ISO 14934-4:2014提供了在火灾试验应用中使用热流计的指南，包括常用热流计的说明和工作原理，以及选择和维护热流计的方法。该指南还可用于测量辐射板和其他用于模拟火灾热流的大型热源的热流。当测量来自辐射源的热通量时，它适用于所有常见的测试目的。 ISO 14934-4:2014还提供了热流计的基本理论和工作原理，以及热流计的选择、使用和维护方法。 虽然它特别针对热流计在火灾试验和火灾研究实验工作中的应用，但它也可以作为锅炉、燃烧过程等其他研究应用的指南。 ISO 14934-4:2014未涵盖测量已知质量和热容固体瞬态温度以推断热通量（段塞式热量计类型）的仪器。

ISO 14934-4:2014 provides guidance on the use of heat flux meters in fire testing applications, including the description and working principles of common heat flux meters and methods for their selection and maintenance. The guidance can also be applied to measuring heat flux from radiant panels and other large heat sources used to simulate the heat flux from a fire. It is applicable for all common testing purposes when measuring heat flux from radiant sources. ISO 14934-4:2014 also provides basic theory and working principles of heat flux meters and methods for selection, use, and maintenance of heat flux meters. Although it is particularly aimed at the application of heat flux meters in fire tests and experimental works of fire research, it can also serve as a guide for other research applications like research of boilers, combustion processes, etc. Instruments, which measure the transient temperature of a solid body of known mass and heat capacity to infer the heat flux (slug calorimeter type), are not covered by ISO 14934-4:2014.
