DATAMATH  CALCULATOR  MUSEUM

UL Listed Desktop Calculators


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: 

bulletToshiba TEC Corp.
bulletKinpo Electronics Inc.
bulletINVENTEC APPLIANCES (SHANGHAI) CO LTD
bulletLEO ELECTRONICS (HK) LTD
