The Xtreme Heater has been tested for the ignition protection requirements of the ABYC, the USCG,ISO 8846 and SAE J1171 to determine compliance of the item to the Ignition Protection requirements for electrical components as stated in the ISO Standard ISO 8846 as well as the Electrical System Standard, Title 33 CFR, Part 183, Subpart I, Section 183.410, SAE J1171and the ABYC Certification Handbook.

PROCEDURE

The procedures used to accomplish the Ignition Protection tests are ISO 8846, SAE J1171,and the USCG recommended procedures entitled “USCG Electrical System Standard Test Procedure”, dated January 1978. These procedures are acceptable to the European Community and the United States Coast Guard respectively for establishing conformance to the ignition protection requirements. The Xtreme Heater 600 was chosen for the test as the highest energy producing unit within the family.Upon receipt, the test specimen was inspected for damage and any obvious signs of noncompliance with the requirements of the ISO Standard, the SAE Standard and the USCG requirements. 

REPORT NO. 17230-1

The heater was subjected to an Explosive Atmosphere Exposure Test and a HighTemperature Operating Test. The tested unit, because it only operates normally at between 40°F an 52°F was “tricked” into operating at the required 60°C ambient temperature by removing the system thermostat and placing the thermostat into a cold water bath during testing. Although the thermostat (Airpax 054052A) is a sealed component it was subjected to the Induced Ignition Test as it was the only spark producing component in the assembly.

RESULTS

The results of the test performed indicate that the heater meets the Ignition Protection Test requirements of the USCG, stated in Title 33 CFR 183.410. The test article was operated (50 on-off-on cycles) while in an explosive atmosphere without igniting the atmosphere. At no time during the High Temperature Operating Test was a temperature in excess of the limits of the Standard detected on any exterior surface of the test article or its components. The thermostat contained the energy generated by the 50 Induced Explosions without causing the surrounding explosive atmosphere to ignite.
