1、Designation: E 2542 08Standard Specification forPortable Water Heaters Used at Personnel DecontaminationStations1This standard is issued under the fixed designation E 2542; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification is used to standardize the portablewater heaters used on personnel decontamination lines toinsur
3、e the heaters provide sufficient heated water for as long asthey are needed during the emergency.NOTE 1These heaters are not intended to be used for the decontami-nation for any other surface or material. Also, these heaters are intendedto be portable and easy to use by first responders during a che
4、mical,biological, radiological, nuclear, and explosive (CBRNE) event.1.2 This specification contains a specification section and atest methods section so users need to refer to the sectionapplicable to their needs when using this standard specifica-tion.1.3 The values stated in SI units are to be re
5、garded as thestandard. The values given in parentheses are for informationonly.NOTE 2The U.S. first responder personnel using the equipmentmanufactured under this standard are not likely to be familiar with SI unitsso English units need to be included as part of the system documentationand shown on

Mechanical Properties7.1 The heat
16、er materials of construction shall be easilycleaned of surface mud and grime with no degradation of theunits ability to perform its function.7.2 The preferred fuels for the heater section of the portablewater heater are diesel fuel, gasoline, or bottled propane gas. Ifelectricity is used, the circui
17、t shall be no more than 120 V, 30A, single phase, and shall conform to NFPA 70 for outdoorusage.8. Performance Requirements8.1 Using the input flows shown in Table 1, a continuousflow (25 to 60 L/min 6.6 to 15.9 gal/min) of warm water(between 13 and 27C 55 and 80F) is provided at a pressurebetween 2
18、75 and 620 kPa (40 and 90 lb/in.2) at each of theinput conditions.8.2 Be capable of providing a warm water flow within thetemperature range specified in 8.1 within 2 min of beingsupplied 2C (36F) feed water.8.2.1 Use 4-cm (1.5-in.) National Pipe Thread connectors(preferably female) to receive the in
19、put water and discharge theoutlet water. The input lines shall be filtered using anASTM 18sieve. The sieve shall be certified under Specification E11toremove solid debris particles that might damage the equipmentor injure the personnel undergoing the decontaminationshower.NOTE 3As specified, the inl
20、et filter is not intended to protect againstchemical and biological warfare agents. The sole intended purpose of theinlet filter is to protect the water heater device from debris that may beattracted to it because of the suction of the inlet.9. Other Requirements9.1 Contain sufficient hoses as part
21、of the unit packaging toconnect to a water source up to 15.24 m (50 ft) distant andprovide warm water to a shower up to 7.62 m (25 ft) from theunit.10. Dimensions, Mass, and Permissible Variations10.1 The unit shall be man-transportable by not more thanfour first responders carrying the assembled un
22、it and not weighmore than 91 kg (200 lb) not including the fuel and hoses.TEST METHODS11. Scope11.1 These test methods shall be used to insure portablewater heaters comply with the requirements of this specifica-tion.12. Significance and Use12.1 The use of these acceptance tests will insure thatorga
23、nizations buying portable heaters will be assured theheaters meet certain performance requirements.13. Hazards13.1 Personnel using this portable water heater should takeprecautions against normal industrial hazards, such as fire andtemperature hazards or accumulation of exhaust. They shallalso compl
24、y with all other manufacturers warnings whenusing the equipment.14. Procedure14.1 Measurement of the Water Heater Units Water FlowThe water heater units water flow shall be measured, andrecorded, using one of the methods specified in the following:14.1.1 Rotameter Test Method:14.1.1.1 The testing fa
