Motorette test Sealed tube test The total time to complete a sealed tube test takes several months due to time taken for collecting samples from all plants. For alternators to be UL 1004 recognized the insulation system is required to be UL 1446 compliant. A product investigation by UL typically involves testing of product samples.
Overview. One way to obtain a reliable electrical insulation system (EIS) is to adopt a system that has already undergone full thermal aging, also known as long-term thermal aging, and sealed-tube testing. Motorette test Sealed tube test The total time to complete a sealed tube test takes several months due to time taken for collecting samples from all plants. For alternators to be UL 1004 recognized the insulation system is required to be UL 1446 compliant. A product investigation by UL typically involves testing of product samples. FAET laboratory participating in UL THIRD PARTY TEST DATA PROGRAM, is able to execute the Sealed Tube Test for the UL Electrical Insulation System Modify. The participation allows FAET to execute tests on customers’ behalf and results are accepted by UL as if UL itself had directly obtained them, certifying the conformity to the UL 1446 standard.• UL 1446 ‐Systems of Insulating Materials – General • Derived from IEEE 117, provided information on modification of systems, including substitutions and additions. . • Materials testing –sealed tube test • Materials testing – dual temperature test • To coordinate with our loading information from IEEE C57.91, the method .
We can also modify our existing UL-1446 recognized chemistries to meet our customers specific needs, often without the requirement for a costly UL sealed tube test. This is due to the UL 746 material substitution list allowing for certain variances within a percentage of the original formulation. (fillers, color, modifiers, etc.) 120°C (Class E)
