Regulatory Compliance
These data link modules are
intended to enable commercial
system designers to develop
equipment that complies with the
various international regulations
governing certification of Infor-
mation Technology Equipment.
Additional information is available
from your Hewlett-Packard sales
representative.
All HFBR-1119T LED transmitters
are classified as IEC-825-1
Accessible Emission Limit (AEL)
Class 1 based upon the current
proposed draft scheduled to go
into effect on January 1, 1997. AEL
Class 1 LED devices are consid-
ered eye safe. See Application Note
1094, LED Device Classifications
with Respect to AEL Values as
Defined in the IEC 825-1
Standard and the European
EN60825-1 Directive.
The material used for the housing
in the HFBR-1119/-2119 series is
Ultem 2100 (GE). Ultem 2100 is
recognized for a UL flammability
rating of 94V-0 (UL File Number
E121562) and the CSA (Canadian
Standards Association) equivalent
(File Number LS88480).
