Hey folks,  I have a question I'd like to bounce off you'all.  I've been asked several times over the years about the "two" different ANSI standards for HP Techs - N18.1 and 3.1.  The common belief is that N18.1 requires 2 years of experience and 3.1 requires 3 years.  After researching as much as I can find, I've come to this conclusion and wanted to know if I'm offbase.

ANSI N18.1-1971 Section 4.5.2 Technicians:  Technicians in responsible positions shall have a minimum of two years of working experience in their specialty.  These personnel should have a minimum of one year of related technical training in addition to their experience.

ANSI/ANS 3.1 has gone through several revisions.  The 1978 version was the most restrictive with Section 4.5.2 that stated:  Technicians shall have three years of working experience in their specialty of which one year should be related technical training.  

The 1987 version of 3.1 itemized qualifications as:  High School Diploma, 2 years of Radiation Protection experience of which 1 year is Nuclear Power Plant and 3 months is On-site experience.  

The 1993 version of ANSI/ANS 3.1-1993 Section 4.5.3.2 stated the same as the 1987 requirements.  I gather the '93 revision was reaffirmed in '99.  No changes?

Anyway, my conclusion is that some of us older plants are committed in Tech Specs to N18.1-1971 and newer plants are committed to ANS-3.1-1978.  So newer plants may have the "3 year" requirement even though the newer revisions of the ANSI/ANS standard itself backed off from the experience requirement.  

Does that make sense or am I all wet (again)?   And I'm not going to even try to address how the experience time is determined for supplemental staff.
Thanks, Eric
