If you'll forgive me... **PASSING is not the reason for a lab; testing to a standard is.**
If [insert firm name] management is too cheap to BUILD to that standard, they will soon be too cheap to build at all, and will instead buy everything, trusting in vendors' often unverified promises of compliance. You might still have work. I once worked for a computer company (now deceased) which bought a laptop computer. When we tested samples. they were 20dB over the Class B limit. "Sorry! We accidentally sent unshielded units!" was the response. But everyone figured that if we'd accepted them, they would have insisted they'd met the contract and kept shipping. And billing. Some recipient companies would have kept selling, too. Given a choice of labs, a smart (or ethical) firm should avoid cherry-picking for passing results. Indeed, they might choose one that's harder to pass. Why? Because somewhere, there's a customer or a regulator who has a lab just as hard to pass at. There have been studies on lab uncertainty, and it is VERY unusual to get two labs to agree with a complex EUT.
