It's easy to find cheesecloth, but finding the right kind of cheesecloth is a takes more effort. I remember hearing someone at UL say that for this type test, a special "UL Cheescloth" was needed, one that had a non-standard threadcount. I would suspect, based on other UL type tests specs, that this special cheescloth is manufactured the same way that ordinary cheesecloth was manufactured in the early 20th century. :-) Bob Richards, NCT. - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
