Bs en 14181校准和测试

Bs en 14181是包含校准的欧洲标准, 测试, 及持续排放监察系统的整体表现. Our team undertake annual EN 14181 maintenance 和 annual surveillance 测试 to ensure safe 和 compliant operations to all quality assurance levels. 

什么是EN 14181?

EN 14181 describes the quality assurance procedures needed to ensure that CEMs - installed to measure emissions to atmosphere – comply with strict requirements related to uncertainty on measured values. There are 4 quality assurance levels defined in EN 14181, which are explained further down the page. 

为什么选择im体育APP进行EN 14181校准和测试?

Our dedicated Emissions Monitoring Teams conduct more 测试 of this kind than anyone else in the UK or 爱尔兰. 每年通过350多个EN 14181项目，我们获得了巨大的价值, 现实世界的, 有处理各种可能出现的情况的实际经验.

Our vast experience in delivering CEMS measurements that are representative 和 accurate, gives you confidence that your CEMS is reliable 和 functioning to a high st和ard in order to comply with legislation. 

如果CEMS工作不准确, 我们的专家将找出问题的来源，并就最佳行动方案向您提供建议. We offer training courses for detailed insight into best practice for the management of CEMS. 此外，我们提供 临时河北 solutions to eliminate the risk of non-compliance after an unexpected breakdown of your system.

QAL1 

QAL1 uses pre-described criteria to prove that the total uncertainty of the CEMS meets the requirements 和 specifications 和 is fit for purpose.

The total uncertainty is calculated by summing together all the relevant uncertainty components arising from specific performance characteristics.

QAL2

QAL2涉及使用EN ISO/IEC 17025认可的测试实验室, 例如im体育APP Materials 技术, ，与营运的中央监测系统一起产生一套可比较的数据结果.

本质量保证程序用于测定igf校准函数, 可变性, 并建立适用于该功能的校准范围.

Note - 可变性 is a test of the measured values of the CEM against the maximum permissible uncertainty given by legislation.

QAL3

质量报告3展示了CEMS持续的质量保证和质量控制. QAL3不同于QAL2和AST，因为它是在常规基础上进行的.g. 每周, fortnightly or monthly) usually by the operator to demonstrate the CEMS are under control 和 continues to function normally.

ast

Annual 系统s Tests (ast) are conducted annually following any QAL2 和 are generally considered a “mini QAL2”. AST determines whether the calibration functions established during the QAL2 remain valid 和 whether the associated range can be extended following a larger spread of data. 虽然类似于QAL2, AST“平行测量”在至少1天内减少到至少5次. 而QAL2则需要在3天内进行至少15次“平行测量”.

EN 14181培训课程

我们在您的网站上提供量身定制的培训课程, 在线或在我们的im体育APP实验室之一. 本课程将带您从头到尾完成EN 14181活动, 围绕计划测试的最佳实践, 与CEMS制造商沟通, 关于成对测量的复杂性, 河北数据, 校准功能和更多.

线性检查

im体育APPs Centre of Technical Excellence teams regularly conduct Linearity checks to assess the linear performance of the CEM in accordance with EN 14181.  This is typically conducted at 2 x the Daily ELV (Emission Limit Value) or the Short Term ELV.   We hold ISO 17025 certified calibration 气体 with an uncertainty of < 2%.   The linearity measurements can sometimes be used as surrogate data to establish calibration functions.  线性检验是通过浓度为零来进行的, 20%, 40%, 60%, 80%的范围, 最后一个零. 我们还确定T90响应时间和所需的各种其他检查.
