成束电缆燃烧测试仪

EN 50399

EN 50399以IEC 60332­3为基础,增加了热释放测量和改进的进气系统。这是通过安装一个小的测量管段到排气管道系统,并使用相关的FTT 气体分析仪和软件来实现的。该测量管段装有所有的气体取样探头、温度和质量流量探头,并有连接烟气测量系统的端口。

The gas analysis instrumentation is housed in a 19″ instrument rack containing:

  • 带温度和压力补偿的氧分析仪(顺磁性),用于主要的热释放测量;
  • 用于热释放测量的二氧化碳分析仪(红外) ;
  • Dual-stage soot filter, refrigerant cold trap, drying column, pump and waste regulators for conditioning the sample gases prior to analysis
  • 烟气测量系统的控制装置(如购买) ;
  • 数据记录仪(如购买)。

Clients already owning the FTT Dual Cone Calorimeter, ISO 9705 Room/Corner test or SBI can use their cone instrumentation to measure the heat release rate from their IEC 60332-3. Alternatively, the EN 50399 Gas Analysis rack can be used to instrument other calorimeters (e.g. FTT Dual Cone Calorimeter etc.).

IEC 60332-3

The European Commission and The European Cable Industry (EUROPACABLE) are finalising Classification criteria for evaluating electric cables throughout Europe under the Construction Products Directive (CPD). The Classification utilises the results obtained from traditional IEC 60332-3 test equipment fitted with heat and smoke release measurement instrumentation. The former is calculated by continuous measurement of the oxygen consumed and carbon dioxide generated in the combustion process. The basis of the new test protocol was developed by FTT’s Andrew Green with colleagues from SP (Sweden), ISSeP (Belgium), CESI (Italy) and Interscience (UK) as part of an EC-funded FIPEC project. This project was managed by FTT director Stephen Grayson.

Modifying Existing IEC 60332-3 Apparatus To Measure Heat Release
Conversion of the existing IEC 60332-3 apparatus to measure heat release is accomplished by fitting a small instrumented section of ducting into the exhaust system of the rig and using this with the associated FTT gas analysis instrumentation and software and a modified test protocol. The duct section houses all gas sampling probes, temperature and mass flow probes needed, and the smoke measuring system.
