该技术规范补充了EN ISO/IEC 17025:2005的要求，适用于对定期测量固定源排放的实验室的能力进行演示，包括 - 采用有代表性的排放样品和随后的气体和颗粒物种实验室分析， - 确定参考量如温度，压力，水汽和氧气含量的现场和 - 在现场使用便携式仪器（如手持式仪器和移动实验室使用的可移动仪器）。 该技术规范适用于所有实施定期测量固定源排放的实验室，按照EN 14181:2004标准安装的自动化测量系统和/或用于合格评定目的的自动化测量系统的现场测试

This Technical Specification supplements the requirements of EN ISO/IEC 17025:2005, and is suitable for the demonstration of competence of laboratories that undertake periodic measurement of emissions from stationary sources including - the taking of representative samples of emissions and subsequent laboratory analysis for gases and for particulate species, - the determination of reference quantities such as temperature, pressure, water vapour and oxygen content in the field and - the use of portable instruments (such as hand held instruments and transportable instruments used in mobile laboratories) in the field. This Technical Specification is applicable to all laboratories undertaking the periodic measurement of emissions from stationary sources, the calibration of installed automated measuring systems in accordance with EN 14181:2004 and/or the field testing of automated measuring systems for conformity assessment purposes.
