JIS B9704-2-2008《机械安全–电感保护设备–第2部分:一般要求和试验》

(Replacement. This clause of Part 1 is replaced by the following:t
This Standard specifies requirements for the design, construction and testing of
ESPE designed specifically to detect persons as part of a safbty-related system, em-
ploying AOPDs for the sensing function. Special attention is directed to features which
ensure that an appropriate safety-related performance is achieved. An ESPE may
include optional safety-related functions, the requirements for which are given in
Annex A. 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 func-
tioning of the ESPE and how it interfaces with the machine.
Excluded from this Standard are AOPDs employing radiation at wavelengths out-
side the range 400 nm to I 500 nm.
This Standard may be relevant to applications other than those for t
