選擇正確的UV-A紫外輻照度計(jì)

根據(jù)您的無損檢測(cè)需求選擇正確的UV-A紫外輻照度計(jì)

瑞典藍(lán)寶長(zhǎng)期參與制定標(biāo)準(zhǔn)和無損檢測(cè)行業(yè)方向的委員會(huì)的過程中，團(tuán)體很少有能力將實(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)由分銷商、銷售經(jīng)理和制造商組成，他們無意為產(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)完美的例子。

令人羞愧的是，無損檢測(cè)行業(yè)在2023年對(duì)紫外照度計(jì)的校準(zhǔn)沒有任何合格的要求。許多校準(zhǔn)車間幾乎沒有能力，沒有可追溯性，沒有經(jīng)過驗(yàn)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(biāo)準(zhǔn)都已被廢除，取而代之的是天真的定義，這些定義在技術(shù)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(xù)銷售產(chǎn)品和服務(wù)。委員會(huì)強(qiáng)烈反對(duì)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。

作為一級(jí)、二級(jí)和三級(jí)或采購(gòu)經(jīng)理，你有責(zé)任提出正確的問題。ISO 17025認(rèn)證是由外部審計(jì)師審計(jì)的認(rèn)證，也是證明某人能力的認(rèn)證。紫外照度計(jì)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。如果不能確保紫外照度計(jì)測(cè)量準(zhǔn)確，為什么要花1500美元買紫外照度計(jì)，花250美元校準(zhǔn)紫外照度計(jì)。航空航天組織有不同的紫外線強(qiáng)度要求是有原因的——空客、波音、普拉特和惠特尼、美國(guó)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(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(cè)行業(yè)的大利益。是時(shí)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!
