Get info on UL 94 Flammability test which was developed by Underwriters Laboratories for determining a specimen's relative flammability.
three tests that apply to stock shape products (sheet, rod, tube and film) and how the rating system works. This is not meant as a procedure for running the tests nor as a way of determining the acceptability of a material for a particular application.UL 94 Flammability Ratings Summary ...

To be sure, check with the UL representative assigned to the device in which the film will be used. The 94HB rating would typically be acceptable for portable, attended, intermittent-duty, household-use appliance enclosures (i.e., hair dryers) or for decorative parts. The test uses a ...

The classification is made via V-0, V-1 and V-2 rating and criteria as shown in Table 3 (Laoutid et al., 2009; Patel, Hull, & Moffatt, 2012; Wang et al., 2010). Sign in to download full-size image Fig. 7. Schematic representation of UL 94 vertical test.Reprinted from Laout...
(LOI), vertical flammability test(UL94 rating) and cone calorimetry(CONE), the best flame retardancy with a strong and well intumescent char is obtained from the sample with 1 wt% of Mg O, which has the highest LOI value of 27.9, UL94 rating of V-0 and the lowest peak heat release ...

The UL 94 test showed a V-0 rating for both materials. In the works presented in this review, for the first time at the molecular level, studies of the mechanism of action of flame-retardants in the gas phase were carried out by measuring the distribution of concentrations of radicals and...
In the case of LDPE-A (Figure 4a), FR3 was proved significantly efficient reaching a UL 94 V0 rating and a low total burning time (1.4 s). FR3 is the mixture of the triazine derivative and APP in a 1:3 ratio of the charring agent to APP with a total loading of 35 wt.%; the...
