Hi Cortland,
and anyone else who gets in this position. First, an assessor cannot stop you using anything. The role of an assessor is eyes and ears in a lab, not a prefect. If an assessor thinks you are doing something wrong, or not complying, then he/she MUST write a deficiency. To do so, they must show you where you are not complying. Force the assessor to do this, do not trust hearsay something is wrong. The reason I say this is because when the report goes back to the assessing body, a different set of eyes reviews the concern. This is where you make your case and can quite often get satisfaction if the deficiency is vague. Second, there is nothing wrong with developing your own generator, I have done it, and will continue to do so, many labs I visit will do too. Assessing labs require you to demonstrate national standards traceability, and give several options to do so. The simplest is going to an accredited cal lab with that type of equipment on their scope. But the path is open for you to do this yourself, IF you put the appropriate measures in place: often times this isn't worth it, so then you fall back to going to an accredited lab. The problem that arises is that most folks do not differentiate properly between a quick check the equipment is functioning Vs a complete review of the entire equipment. Both have their place. Cheers, Derek. -----Original Message----- From: CR <[email protected]> To: EMC-PSTC <[email protected]> Sent: Mon, Mar 3, 2014 2:35 pm Subject: Re: [PSES] Schaffer surge generator I once spent some time at a Southern California lab that built their own damped sinewave circuit only to have an assessor forbid its use because it couldn't be calibrated.
