1.1本试验方法描述了使用传感器（其传感元件）测量辐射或对流热通量或两者 (1, 2) 是一种薄的圆形金属箔。虽然辐射环境存在基准校准标准，但对于对流环境，从业人员或政府实体之间没有统一的协议。 1.2以国际单位制表示的数值应视为标准。括号中的数值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This test method describes the measurement of radiative or convective heat flux, or both, using a transducer whose sensing element (1, 2) is a thin circular metal foil. While benchmark calibration standards exist for radiative environments, no uniform agreement among practitioners or government entities exists for convective environments. 1.2 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are provided for information only. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
