Standards and regulations
1.2 Safety of machinery in Europe
Type B standards/group standards
B standards cover all safety-related standards for various different machine types. B
standards are aimed primarily at the bodies responsible for setting C standards. They can
also be useful for manufacturers during the machine design and construction phases,
however, if no applicable C standards have been defined.
A further sub-division has been made for B standards:
● Type B1 standards for higher-level safety aspects (e.g. ergonomic principles, safety
● Type B2 standards for protective safety devices are defined for different machine types
Type C standards/product standards
C standards are product-specific standards (e.g. for machine tools, woodworking machines,
elevators, packaging machines, printing machines, etc.). Product standards list requirements
for specific machines. The requirements can, under certain circumstances, deviate from the
basic and group standards. Type C/product standards have the highest priority for machine
manufacturers who can assume that it fulfills the basic requirements of Annex I of the
Machinery Directive (automatic presumption of compliance). If no product standard has been
defined for a particular machine, type B standards can be applied when the machine is
constructed.
A complete list of the standards specified and the mandated draft standards are available on
the Internet at the following address:

Recommendation: Due to the rapid pace of technical development and the associated
changes in machine concepts, the standards (and C standards in particular) should be
checked to ensure that they are up to date. Please note that the application of a particular
standard may not be mandatory provided that all the safety requirements of the applicable
EU directives are fulfilled.
