Robert, Both these standards cover Explosion Protection Techniques - Intrinsic Safety. They have absolutely nothing to do with UL 1950. The UL standard for "intrinsic safety" is UL 913 but it is not equivalent to nor harmonized with these other two standards. I doubt that any industrial PC is or can be made "intrinsically safe." The normal protection methods for industrial PC's are "flameproofing" or "air purging." This is a specialty and there are companies that make special enclosures for PC's that must be located in "flammable atmospheres". One that comes to mind is Daisy Systems.
- Mike Rains From: Robert Terry[SMTP:[email protected]] Sent: Monday, September 30, 1996 3:15PM To: [email protected] Subject: Australian Standard I received a recent request from a potential customer for an industrial PC that meets the following 2 specifications. Australian Standard 2380.7-1987 and IEC 79-11. I am not familiar with these standards and would appreciate any information on these standards. Ideally, I would like to know what these standards cover, as well as how close the US counterparts come to meeting them. For example, if these are product safety standards for ITE, how close does UL1950 come!! Thanks in advance for any information that you guys have on these standards! begin 600 WINMAIL.DAT M>)\^(A(+`0:0" `$```````!``$``0>0!@`(````Y 0```````#H``$(@ <` M& ```$E032Y-:6-R;W-O9G0@36%I;"Y.;W1E`#$(`0F `0`A````-34S1$%$ M1#,X-D9$,40Q,#E!-#4T03@Y,41"-D)!,#<`2P<!(( #``X```#,!PH``0`' M`!,`$ `"``H!`06 `P`.````S <*``$`!P`/`!T``@`3`0$-@ 0``@````(` M`@`!!( !`!@```!213H@075S=')A;&EA;B!3=&%N9&%R9 !6" $#D 8`\ 8` M`!@````#`"X``````$ `.0# 2FK:B:^[`1X`< `!````& ```%)%.B!!=7-T M<F%L:6%N(%-T86YD87)D``(!<0`!````%@````&[KXG:)].M/5C]AA =FD5* MB1VVN@<```,`!A!B&"=I`P`'$"T$```>``@0`0```&4```!23T)%4E0L0D]4 M2%1(15-%4U1!3D1!4D130T]615)%6%!,3U-)3TY04D]414-424].5$5#2$Y) M455%4RU)3E1224Y324-3049%5%E42$592$%614%"4T],551%3%E.3U1(24Y' M``````,`$! ``````P`1$ $````"`0D0`0```)($``".! ``%0@``$Q:1G4` ML7!J_P`*`0\"%0*D`^0%ZP*#`% 3`U0"`&-H"L!S973N,@8`!L,"@S(#Q@<3 M`H-&,P/%`@!P<G$2(G.H=&5M`H,T$PU]"H"+",\)V3L7GS(U-0* ;PJ$"S<2 M\@P!8P! !_%B.020="P*A0J+#- Q- 8T#? :KR!";W1H9B ?( >092 5, !P M9!<+$00@!:!V!) @17C-"U!O`) "("!0`V 50%1C="$25 60: ,`<>,*4 0@ M+2!)`C %$ "!RF,&`682`'DN(? ?8*QY(!'
