Electrical Equipment for Laboratory Use; Part 2: Particular Requirements for Autoclaves Using Steam for the Treatment of Medical Materials and for Laboratory Processes

UL 61010A-2-041

1 Scope and object

This clause of part 1 is applicable except as follows:

1.1 Scope

Replacement:This standard applies to AUTOCLAVES, including those with an automatic loading and unloading system, which incorporate a PRESSURE VESSEL using steam within the absolute pressure range from 0 to 500 kPa, and intended for the treatment of medical materials and for laboratory processes, for example for sterilization.NOTESNational and other regulations or codes apply for the safety of automatic loading and unloading systems.All pressures are specified in absolute terms. Atmospheric pressure (1 bar) - 100 kPa.Where an AUTOCLAVE incorporates a steam generator having its own PRESSURE VESSEL within the same enclosure, the applicable safety requirements for the AUTOCLAVE PRESSURE VESSEL apply also to the steam generator (see 14.105).

1.1.2 Equipment excluded from the scope

Addition:Add the following new dash:

- pressurized environmental cabinets.

NOTESSince all AUTOCLAVES covered by this part 2 use steam, other types using dry heat, toxic gas or radiation are not included.This standard does not deal with special requirements for protection against chemical and high-risk micro-biological hazards associated with the autoclave load, nor with requirements for the design of the PRESSURE VESSEL itself.

1.4 Environmental conditions

Replacements:Replace the first dash by the following new dash:

- Indoor use, and outdoor use for AUTOCLAVES if specified by the manufacturer (see 11.6 of part 1).

Replace the fourth dash by the following new dash:

- maximum relative humidity 85% at any temperature between 5?C and 40?C.
