IEC 60754-2:20 1+A1:2019规定了通过测量燃烧过程中放出的气体产生的水溶液的酸度（pH）和电导率来确定取自电缆或光纤电缆结构的材料燃烧过程中放出的气体的潜在腐蚀性的设备和程序。本标准中规定的一般方法用于测试电缆结构中使用的单个部件。给出了计算特定电缆中材料组合加权值的公式。使用该方法将能够验证适当电缆规范中规定的电缆结构的单个组件或组合组件的相关要求。包括用于测试单个组件的简化方法，其中仅需要证明符合质量控制目的的规定性能要求。与上一版相比的重大技术变更如下: -改进与气体捕获有关的安全要求的定义； -介绍制备更均匀燃烧的试样的指南； -公差和精度的更好表达； -阐明电导率和酸度函数； -加热过程的改进定义； -用于测定pH值和电导率的测试温度的定义具有更高的精确度； -修正计算测试结果的公式。 根据IEC指南104，它具有水平标准的地位。该合并版本由第二版（2011年）及其修正案1（2019年）组成。因此，除了本出版物之外，没有必要下令进行修订。

IEC 60754-2:2011+A1:2019 specifies the apparatus and procedure for the determination of the potential corrosivity of gases evolved during the combustion of materials taken from electric or optical fibre cable constructions by measuring the acidity (pH) and conductivity of an aqueous solution resulting from the gases evolved during the combustion. The general method specified in this standard is intended for the testing of individual components used in a cable construction. Formulae are given for the calculation of a weighted value for a combination of materials found in a specified cable. The use of this method will enable the verification of relevant requirements for either individual components or combined components of a cable construction stated in the appropriate cable specification. A simplified method is included for the testing of individual components where it is required only to demonstrate compliance with a stated performance requirement for quality control purposes. The significant technical changes with respect to the previous edition are as follows:
- improved definition of safety requirements relating to capture of gases;
- introduction of guidance on the preparation of test specimens for more even combustion;
- better expression of tolerances and precision;
- clarification of the conductivity and acidity functions;
- improved definition of the heating procedure;
- greater precision in the definition of the test temperature for the determination of pH value and conductivity;
- correction of the formulae for the calculation of the test results.
It has the status of a horizontal standard in accordance with IEC Guide 104. This consolidated version consists of the second edition (2011) and its amendment 1 (2019). Therefore, no need to order amendments in addition to this publication.
