The fire tests are to be conducted inside a well-ventilated
fire test hall, in order to minimize enclosure effects affecting the
outcome of the testing. The enclosure effects include accumulation
of heat, smoke and water droplets within the test area.
The fire test hall should have an ambient temperature of 20
± 5°C at the start of each test. Standing water should
not be permitted on the floor of the test hall at the start of each
test. The suspended ceiling should be dry at the start of each test.
Details of the fire test hall geometry, the ventilation conditions
as well as of the environmental conditions with respect to the above
should be given in the fire test report.
