the standard contains three coating designations. the ul 746b standard distinguishes between three sub- categories of the rti: electrical rti which relates to electrical insulating performance. the basics of commercial equipment certification marks. according to underwriters laboratory: relative temperature index ( rti) is the maximum service temperature for a material where a class of critical property will not be unacceptably compromised through chemical thermal degradation. ul standard for safety polymeric materials – long term property evaluations. traditional fr- 4s option for abbreviated testing. hvtr cti ( mils) ( mm) ul746b class rating rating rating rating rating rating 7 0. may be of non- rip construction with measurements made on untorn samples. ul 746b or equivalent standards. lumirror™ heat resistant grades demonstrate excellent heat and hydrolysis resistance thanks to their specially designed raw material to reduce oligomerization. standard for polymeric materials - long term property evaluations. ul standard edition 7 published date: febru last revision: novem ansi approved: novem dod approved: novem. together with the standards mentioned. 1 – tests same as fr- 4. eltek labs conducts testing to this standard for various types of polymeric materials, such as pa 6, pa 6- 6, polycarbonates, abs, epoxy, polyurethane, polyesters, polypropylene, and more. ul 746b isbnpolymeric materials – long term property evaluations. the following are iec standards, which are used worldwide and are based on ul standards. different ul and international standards are directly related to the evaluation of polymeric materials. mechanical strength rti which relates to mechanical performance without impact. an introduction to the underwriters laboratory. acquisition is planned for the future. these property changes are generally investigated by means of a mechanical shock ul746b test and quasi- static and electrical measurements. conformal coating is the most difficult designation to achieve and comprises both dielectric and fire retardance testing. single conductor with extruded insulation. ul 746c: standard for polymeric materials – use in electrical equipment evaluations. are there any white type films that have acquired ul flame retardancy standards? they call it relative temperature index or rti. the heat resistant pet is certified as ul746b class b. appliance wiring material ul 758. types of ul labels and marks. abbreviated testing, section 8. these requirements cover long- term test procedures to be used for the evaluation of materials used for parts intended for specific applications in end products. summary of topics. purchase options get update alerts. modified fr- 4s require full testing. material must compare to ul/ ansi ir reference spectra. standards for evaluating plastics. ul bulletin edition 5 published date: decem last revision: febru. extruded etfe, 2 mils minimum average thickness, 1 mil minimum thickness at any point. ul 746b: standard for polymeric materials – long term property evaluations. ul746bは米国の民間機関が定める電気製品の耐熱性の安全規格です。 東レでは、 petフィルム ルミラー ® 、 ppsフィルム トレリナ ® 、 アラミドフィルム ミクトロン ® などのフィルム製品でul746bを取得しています。. ul 746b | ul standards & engagement | ul standard | edition 5 | polymeric materials - long term property evaluations | published date: aug | ansi approved: febru. 24 awg - 1 awg, solid or stranded. subject 746a ( 94, 746b, 746c, 746d, 1692, 1694). 33 vtype e56 ul ratings astm d374 astm d374 ul 94 ul746a ul746a ul746b ul746b ul746a ul746a. mechanical impact rti which relates to mechanical performance with impact. 36 awg - 10 awg solid or stranded. to satisfy the requirements in ul 746s, recycled materials must meet horizontal burn test requirements, water exposure limits, and long- term tensile strength testing. the designation is ul746b. this includes the effects of thermal aging and relative thermal indices in assessing the material' s aging, degradation, and endurance. ul 746b | ul standards & engagement | ul bulletin. for white types, lumirror™ e20 at 38, 50, and 75 μm have obtained the ul94 vtm2. the test ends when the property value in question falls below the minimum threshold ( 50% of the original value). the tests include mechanical, electrical, flammability, and thermal aging properties. ul 746b is a standard for long term property evaluations of polymeric materials, such as plastics, thermosets, and rubbers. x10s has acquired the ul746b long- term heat resistance standard class b ( 130° c), but it has not acquired any flame retardancy standards. ir, tga, flame, ash, flexural strength properties must comply with ul746e. ul 746b | ul standards & engagement | ul red line | edition 5 | polymeric materials - long term property evaluations | published date: octo | ansi approved: octo. further reading on ul labels and marks. cable may have 0. astm d374 astm d374 ul 94 ul746a ul746a ul746b ul746b ul746a ul746a thickness thickness flame hwi hai rti elec. maximum web width, 13 mils minimum web thickness. the ul746e standard comprises a series of tests meant to evaluate whether a conformal coating can withstand sudden electrical surges and maintain its dielectric integrity. this standard utilizes generic relative thermal indexes ( rti) set by ul746b as ascertained by ul746a’ s infrared analysis testing. the ul catalog of standards. the following standards are directly related to the evaluation of polymeric materials. two to 100 conductors laid parallel and in one plane. equipment may carry a number of different markings to designate compliance with certain standards. 0 plus halogen content testing. 105 deg c, 600 vac. extruded xlpe, 9 mils minimum average thickness, 8 mils minimum thickness at any point after rip.
