Bs en 14181 校准 和 测试

Bs en 14181 is a 欧洲an st和ard that encompasses the calibration, 测试, 和 overall performance of Continuous Emissions Monitoring 系统s (CEMS). 我们的团队每年进行EN 14181维护和年度监控测试，以确保所有质量保证水平的安全和合规操作. 

什么是EN 14181?

EN 14181描述了确保CEMs(用于测量大气排放)符合与测量值不确定度相关的严格要求所需的质量保证程序. 在EN 14181中定义了4个质量保证级别，详见下文. 

Why choose im体育APP for EN 14181 calibration 和 测试?

我们专门的排放监测小组进行的此类测试比英国或爱尔兰的任何其他公司都多. With over 350 EN 14181 campaigns each year we have gained a massive amount of valuable, 现实世界的, practical experience able to deal with every scenario that may arise.

Our vast experience in delivering CEMS measurements that are representative 和 accurate, 使您确信您的CEMS是可靠的，并以高标准运行，以符合法规. 

If a CEMS isn't performing accurately, our experts will source the issue 和 advise you on the best course of action. 我们提供培训课程，详细了解CEMS管理的最佳实践. Additionally, we offer 临时河北 在系统意外崩溃后消除不合规风险的解决方案.

QAL1 

QAL1使用预先描述的准则来证明CEMS的总不确定度符合要求和规范，并适合用途.

总不确定度是通过将由特定性能特征引起的所有相关不确定度分量相加来计算的.

QAL2

QAL2 involves the use of EN ISO/IEC 17025 accredited 测试 laboratories, such as im体育APP Materials 技术, to produce a set of comparable data results alongside the operating CEMs.

This quality assurance procedure is used for the determination igf calibration functions, 可变性, 和 establishing calibration ranges applicable to the function.

注:变异性是指在法例规定的最大容许不确定度下，对电能测量值所作的测试.

QAL3

QAL3 demonstrates ongoing Quality Assurance 和 Quality Control of the CEMS. QAL3 is different from QAL2 和 AST as it is conducted on a routine basis (e.g. 每周, 每两周或每月一次)，通常由操作人员进行，以证明CEMS已受到控制，并继续正常运作.

ast

年度系统测试(ast)每年在任何QAL2之后进行，通常被认为是“迷你QAL2”。. AST决定在QAL2期间建立的校准函数是否仍然有效，以及相关范围是否可以在更大的数据传播后扩展. Although similar to QAL2, AST ‘parallel measurements’ are reduced to a minimum of 5 over a minimum of 1 day. Whereas QAL2 requires a minimum of 15 ‘parallel measurements’ spread across 3 days.

EN 14181 Training Courses

We deliver tailored Training Courses either on your site, online or at one of our im体育APP Laboratories. The course takes you through an EN 14181 campaign from start to finish, best practices around planning the 测试, communications with CEMS manufacturers, the intricacies around the paired measurements, 河北数据, calibration functions 和 much more.

线性检查

im体育APPs技术卓越中心团队定期进行线性检查，以根据EN 14181评估CEM的线性性能.  这通常以每日排放限值的2倍或短期排放限值进行.   We hold ISO 17025 certified calibration 气体 with an uncertainty of < 2%.   线性度测量值有时可以用作建立校准函数的替代数据.  The 线性检查 are conducted by passing concentrations at zero, 20%, 40%, 60%, 80%的范围, 和 a final zero again. We also determine the T90 response time 和 various other checks required.
