Introduction
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
1 Scope
This document specifies requirements and test methods for sensitive protective equipment put
separately on the market as safety components to be used with entrance equipment such as power
operated industrial, commercial and garage doors, gates and barriers, power operated pedestrian doors
and power operated pedestrian entrance control equipment.

Note 1 to entry: Fixed blanking is a technique wherein the locations of the blanked areas of the detection zone do
not change during operation. The detection capability of the other parts of the detection zone remains unchanged.
Note 2 to entry: Floating blanking is a technique wherein the blanked area of the detection zone follows the location
of a moving object(s) during operation. The detection capability of the other areas remains unchanged.

safety extra-low voltage
voltage not exceeding 42 V between conductors and between conductors and earth, the no load voltage
not exceeding 50 V. When safety extra-low voltage is obtained from the supply mains, it is to be through
a safety isolating transformer or a convertor with separate windings, the insulation of which complies
with double insulation or reinforced insulation requirements

4 List of significant hazards
4.1 General
This clause contains all the hazards, hazardous situations and events identified by risk assessment as
significant for this type of machinery and which require action to eliminate or reduce the risk.
Annex C is giving the relationship between the hazards listed in this clause, the safety requirements
and/or protective/risk reduction measures given in Clause 5 and the verification methods described in
Clause 6.
4.2 Hazards caused by fixing
Inadequate fixing of the protective equipment or parts of it can impair the protective function or cause
hazards because of falling objects.
4.3 Hazards caused by the shape
Shape of the protective equipment or parts of it can cause cutting hazards.
4.4 Hazards caused by use of energy
Use of energy for the powered operation of the protective equipment can lead to hazards. This includes
electrical, hydraulic and pneumatic energy.
4.5 Hazards generated by optical radiation
Photobiological hazards can arise from the radiation intensity of light waves (e.g. laser beams, LED).
4.6 Hazards caused by out of range wavelength of the optical detection technology
Hazardous operation can arise from use of a wavelength outside the specified range.
4.7 Hazards caused by the loss of the safety function
4.7.1 Loss of the sensing function because of temperature and humidity
Temperature and humidity can impair the proper functioning of the protective equipment.
4.7.2 Loss of the sensing function because
