EN 982:1996+A1:2008

Safety of machinery - Safety requirements for fluid power systems and their components - Hydraulics

This standard is a type B2 standard (according to EN 292-1) and contains the general requirements for hydraulic systems and their components on machinery. For type C standard makers, it is a basis for the development of specific requirements on dedicated machines. If no type C standards are available, it is a basis for the manufacturers when constructing machines that include hydraulic systems and their components.
In developing this standard, safety related requirements out of ISO 4413 were selected as well as additional safety related requirements.
Equivalent safety requirements for pneumatic systems are defined in EN 983 "Safety of machinery - Safety requirements for fluid power systems and their components - Pneumatics".

Introduction
This standard is a type B2 standard (according to EN 292-1) and contains the general requirements for
hydraulic systems and their components on machinery. For type C standard makers, it is a basis for the
development of specific requirements on dedicated machines. If no type C standards are available, it is a
basis for the manufacturers when constructing machines that include hydraulic systems and their
components.
In developing this standard, safety related requirements out of ISO 4413 were selected as well as additional
safety related requirements.
Equivalent safety requirements for pneumatic systems are defined in EN 983 "Safety of machinery – Safety
requirements for fluid power systems and their components – Pneumatics".
1 Scope
This standard applies to hydraulic systems and their components on machinery. It identifies hazards and
factors which affect the safety of systems and their components when they are put to their intended use.
The principles specified apply to the design, construction and modification of new systems and their
components and aspects of use including:
 Assembly
 Installation
 Adjustment
 Operation
 Cleaning
 Maintenance.
Components are covered in the standard but only to the extent that safety requirements are given to allow the
components to be safely integrated into a system's design.
The standard applies to systems and their components on machinery that are manufactured after the date of
the adoption of this standard.
