TB/T 1537-1997 in English

本标准规定了铁道保温车隔热性能的试验评定方法。保温车的隔热性能采用综合传热系数K值来表示。
本标准采用两种试验评定方法：第一种是热稳定法，适用于各种保温车；第二种是非热急定法，用在恒温试验室时，适用于各种保温车；当用在非恒温试验室时、仅适用于定型成批生产产品的抽检和旧车改造后的试验评定。

Scope

This standard specifies the test evaluation method for the thermal insulation performance of railway insulated cars. The thermal insulation performance of the insulated cars is expressed by the comprehensive heat transfer coefficient K value. This standard uses two test evaluation methods: the first is the thermal stability method, which is suitable for dry All kinds of insulated cars; the second is the non-thermal stabilization method. When used in a constant temperature test room, it is suitable for all kinds of insulated cars; when used in a non-constant temperature test room, it is only suitable for sampling of finalized batch production products and old car modifications. subsequent test evaluation.
