Accuracy of Surveyors Tapes

Andrew,

I Googled EEC Class II tapes and found this

Isn't it strange how others question get the rest of us curious to find an answer!

Henry

Look for Directive 73/362/EEC, and possibly some later amendments. It deals with accuracy and markings of measures

It does not relate to what the tapes are made of, but the tapes material may determine what class it falls under.

Henry, well done, how the heck did you find that? I'm amused to see that it cites cms which I understood are now frowned on by Brussels !

AWEM

And everyone else except dressmakers and the BBC...............

I guess it got me curious as it's the standard required for measuring yacht sails. I do that for models but am expected to use the RYA standards.

As ever with Google the results depend on the words you use to search Henry

My first question would be to ask for the calibration records.

In industry, anything that measures must be calibrated and recorded

You certainly get some strange results if you search in Google for '"EEC class II" definition' (with double quotes, without single).

The message from "Andrew Mawson" contains these words:

AIUI the cm is not a preferred unit in SI Metric but the fount of all wisdom on SI Metric is the ISO, not the European Union. So it is quite likely that the EU, like the broken British educational system, have decided to ignore the bits of the standard they don't like (or don't understand).
