Historical Version s – view previous versions of standard. C10055, surface temperatures of insulated equipment and appliances may still be high enough to cause burns from contact exposure under certain conditions.

Current practice for this determination is widely varied. The intent of this guide is to tie together the existing practices into a consensus standard based upon scientific understanding of the thermal physics involved.

ASTM-C, –

Flexibility is retained within this guide for the designer, regulator, or consumer to establish specific burn hazard criteria. Most generally, the regulated criterion will be c11055 length of time of contact exposure. 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.

Unusual conditions of exposure, physical health variations, or nonstandard ambients all serve to modify the results. 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. The human burn hazard is defined, and methods are presented for use in the design or evaluation of heated systems to prevent serious injury from contact with the exposed surfaces. For consumer products, a longer s contact time has been proposed by Wu 1 2 and others to reflect the slower reaction times for children, the elderly, or the infirm.

This type of injury is reversible and causes no permanent tissue damage.

ASTM C1055 – 03(2014)

For cases where more severe conditions are mandated by space, economic, exposure probability, or other outside considerationsthis guide may be used to establish a second, less desirable injury level second degree burnswhere some permanent tissue damage can be permitted.

Adtm no time, however, are conditions that produce third degree burns recommended.

The guidelines contained herein are not applicable to chemical, electrical, or other similar hazards that provide a heat generation source at the location of contact. No other units of measurement aetm included in this standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to its use.
