1 Scope<\/b><\/p>\n
This International Standard is applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions.<\/p>\n
NOTE 1\u00a0The equipment is not designed to generate heat.<\/p>\n
NOTE 2\u00a0The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the <\/p>\n
THERMAL-LINK<\/p>\n
, as well as upon the current which it is carrying.<\/p>\n
This standard may be applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such <\/p>\n
THERMAL-LINKS<\/p>\n
are comparable with those in this standard.<\/p>\n
This standard may be applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or <\/p>\n
PORTABLE EQUIPMENT<\/p>\n
, irrespective of its position.<\/p>\n
Annex H of this standard is applicable to <\/p>\n
THERMAL-LINK<\/p>\n
packaged assemblies where the <\/p>\n
thermal-link(s)<\/p>\n
has already been approved to this standard but packaged in a metallic or non-metallic housing and provided with terminals\/wiring leads.<\/p>\n
This standard is applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
with a <\/p>\n
RATED VOLTAGE<\/p>\n
not exceeding 690 V a.c. or d.c. and a <\/p>\n
RATED CURRENT<\/p>\n
not exceeding 63 A.<\/p>\n
The objectives of this standard are:<\/p>\n<\/p>\n
a)\u00a0to establish uniform requirements for <\/p>\n
THERMAL-LINKS<\/p>\n
,<\/p>\n<\/li>\n
b)\u00a0to define methods of test,<\/p>\n<\/li>\n
c)\u00a0to provide useful information for the application of <\/p>\n
THERMAL-LINKS<\/p>\n
in equipment.<\/p>\n<\/li>\n<\/ol>\n
This standard is not applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
used under extreme conditions such as corrosive or explosive atmospheres.<\/p>\n
This standard is not applicable to <\/p>\n
THERMAL-LINKS<\/p>\n
to be used in circuits on a.c. with a frequency lower than 45 Hz or higher than 62 Hz.<\/p>\n
