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.

UL – B Standard for Polymeric Materials – Long Term Property Evaluations | Standards Catalog
The list of tests can be used to evaluate all types of chemistries; such as thermoplastic polymers, thermoset polymers, PA 6, PAPolycarbonates, ABS, Epoxy, Polyurethane, Polyesters, Polypropylene, and ul 746b all types of polymeric materials.
For UL B tests the ul 746b requirements are for thermal aging to be started at four or more elevated temperatures. Charles, MO,http: Ul 746b to UL A and B for more details. A series of lectures and classroom exercises have been designed to help you develop a thermal aging program ul 746b your material.
This usually means the test specimens are to be tested are to undergo some length of thermal aging prior to testing.
This does not mean that all long term thermal aging projects can be completed within the minimum hour requirement; the uul of time needed for completion is to be agreed upon by all parties involved.
UL Knowledge Services accepts the following forms of payment uk registration: Objectives Define what RTI is and is not Describe how U, values are utilized in the selection of a plastic in an end-product investigation Describe the process for selecting a control material Determine the number ul 746b samples needed for an LTTA investigation Explain how ul 746b temperatures ul 746b selected Generally describe the data analysis mechanism.
The knowledge you gain from this workshop will help facilitate the development of a thermal uo test program, helping you achieve the ratings you need as quickly as possible.

Description The purpose of this one-day workshop is to increase your understanding of the temperature ratings assigned to a ul 746b material, and how those ratings are assigned.
Workshops – Latin America. More common physical properties include tensile strength; ul 746b strength; tensile, izod or charpy impact; dielectric strength, and flammability. Ul 746b can be 746 on test specimens which have undergone various pre-conditioning or even some length of thermal aging.
The other parts of this group are outside of the scope of testing conducted in our laboratories.
The most common minimum length of time for which the thermal aging is to be conducted is hours. UL B suggests several methods for extrapolating ul 746b discrete data generated in testing to the appropriate time that defines the thermal index temperature, but, in general, kinetics equations are employed to predict property maintenance over extended time at ul 746b use temperatures.

Ul 746b can be ul 746b than one Thermal Index for a material, each based on a different physical property. Critical physical properties, and either multiple temperatures or multiple times a minimum of 4 temperatures or times must first be defined to satisfy the intended purpose of the testing.
The samples are removed from the ovens after the appropriate time intervals, and the physical properties are determined. Target Audience Research and development staff Compliance engineers Product support staff Laboratory managers This course is currently provided as a Private workshop.
