What does UL 94 v0 mean?
UL-94 is the Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances. To attain the UL 94V-0 standard, samples must have met the following criteria: Burning combustion is not sustained for more than 10 seconds after applying controlled flame.
What fire rating is polycarbonate?
Polycarbonate has a classification of s1, which means that the speed or quantity of smoke is absent or very low. In addition, polycarbonate produces very little flaming droplets, which contribute to the spread of fire by igniting other surfaces, and therefore receives a d0 rating per EN 13501-1.
What are the different grades of polycarbonate?
3 Grades Available The material is available in a variety of grades such as film, flame retardant, reinforced and stress crack resistant, branched (for applications requiring high melt strength) and other speciality grades.
Is 5VA better than V 0?
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole.
What is V0 plastic?
UL 94 is a plastics flammability standard released by the Underwriters Laboratories (USA). Burning stops within 30 seconds on a vertical part allowing for drops of plastic that are not inflames. V-0. Burning stops within 10 seconds on a vertical part allowing for drops of plastic that are not inflames.
What is the best flammability rating?
UL 94-5VA Surface Burn; Burning stops within 60 seconds, test specimens MAY NOT have a burn-through (no hole). This is the highest (most flame retardant) UL94 rating. UL 94 V-2 Vertical Burn; Burning stops within 60 seconds, Flaming drips ARE allowed.
Is polycarbonate plastic fire proof?
UL 94 Flammability Rated Polycarbonate Let’s start with the UL 94 standard, which is titled “Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances.” LEXAN 9034, which is the LEXAN general purpose polycarbonate sheet, is listed as “flame-resistant” by the manufacturer.
Which is better acrylic or polycarbonate?
Polycarbonate is the stronger material at 250 times the impact resistance of standard glass. Polycarbonate offers much more resilience than acrylic, making it ideal for highly demanding applications like bullet-resistant windows. Acrylic is also easier to crack, while polycarbonate is easier to scratch.
What is the best thickness for polycarbonate?
4 and 6 mm
Polycarbonates are available in a variety of thicknesses, but the most ideal thickness that you can choose lies between the range of 4 and 6 mm. Anything lesser than that means low quality polycarbonate, which won’t help to serve you for longer.
What is the strongest polycarbonate?
Multiwall polycarbonate is just what it sounds like – layered polycarbonate sheeting that’s even more powerful than the base material in terms of unbreakability, versatility and insulation.
What is a UL 94 HB rating?
UL 94 Classification and Flame-Retardant Thermoplastics
| UL 94 Rating | Definition of Rating |
|---|---|
| HB | Slow burning on a horizontal part |
| V-2 | Burning stops within 30 seconds on a part allowing for drops of vertical flammable plastic. |
What is V0 material?
UL 94 Classification and Flame-Retardant Thermoplastics
| UL 94 Rating | Definition of Rating |
|---|---|
| V-1 | Burning stops within 30 seconds on a vertical part allowing for drops of plastic that are not inflames. |
