Ansi Ncsl Z540.3
From 1994 to 2000, U.S. National standards for calibration laboratory accreditation were set out in the American National Standards Institute standard, ANSI/NCSL Z540-1-1994, “Calibration Laboratories and Measuring and Testing Equipment – General Requirements.' These standards have been updated twice since 2000. The current standard is ANSI/NCSL Z540-3-2006. In common usage, this standard is often shortened to ANSI Z540 or NCSL Z540. ANSI developed ANSI Z540 in collaboration with NCSL, the National Conference of Standards Laboratories.
Parts 2 and 3 are policy and procedure information specific to WMD operations and. Recognition process; Figure 1 is a flow chart showing the Recognition process. Parts 4 and 5 substantially contain ISO/IEC (previously these sections referenced ANSI/NCSL Z540-1-1994 (parts I and II) with NVLAP additions,. ANSI/ NCSL Z540.3-2006 (R2013) - efile This National Standard establishs the technical requirements for the calibration of measuring and test equipment. This is done through the use of a system of functional components.
I just read the Z540.3, as I was unaware the standard was changed from 540.1, twice, sheesh, anyway, from what I can see one of the major changes is the Before and After data. 540.3 says it must appear on the cert, 540.1 does not have that. We offer calibrations but have always had customers request B/A data as it takes longer to do.
Should we have always been doing B/A data? The labs we get our meters done at have separate pricing for B/A data and have z540.1 and 17025 compliance statements. I've re-read the 540.1 standard and it does not require the B/A data. I also don't see the requirement in 17025.
I've been doing this job for a few years, but it never ceases to amaze me how far behind I get in my reading. Thank you in advance, Robbin.
'I'd like to ask this question a bit differently. If ANSI Z540.1 was 'withdrawn' and replaced by Z540.3, and refers to ISO 17025 in matters of calibration of measuring and test equipment (§5.3), but ISO 17025 never refers to Z540, why do we even need Z540? If i'm going to claim compliance, why not just claim ISO 17025 and be done with it?' Yerbero, this is what I have been getting at as well. Does everyone keep forgetting that ANSI Z540.3-2006 is completely VOLUNTARY? The bottomline for our company Yerbero, is the president wants to be able to say the words 'Our company is A2LA Accredited' or 'Our company is ISO 17025 Certified'. The top management perspective is: what ever we need todo to get there is all I care about.
I want to do the minimal amount so that I can make one or both of these statements. As you implement ISO, I recommend to keep a simple goal like this in mind.
Then you will know exactly what you need to do. If you are on a tight schedule (who isn't?) to get ISO 17025 Certified, then you do not need to implement or follow any ANSI Z540.3-2006 guidelines. I hope this helps, and I look forward to any comments. In fact, the Z540.3 books uses the word 'ISO 17025' 3 times. Thanks, Drew G.
