根據您的無損檢測需求選擇正確的UV-A紫外輻照度計

瑞典藍寶長期參與制定標準和無損檢測行業方向的委員會的過程中，團體很少有能力將實踐和理論要求結合成一個合格的行業標準。有能力的人通常是少數。委員會和標準由分銷商、銷售經理和制造商組成，他們無意為產品和程序創建更好的框架。紫外照度計和紫外線校準就是一個完美的例子。

令人羞愧的是，無損檢測行業在2023年對紫外照度計的校準沒有任何合格的要求。許多校準車間幾乎沒有能力，沒有可追溯性，沒有經過驗證的程序，沒有證書，只有以前教過的東西。過去制定的任何合格標準都已被廢除，取而代之的是天真的定義，這些定義在技術上毫無意義，但允許銷售人員在沒有人提出任何問題的情況下繼續銷售產品和服務。委員會強烈反對將經審計的認證制度化，因為這暴露了紫外照度計制造商和紫外線校準實驗室不夠好。

作為一級、二級和三級或采購經理，你有責任提出正確的問題。ISO 17025認證是由外部審計師審計的認證，也是證明某人能力的認證。紫外照度計制造商和紫外線校準實驗室都應通過ISO 17025認證。如果不能確保紫外照度計測量準確，為什么要花1500美元買紫外照度計，花250美元校準紫外照度計。航空航天組織有不同的紫外線強度要求是有原因的——空客、波音、普拉特和惠特尼、美國空軍、勞斯萊斯。如果你不能自信地衡量，你怎么知道自己遵守了他們的程序？

消除灰色地帶，使合格認證制度化，并擁有盡可能多的ISO 17025認證公司，以便有能力的年輕人取代老一代，這符合無損檢測行業的大利益。是時候改變了！

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 na?ve 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!
