DATAMATH CALCULATOR MUSEUM |
During
evaluation of the rare TI-5310 we noticed a small,
very important detail of the calculator. It was tested according to the UL
Standards common in the United States. And just this little logo on the
nameplate spills out the secret! Every company submitting a product to
Underwriters Laboratories Inc. (UL) receives an UL-File Number like E12345.
Driven by the wide usage of the Internet the www.ul.com
website provides the service of online access to the UL Certification
Informations.
Just try out the UL-File Number E42662
printed below the UL-Logo and you'll get important informations.
The following database lists all known UL-File numbers located on desktop
calculators carrying the Texas Instruments brand. Up to now we are not sure
which models are OEM products and which ones were developed by Texas Instruments
and manufactured by the Contract Manufacturer.
The database references to known companies:
