CAN/ULC-S145全尺寸室角试验标准及目的

CAN/ULC-S145 Standard Method of Test for the Evaluation of Protective Coverings for Foamed Plastic Insulation-Full Scale Room Test
CAN/ULC-S145 泡沫塑料绝缘保护层评定的标准试验方法——全尺寸室内试验

The purpose of this test method is to determine the contribution to fire growth of protective coverings over foamed plastic insulation when tested in a Full-Scale Room Test in accordance with CAN/ULC-9705, Fire Tests - Full-Scale Room Test for Surface Products, except as specified in this Standard.

This test method measures the time to flashover under specified test conditions. Provisions are made to measure smoke obscuration, rate of fire growth and rate of heat release of the protective covering and foamed plastic insulation room lining.

This test method is not intended to determine the fire resistance rating of wall or ceiling assemblies lined with foamed plastic insulation and a protective covering. In addition, this test method does not identify which products of combustion, nor risks associated with products of combustion.

This test method provides for classifications of 10 min and 20 min, which are not equivalent to classifications prescribed in CAN/ULC-S124, Standard Method of Test for the Evaluation of Thermal Barriers for Foamed Plastic.

CAN/ULC-S145全尺寸室角防火试验原理

通过设置地地面中心的热流计测量总热流量，估算房间内火自点火源向其他物体蔓延的可能性。通过测量燃烧的总热释放速率来估算火向房间外物体蔓延的可能性。通过测量某些有毒气体来测定能见度降低的危害。通过拍照及摄像方式来记录火灾增长。
