If you like to setup a quick demo, let us know at support madcad. Most heated apparatus in industrial, commercial, and residential service are insulated, unless thermal insulation would interfere with their function; for example, it is inappropriate to insulate the bottom surface of a flatiron.
However, surface temperatures of insulated equipment and appliances may still be high enough to cause burns from contact exposure under certain conditions.
This guide has been developed to standardize the determination of acceptable surface operating conditions for heated systems. Current practice for this determination is widely qstm. The intent of this guide is to tie together the existing practices into a consensus standard based upon scientific understanding of c105 thermal physics involved.
Flexibility is c0155 within this guide for the designer, regulator, or consumer to establish specific burn hazard criteria.
Most generally, the regulated criterion will be the length of time of contact exposure. It is beyond the scope of this guide to establish appropriate contact times and acceptable levels of injury for particular situations, or determine what surface temperature is safe. Clearly, quite different criteria may be justified for cases as diverse as those involving infants and domestic appliances, and experienced adults and industrial equipment. In the first case, no more than first degree burns in 60 s might be desirable.
In the second case, second degree burns in 5 s might be acceptable. This guide is meant to serve only as an estimation of the exposure to which an average individual might be subjected.
Unusual conditions of exposure, physical health variations, or nonstandard ambients all serve to modify the results. This guide is limited to contact exposure to heated surfaces only.
It should be noted that conditions of personal exposure to periods of high ambient temperature or high radiant fluxes may cause human injury with no direct contact. This guide is not intended to cover hazards for cold temperature exposure, that is, refrigeration or cryogenic applications. The procedure found in this guide has been described in the literature aatm applicable to all heated surfaces.
