BS EN ISO 12100-1:2003 pdf free.Safety of machinery — Basic concepts, general principles for design — Part 1: Basic terminology, methodology.
The primary purpose of ISO 12100 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-BI 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.
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.
ISO/IEC Guide 51 has been taken into account as far as practicable at the time of drafting of this standard.
1 Scope
This standard defines basic terminology and methodology used in achieving safety of machinery.
The provisions stated in this standard are intended for the designer.
This standard does not deal with damage to domestic animals, property or the environment.

3.1
machinery
machine
assembly of linked parts or components, at least one of which moves, with the appropriate machine actuators, control and power circuits, joined together for a specific application, in particular for the processing, treatment, moving or packaging of a material.
The terms “machinery” and “machine’ also cover an assembly of machines which, in order to achieve the same end, are arranged and controlled so that they function as an integral whole.
NOTE Annex A provides a general schematic representation of a machine.
3.2
reliability (of a machine)
ability of a machine or its components or equipment, to perform a required function under specified conditions and for a given period of time without failing
3.3
maintainability (of a machine)
ability of a machine to be maintained in a state which enables it to fulfil its function under conditions of intended use, or restored into such a state, the necessary actions (maintenance) being carried out according to specified practices and using specified means.BS EN ISO 12100-1:2003 pdf free download.
