适用于以下电气和电子设备的性能规范，主要参考工业应用: -测量电气量的指示和记录仪表； -提供电气量的材料测量； -使用电气方式测量非电量的仪器，用于测量链中所有呈现电气输出信号的部分。 它基于GUM中阐述的用于表示和评估测量不确定度的方法，是指GUM中用于确定用于表示不确定度的间隔的统计程序（包括解释可追溯性链中不可忽略的不确定度的方法）。 目的是提供确保规范一致性的方法，并确定其范围内设备的不确定性。 所有其他必要要求已保留给与本标准范围内特定类型设备相关的独立IEC产品标准。

Applies to the specification of performance, with primary reference to industrial applications, of the following kinds of electrical and electronic equipment: - indicating and recording instruments which measure electrical quantities; - material measures which supply electrical quantities; - instruments which measure non-electrical quantities using electrical means, for all parts of the measuring chain which present electrical output signals. It is based on the methods expounded in GUM for expressing and evaluating the uncertainty of measurement, and refers to GUM for the statistical procedures to be used in determining the intervals assigned to represent uncertainty (including the way to account for non-negligible uncertainties in the traceability chain). The object is to provide methods for ensuring uniformity in the specification and determination of uncertainties of equipment within its scope. All other necessary requirements have been reserved for dependent IEC product standards pertaining to particular types of equipment which fall within the scope of this standard.
