This standard establishes ergonomics data and their use in establishing temperature limit values for hot surfaces and in the assessment of the risks of burning.
This standard is applicable within the field of application of the EN 292 to hot surfaces of machinery that are or can be touched during normal use.
This standard provides data concerning circumstances under which contact between bare skin and hot surface does or may lead to burns.
These data allow the assessment of risks of burning.
This standard also provides data to be used to establish temperature limit values for hot surfaces to protect against skin burns. These data can be
used in the development of standards for specific machinery where as a result of a risk assessment temperature limits are required.
The data of this standard are applicable to surfaces of objects with relatively high thermal capacity compared with that of the skin of the human body.
This standard is not applicable if a large area of the skin (approximately 10 % or more of the skin of the whole body) can be in contact with the hot surface.
This standard is also not applicable to skin contact of more than 10 % of the head or contact which could result in burns of vital areas of the face.
NOTE 1 In some cases the results of contact with a hot surface may be more serious for the individual, for example:
a) burns resulting in the restriction of airways;
b) a large burn (more than 10 % of the body surface) may impair the circulation by fluid loss;
c) heating of a large proportion of the head or whole body may lead to unacceptable heat strain even in the absence of burning.
This standard is applicable to the healthy skin of adults.
This standard does not provide data for protection against pain.
NOTE 2 If the burn thresholds specified in this standard are not exceeded, there is normally no risk of burning, when the skin comes in contact with the hot surface, but pain may occur nevertheless. If there is also a need for protection against pain, surface temperature values should be taken from suitable other sources (see annex A).
