Performance Requirements7.1 Be ab

16、le to provide a continuous flow of warm airbetween 27 and 35C (80 and 95F) at a flow rate of not lessthan 0.24 m3/s (500 ft3/min).7.2 The input line shall be filtered using an ASTM Number7 filter (manufactured according to Specification E11)toremove solid contaminants that might damage the equipment

17、or injure the personnel in the shelter.NOTE 3The air inlet will provide suction to the area around the inlet.The user may wish to provide a design to prevent covering or clogging theinlet with debris and suitable marking devices to warn users of the inletssuction.Additionally, as specified, the inle

18、t filter is not intended to protectagainst chemical and biological warfare agents. The sole intended purposeof the inlet filter is to protect the air heater device from debris that may beattracted to it as a result of the suction of the inlet.7.3 Be capable of providing warm air flow within thetempe

19、rature range specified in 7.1 within 2 min of beingsupplied 20 to +35C (4 to +95F) feed air.8. Other Requirements8.1 Contain sufficient hoses as part of the unit packaging toallow for an air intake up to 15.24 m (50 ft) distant and providewarm air to a shelter up to 7.62 m (25 ft) from the unit. The

20、warm air outlet duct from the unit shall be able to connect toa 15-cm (6-in.) duct.9. Dimensions, Mass, and Permissible Variations9.1 The unit shall be man-transportable by not more thanfour first responders carrying the assembled unit and not weighmore than 91 kg (200 lb) not including the fuel and

21、 hoses.TEST METHODS10. Scope10.1 These test methods shall be used to insure portable airheaters comply with the requirements of this specification.11.
