Dear Jay:

Py co.-.= nts on th's doom~ant c:ere solicited by ~". Sherr in his letter

. of June 2-',

1971..

He should no" have done it.

I cannot find - single redee in@

eature in this worthless document.

Far from being ~..at its tit' suz~es-s, it contai=s only the nost gener-al kind of s"uff on ho-: to 'qualiz, s".:ething - an=thing.

The body of the docunent is not even specific enough to be re'aced

=c electrical equip-,.ent.:urthe..~ore, the va=io s clauses are so general.that t's essentially

=-... ossible to ceter.ine co p'iance.

=or these reasons the referenced document in its p=esent fora 's, as

~ said above, vithout e;alue.

Sincerely yaurs, St phen H. Eanauer cc:
