Inspection Definitions

Reference to standard practice in the industry would be the best approach. NACE publication 6J-162 Guide to the preparation of contracts and specification for the application of protective coatings, will give her some guidelines to check. Then NACE publication 6D-161 Specification format for surface preparation and material for industrial maintenance painting will give her an idea on how painting should be done. To answer the rest of their questions : NACE publication 6B-157 Protective coating for atmospheric use: Their Surface preparation and application, physical characteristic and resistance.

Inspection requirements: shall consist of primary inspection of the work to be completed as well as the equipment and supplies, Intermediate inspection includes the scrutiny of surface preparation and actual coating work. The final inspection to include the acceptance of appearance, film thickness, continuity and final cure.

Surface preparation shall include a full description of appearance and anchor pattern required for the job as well as other requirement such as abrasive, nozzle pressure, nozzle size, blasting procedure etc..

Hope this will help as a start...

Random Inspection generally includes inspection of base metals, fittings, filler metals, procurement incl. of heat nos. Chemistry, thickness at random, Welding Inspection including visual inspection, few samplings of Radiographic films – its evaluation, heat treatment details if carried out including viewing of thermal charts & coverage of welding in various sub –assembly's, sample of paint coating etc. depending upon the type of job. May be it may vary for your 3 part coating on pipe spools.

It is not a detailed or full 100 % inspection ( done as per Quality Plan) but mostly done at the end and before dispatch of the items to check whether in - process inspection ( by the fabricator themselves or their inspection agencies and mostly covering 100 % ) was done properly or not and carried out by independent Inspection agency on behalf of the Client.

Of course there could be a disparity in above thinking, but this is what we have done for couple of our clients and accepted by them.

Another type of random inspection covers inspection right from the raw material stage to final dispatch but covers only 10 or 20 % (selective at places) of total to be inspected, compared to detailed inspection which is more or less 100 %.

Service Charges for a detailed inspection again are much more than charges for random inspection as no. inspection hours spent are more in detailed inspection.

Now you know your quote and it is up to you to decide.

I'm afraid I would be 'grinmpy Del' and ask why on earth and admin clerk is deciding QA policy on a job?...I'd probably just bypass 'em altogether and talk to the customer and QA manager.... leave adnin clerks to do admin.

Maybe you should spend some time explaining quantum mechanics to the tea lady?

(Don't s'pose anyone has a tea lady anymore? )

Well Cat, I am a Cranky Old Goat out there in the field, and by the way, this is for the company I interviewed with and turned down. More companies over here are giving the admin clerks new titles (inspection coordinators) and as you said, none have a clue. It is a struggle, but I am showing minute bits of progress. PM and PE agree with me and somehow their directive fails when sent to the clerks. I was sorta of looking for a generic ITP suggesting percentages without QA Jargon (Common English) to present to her. I have worked up a schedule and stated why it would take X number of hours. I sent this post through the back-door of the company to get feedback also. I informed Management that if this kind of stuff continues, no more work with them. In fact, I have decided that one of their coordinators requests will be refused.

Getting some good input here, those damn bean counters are trying to kill us, though.

Tell the clerk you'll do a full inspection but report it randomly. Everybody happy ! Ha.
