根據(jù)您的無損檢測需求選購正確的UV-A紫外照度計(jì)
在瑞典蘭寶參與制定標(biāo)準(zhǔn)和無損檢測專業(yè)方向的委員會(huì)的長期經(jīng)驗(yàn)中，團(tuán)隊(duì)很少有能力將實(shí)踐和理論要求結(jié)合成一個(gè)合格的行業(yè)標(biāo)準(zhǔn)。有能力的人通常是少數(shù)。委員會(huì)和標(biāo)準(zhǔn)被分銷商、銷售經(jīng)理、制造商包圍，他們無意加倍努力為產(chǎn)品和程序創(chuàng)建更好的框架。紫外照度計(jì)和紫外線校準(zhǔn)就是一個(gè)很好的例子。
令人慚愧的是，2023年的無損檢測專業(yè)對紫外照度計(jì)的校準(zhǔn)沒有任何勝任的要求。許多校準(zhǔn)車間的能力很少，沒有可追溯性，沒有經(jīng)過驗(yàn)證的程序，沒有認(rèn)證，只有他們從前一個(gè)家伙那里學(xué)到的東西。過去編寫的任何合格標(biāo)準(zhǔn)都被廢棄了，取而代之的是幼稚的定義，這些定義沒有技術(shù)意義，但允許銷售人員繼續(xù)銷售產(chǎn)品和服務(wù)，而無需任何人提出任何問題。委員會(huì)強(qiáng)烈反對將經(jīng)審計(jì)的認(rèn)證制度化，因?yàn)檫@暴露了紫外照度計(jì)制造商和紫外線校準(zhǔn)實(shí)驗(yàn)室不夠好的情況。
作為一級(jí)、二級(jí)和三級(jí)或采購經(jīng)理，您有責(zé)任提出正確的問題。ISO 17025認(rèn)證是由外部審計(jì)師審核的認(rèn)證，也是證明某人能力的認(rèn)證。紫外線測量儀制造商和紫外線校準(zhǔn)實(shí)驗(yàn)室都應(yīng)通過ISO 17025認(rèn)證。如果不確保紫外照度計(jì)測量準(zhǔn)確，為什么要為紫外照度計(jì)支付 1500 美元，為紫外照度計(jì)校準(zhǔn)支付 250 美元。航空航天組織有不同的紫外線強(qiáng)度要求是有原因的 - 空中客車，波音，普惠，美國空軍，勞斯萊斯。如果您不能自信地衡量，您如何知道您遵守了他們的程序？
消除灰色地帶，將合格的認(rèn)證制度化，并擁有盡可能多的ISO 17025認(rèn)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(yè)的大利益。是時(shí)候改變！
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!
