The density is meassured at 25 degrees centigrade by a pyknometric method after degassing under vacuum. Calcined coke may be treated with different types of oil in order to avoid the formation of dust during loading and transportation. The present method does not provide for this elemination of traces of oil which may be present in the sample.
Covers all elements, made of any material, with vertically hinged door leaves in the normal operating condition for which they are designed and installed. The test may be carried out on doorsets installed in a finished building or in a laboratory test rig. The horizontal force required for closing is used as a parameter for quanifying the operating performance. For terms and definitions see 1804…
