This Standard specifies additional requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function.

Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved.

An ESPE may include optional safetyrelated functions, the requirements for which are given both in Annex A of this Standard and in Annex A of part 1.

This Standard does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine.

It is restricted to the functioning of the ESPE and how it interfaces with the machine.

AOPDDRs are devices that have a detection zone specified in two dimensions wherein radiation in the near infrared range is emitted by a transmitter element(s).

When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection whereby the presence of the object can be detected.

NOTE 1 Under certain circumstances, limitations of the sensor in relation to its use need to be considered.

For example:

— Objects that generate mirror-like (specular) reflections may not be detected if the diffuse reflectance value is less than that specified for the "black" test piece.

— The determination of the minimal reflection factors for the detection of obstacles is based on the clothing of a person.

Objects having a reflectivity lower than that considered in this Standard may not be detected.

Excluded from this Standard are AOPDDRs employing radiation of wavelength outside the range 820 nm to 946 nm, and those employing radiation other than that generated by the AOPDDR itself.

For sensing devices that employ radiation of wavelengths outside this range, this Standard may be used as a guide.

This Standard is relevant for AOPDDRs having a stated detection capability in the range from 30 mm to 200 mm.

AOPDDRs intended for use as trip device using whole-body detection with normal approach (approach from the frontal direction) to the detection zone and having a stated detection capability not exceeding 200 mm shall meet the requirements of clause A.12.

AOPDDRs intended for a direction of approach normal to the detection zone and having a stated detection capability of approach normal to the detection zone and having a stated detection capability in the range from 30 mm to 70 mm shall meet the requirements of clause A.13.

NOTE 2 According to JIS B 9715, 6.3 foreseeable angles of approach greater than 30° should be considered parallel approach.

NOTE 3 According to JIS B 9715, 6.2 when electro-sensitive protective equipment employing active opto-electronic protective devices is ued for direction of approach parallel to the detection zone the device should have a detection capability in the range from 50 mm to 117 mm.

This Standard may be relevant to applications other than those for the protection of persons, for example, for the protection of machinery or products from mechanical damage.

In those applications, different requirements may be necessary, for example when the materials that have to be recognized by the sensing function have different properties from those of persons and their clothing.

This Standard does not deal with electromagnetic compatibility (EMC) emission requirements.

Opto-electronic devices that perform only one-dimensional spot-like distance measurements, for example, proximity switches, are not covered by this Standard.

NOTE 4 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

IEC 61496-3: 2008 Safety of machinery-Electra-sensitive protective equipment-Part 3: Particular requirements for Active Opto-electronic Protective Devices responsive to Diffuse Reflection (AOPDDR) (lDT)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
