This standard, identical to ISO 13916:1996, specifies measurement requirements for preheating temperature, interpass temperature, and preheat maintenance temperature in fusion welding. It defines the location of measurement points (4 times plate thickness from groove edge, max 50 mm), measurement timing (interpass temperature measured instantaneously before arc passage), and types of temperature measuring equipment (thermal sensitive materials, contact thermometers, thermocouples, non-contact devices). It applies to temperature control in welding procedure specifications and excludes post-weld heat treatment temperature measurement.
本标准等同采用ISO 13916:1996，规定了熔化焊预热温度、道间温度及预热维持温度的测量要求。标准明确了测温点的位置（距坡口边缘4倍板厚且不超过50mm）、测量时间（道间温度在电弧经过前瞬时测量）以及测温设备类型（热敏材料、接触式测温仪、热电偶、非接触式装置）。适用于焊接工艺规程中的温度控制，不包括焊后热处理温度测量。

本标准规定了熔化焊预热温度、道间温度及预热维持温度的测量要求其他焊接方法也可参照采用本标准。
温度一般在正对着焊工的工件表面，距坡口边缘4倍板厚，且不超过50 mm的距离处测量。
当工件厚度超过50 mm时，要求的测温点应位于至少75 mm距离的母材或坡口任何方向上的相应位置。
道间温度应在电弧经过之前的焊接区域内瞬时测得。
用于温度测量的设备应在焊接工艺规程中明确，如:热敏材料，如:蜡笔或油漆(TS);接触式测温仪(CT);热电偶(TE);非接触式光学或电子测温装置(TB)。
This standard specifies the measurement requirements for preheating temperature, interpass temperature and preheat maintenance temperature in fusion welding. Other welding methods may also refer to this standard.
The temperature is generally measured on the workpiece surface facing the welder, at a distance of 4 times the plate thickness from the edge of the groove, and not exceeding 50 mm.
When the workpiece thickness exceeds 50 mm, the required temperature measurement point shall be located at a distance of at least 75 mm from the base metal or corresponding position in any direction of the groove.
The interpass temperature shall be measured instantaneously in the welding area before the arc passes.
The equipment used for temperature measurement shall be specified in the welding procedure specification, such as: thermal sensitive materials, e.g. crayons or paints (TS); contact thermometers (CT); thermocouples (TE); non-contact optical or electronic temperature measuring devices (TB).
