选择正确的UV-A紫外辐照度计

根据您的无损检测需求选择正确的UV-A紫外辐照度计

瑞典蓝宝长期参与制定标准和无损检测行业方向的委员会的过程中，团体很少有能力将实践和理论要求结合成一个合格的行业标准。有能力的人通常是少数。委员会和标准由分销商、销售经理和制造商组成，他们无意为产品和程序创建更好的框架。紫外照度计和紫外线校准就是一个完美的例子。

令人羞愧的是，无损检测行业在2023年对紫外照度计的校准没有任何合格的要求。许多校准车间几乎没有能力，没有可追溯性，没有经过验证的程序，没有证书，只有以前教过的东西。过去制定的任何合格标准都已被废除，取而代之的是天真的定义，这些定义在技术上毫无意义，但允许销售人员在没有人提出任何问题的情况下继续销售产品和服务。委员会强烈反对将经审计的认证制度化，因为这暴露了紫外照度计制造商和紫外线校准实验室不够好。

作为一级、二级和三级或采购经理，你有责任提出正确的问题。ISO 17025认证是由外部审计师审计的认证，也是证明某人能力的认证。紫外照度计制造商和紫外线校准实验室都应通过ISO 17025认证。如果不能确保紫外照度计测量准确，为什么要花1500美元买紫外照度计，花250美元校准紫外照度计。航空航天组织有不同的紫外线强度要求是有原因的——空客、波音、普拉特和惠特尼、美国空军、劳斯莱斯。如果你不能自信地衡量，你怎么知道自己遵守了他们的程序？

消除灰色地带，使合格认证制度化，并拥有尽可能多的ISO 17025认证公司，以便有能力的年轻人取代老一代，这符合无损检测行业的大利益。是时候改变了！

Select the Correct UV-A Meter for your NDT Needs

During our long experience in participating in committees that shape standards and the direction of the NDT profession, groups are seldom competent enough to combine the practical and the theoretical requirements into a competent industry standard. The competent are typically a minority. Committees and Standards are surrounded by distributors, sales managers, manufacturers that have no intention of going the extra mile to create a better framework for products and procedures. UV meters and UV calibrations are a perfect example.

It is shameful that the NDT profession in the year 2023 does not have any competent requirements for the calibration of UV meters. Many calibration shops have very little capabilities, no traceability, no proven procedures, no certifications, only whatever they were taught from the previous guy. Any competent standards written in the past have been scrapped and replaced by naïve definitions that make no technical sense but allows sales people to continue selling products and services without anyone asking any questions. Committees fiercely resisted institutionalizing audited certifications because that exposes UV meter manufacturers and UV calibration labs that are not good enough.

It is your responsibility as a Level I, II and III or sourcing manager to ask the right questions. ISO 17025 certification is the ONLY certification that is audited by an external auditor and the only certification that is a proof of someone’s competence. All UV meter manufacturers and all UV Calibration labs should be ISO 17025 certified. Why are you then paying $1500 for a UV meter and $250 for a UV meter calibration if not to be sure that the UV meter measures accurately. There is a reason why Aerospace organizations have different UV intensity requirements – AIRBUS, BOEING, PRATT & WHITNEY, USAF, ROLLS-ROYCE. How do you know you are in compliance with their procedures if you cannot measure with confidence?

It is in the best interests of the NDT profession to eliminate grey areas, institutionalize competent certifications and have as many ISO 17025 certified companies as possible so that competent younger people replace the old generation. Time for change!
