IEC 61298-3:2008规定了对过程测量和控制装置的功能和性能特征进行试验和报告的一般方法和程序。这些测试适用于任何此类设备，其特点是其自身的特定输入和输出变量，以及输入和输出之间的特定关系（传递函数），包括模拟和数字设备。对于需要特殊测试的设备，应使用本标准，以及规定特殊测试的任何产品特定标准。它涵盖了影响量影响的测试。

IEC 61298-3:2008 specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process measurement and control devices. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include analogue and digital devices. For devices that require special tests, this standard should be used, together with any product-specific standard specifying special tests. It covers tests for the effects of influence quantities.
