ISO 1:2016定义了参考温度和标准参考温度的概念，并指定了对象的几何和尺寸属性规范的标准参考温度值。几何和尺寸属性的一些示例包括工件的尺寸，位置，取向（包括角度），形状和表面纹理。 ISO 1:2016标准也适用于用于验证或校准的被测量的定义

ISO 1:2016 defines the concepts of a reference temperature and of the standard reference temperature, and specifies the standard reference temperature value for the specification of geometrical and dimensional properties of an object. Some examples of geometrical and dimensional properties include size, location, orientation (including angle), form and surface texture of a workpiece. ISO 1:2016 Standard is also applicable to the definition of the measurand used in verification or calibration.
