Safety of machinery-Positioning of safeguards with respect to the approach speeds of parts of the human body
|Publication Date:||25 May 2013|

This Standard establishes the positioning of safeguards with respect to the approach speeds of parts of the human body.
It specifies parameters based on values for approach speeds of parts of the human body and provides a methodology to determine the minimum distances to a hazard zone from the detection zone or from actuating devices of safeguards.
The values for approach speeds (walking speed and upper limb movement) in this Standard are time tested and proven in practical experience. This Standard gives guidance for typical approaches. Other types of approach, for example running, jumping or falling, are not considered in this Standard.
NOTE 1 Other types of approach can result in approach speeds that are higher or lower than those defined in this Standard. Safeguards considered in this Standard include:
a) electro-sensitive protective equipment (see JIS B 9704 series), including: light curtains and light grids (AOPDs); laser scanners (AOPDDRs) and two-dimensional vision systems;
b) pressure-sensitive protective equipment (see JIS B 9717-1, ISO 13856-2 and ISO 13856-3), especially pressure-sensitive mats;
c) two-hand control devices (see JIS B 9712);
d) interlocking guards without guard locking (see JIS B 9710).
