Standard Specification for Portable Water Heaters Used at Personnel Decontamination Stations

ABSTRACT
This specification is used to standardize the portable water heaters used on personnel decontamination lines to insure the heaters provide sufficient heated water for as long as they are needed during the emergency. The heater materials of construction shall be easily cleaned of surface mud and grime with no degradation of the unit's ability to perform its function. The performance requirements for portable water heaters are presented in details. The rotometer test method, and ASTM test method shall be performed to meet the requirements prescribed. The water heater unit's water flow shall be measured, and recorded. The water heater unit's cold water inlet and warm water output temperature shall be measured and recorded. The water heater unit's water supply and outlet pressures shall be measured and recorded.
SIGNIFICANCE AND USE
12.1 The use of these acceptance tests will insure that organizations buying portable heaters will be assured the heaters meet certain performance requirements.
SCOPE
1.1 This specification is used to standardize the portable water heaters used on personnel decontamination lines to insure the heaters provide sufficient heated water for as long as they are needed during the emergency.
Note 1: These heaters are not intended to be used for the decontamination for any other surface or material. Also, these heaters are intended to be portable and easy to use by first responders during a chemical, biological, radiological, nuclear, and explosive (CBRNE) event.  
1.2 This specification contains a specification section and a test methods section so users need to refer to the section applicable to their needs when using this standard specification.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
Note 2: The U.S. first responder personnel using the equipment manufactured under this standard are not likely to be familiar with SI units so English units need to be included as part of the system documentation and shown on control panels for any equipment sold to U.S. organizations.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
