ASTM E1474美標熱釋放速率測試

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 用小型耗氧量熱計測定裝飾傢俱和床墊部件或元件的熱釋放速率的標準試驗方法

錐形量熱儀（Cone Calorimeter，簡稱CONE）是火災科學研究領域中最為重要的儀器設備之一。它不僅可以用於研究各類材料或製品的燃燒性能，以評價材料或製品的燃燒行為，而且其測得的資料還是性能化火災設計和火災模型化最為重要的資料來源。此外，通過CONE測試還能在一定程度上預測材料或製品在大尺寸試驗中的燃燒行為和燃燒性能。錐形量熱儀法(CONE)和微型量熱儀法(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等標準熱釋放速率的測試，諮詢電話：+86 25-8658 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.
