ASTM E1474美标热释放速率测试

ASTM E1474 Standard Test Method for Determining the Heat Release Rate of Upholstered Furniture and Mattress Components or Composites Using a Bench Scale Oxygen Consumption Calorimeter
ASTM E1474 用小型耗氧量热计测定装饰家具和床垫部件或组件的热释放速率的标准试验方法

锥形量热仪（Cone Calorimeter，简称CONE）是火灾科学研究领域中最为重要的仪器设备之一。它不仅可以用于研究各类材料或制品的燃烧性能，以评价材料或制品的燃烧行为，而且其测得的数据还是性能化火灾设计和火灾模型化最为重要的数据来源。此外，通过CONE测试还能在一定程度上预测材料或制品在大尺寸试验中的燃烧行为和燃烧性能。锥形量热仪法(CONE)和微型量热仪法(MCC)，南京睿督公司提供ISO 5660, ASTM E1354, ASTM E1474, ASTM E1740, ASTM F1550, ASTM D6113, NFPA 264,CAN ULC 135 和 BS 476-15等标准热释放速率的测试，咨询电话：025-8658 3475。

1. Scope

1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter.

1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heating fluxes. The specimen is oriented horizontally, and a spark ignition source is used.

1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354.

1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included.

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.

1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
