WebMaterials with a “B” rating on the UL 94 Vertical test can also be tested in the less severe UL 94 HB (for horizontal burning), which measures simply a flame spread rate. The UL 94 test is the most widely used fire test for plastic materials, especially fire retarded ones, and the results are almost always found in specifications and in data WebUL94 V-0, V-1, & V-2 Flammability Standard Vision Design Specimen Length 125 mm (5 in) x Width 13 mm (0.5 in) x Thickness [typically 0.7 mm (1/32 in) or 1.5 mm (1/16 in) or …

The LOI values of EP–DSD composites increased from 30.7% for a content of 3 wt % to 35.4% for a content of 9 wt %. When the content of DSD reached 6 wt %, a V-0 rating under the UL-94 vertical test was achieved. dynamicdatasourceproperties
UL94 HB Flammability Standard - RTP Company
WebThe UL 94 Standard provides a method for rating the ignition characteristics of plastic materials. Two UL 94 ratings that users most often run across are HB and V (V-0, V-1, or V-2). These ratings are established using small-scale tests in which approximately 5 by ½ inch samples are subject to a ¾ inch, 50 W Tirrill burner flame ignition source. UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. The standard determines the material’s tendency to either extinguish or spread the flame once the specimen has been … See more From lowest (Least flame-retardant) to highest (Most flame-retardant): • HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm See more Tests are generally conducted on a 5 × 1⁄2 in (127 × 12.7 mm) specimen of the minimum approved thickness. For 5VA and 5VB ratings, tests are performed on both bar and plaque specimens, and the flame ignition source is approximately five times as severe as … See more • Flammability • Flammability diagram • Fire test See more There are other classifications that apply to low density foam materials (HF-1, HF-2, HBF) and thin films (VTM-0, VTM-1, VTM-2). • HF … See more • UL International Thermoplastics Testing Center Website - Test methods : Combustion (fire) with animations. • The Plastics Web - … See more WebUL94 vs. UL746C Flammability and standards • There is a lot of confusion about flammability ratings what they really are? • UL 94 is a flammability standard for plastic materials, horizontal burning or vertical burning tests (HB V-2, V1, V-0) • UL94-5V is test standard for the materials which are already classified in dynamic-datasource 分布式事务
