Not flame, but comment. Be all that as it may, the fact remains that a reg can pass the CEN tests with a performance about half that of what it takes to pass the US Navy tests (as WOB of 3 j/l compared to 1.4) - the CEN is a pretty wissy test when it comes to extreme performance. I think the only reason companies make a big deal about passing the CEN test is they figure, why not - they payed a lot of money for it, and the customer has no idea what it means anyhow. According to what I've read, the CEN is more concerned with material standards than how the thing works - exactly the sort of governmental busybodiness that seems very common in the more authoratarian European nations, and seems to be spreading with the EEC or whatever they call it now. Also, since the CEN tests are very expensive, and a design cannot be changed without retesting, incremental improvement and debugging are discouraged. I'm still curious about the positive pressure aspect - the CEN tests do not allow it, and most good regs here use it. How do they make it through the CEN test? -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. Send subscribe/unsubscribe requests to `techdiver-request@aquanaut.com'.
