Look Inside. UL B. 4th Edition, March 30, Complete Document. UL Standard for Safety Polymeric Materials – Long Term Property Evaluations. Includes. These revisions to ANSI/UL B are being issued to adopt the following requirements: Generic Thermal Index for Polyether Ether Ketone (PEEK). Generic . The Relative temperature index (RTI) is a characteristic parameter related to the thermal degradation of plastic materials. The RTI is part of the thermal-aging program of the UL B standard from.

Specimens for testing are dependant upon the physical property or ul 746b that are the test criteria. Workshops – Latin America. Charles, MO Email Us. A control material, with demonstrated end use performance, may be used to enhance the reliability of the data analysis. UL Knowledge Services reserves the right ul 746b limit workshop attendance strictly to the foregoing. Ul 746b series of lectures and classroom exercises have been designed 746h help you develop a thermal aging program for your 76b.
Subscribe to our YouTube Channel. For UL B tests the general requirements are for thermal aging to be started at four or more elevated temperatures. Thermal Index is an important property for materials 7446b will be used in applications that must ul 746b significant spans of time ul 746b elevated temperatures – for example, outdoor applications and electronic components and housings.
There can be more than one Thermal Index for a material, each based on a different physical property. You can unsubscribe anytime.
This usually means the test specimens are to be tested are to undergo some length of thermal aging uo to testing. The ul 746b test sampling method is ul 746b Fixed Time Frame Method. Standards can be obtained from appropriate standards ul 746b. Click here for terms and conditions If you’re interested in taking this course, you can click the ‘I’m Interested’ button below.

The list of tests can be used to evaluate all types of chemistries; such ul 746b thermoplastic polymers, thermoset polymers, PA 6, PAPolycarbonates, ABS, Epoxy, Polyurethane, Polyesters, Polypropylene, and basically all types of polymeric materials. Refer to UL A and B for more details. Description The purpose of this one-day workshop is to increase your understanding of the temperature ratings assigned to a polymeric material, and how those ratings are assigned.
Test can be performed on test specimens which have undergone various pre-conditioning or ul 746b some length of thermal aging. Critical physical ul 746b, and either multiple temperatures or multiple times a minimum of il temperatures or times must first be defined to satisfy the intended ul 746b of the testing.

The purpose of this one-day workshop is to increase your understanding ul 746b the temperature ratings assigned to a polymeric material, and how those ratings are assigned. Ul 746b does not mean that all long term thermal uul projects can be completed ul 746b the minimum hour requirement; the length of time needed for completion is to be agreed upon by all parties involved. UL Knowledge Services workshops are designed for and intended to serve individuals using and relying upon UL services.
In addition, UL Knowledge Services reserves the right to u, reschedule or cancel any workshop at any time.

The other parts of this group are outside of the scope of testing conducted in our laboratories. More 746 physical properties include tensile strength; flexural strength; tensile, izod or charpy impact; ul 746b strength, and flammability.
The knowledge ul 746b gain from this workshop will help facilitate the development of a thermal aging test program, helping you achieve the ratings you need as quickly as possible. Contact us if you are interested in this workshop. The ul 746b common minimum length of time for which the thermal aging is to be conducted is hours. Ul 746b test samples are aged in hot air recirculating ovens. UL B suggests several methods for extrapolating the discrete data generated in testing to the appropriate time that defines the thermal index temperature, but, in general, kinetics equations are employed ul 746b predict property maintenance over extended time at end use temperatures.
