface
temperature, noise);
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.
