Many thanks to those who responded to my query about the use/meanings of the
words 'shall' and 'must' in product safety standards.
Must and shall appear to be interchangeable. UL1950 uses both (couldn't make

The subject here is regarding the words 'shall' vs. 'must' in various of

product safety? I have heard there are differences, but no one can seem

Unless you have had experience creating a decent TCF and have a good example
of one, it would be wise, at least once, to use a NB. This way you would
have a nice example of a document.
