Interpretation in NAS-410 re Cert Expiration

I am trying to implement NAS410, Revision 2. One of the many interesting new features of this document is the interpretation of qualification expiration - that a certification is considered to expire at the end of the month corresponding to the beginning of the certification period. For example, if an individual was certified as a Level II on April 8, 2000, then the expiration would be April 30, 2003 (using a 3-yr period).
Has anyone been using this interpretation before NAS-410 Revision 2 arrived? If so, what industry are you working in, and what have your Customers said? This small allowance has some benefits, I think, and the resulting imprecision of the expiration period is not going to have any real bearing on the actual abilities of the inspector. Your feedback is appreciated!

Hi David,
I believe you must be now working to NAS410 Rev. 3 as the issue has been released March last year.
I personally believe your interpretation is correct, and if I'm not mistaken the same approach implemented by ASNT to their certificates (validity period by month). However, to be on the safe side, I would stick to the date-to-date/ day basis.
The standard is the outline of the minimum requirement. We're okay to exceed the minimum requirement in that circumstance.

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
