What is ASTM E136?
Standard: ASTM E136 – Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C. Certification Required: The International Building Code (IBC) and International Residential Code (IRC) prescribes this test for materials that are required to be non-combustible.
What is ASTM D3273?
The ASTM D3273 method is meant to evaluate fungal defacement of coated interior surfaces in an accelerated manner. The ASTM D3273 test specifically aims to establish the relative resistance of paint films to the propagation of mold and mildew under optimum fungal growth conditions.
What does 1 hour fire rating mean?
A “one-hour” fire rating is given to an assembly consisting of various building materials that can resist the exposure of a standardized fire exposure for one hour.
What materials are considered non-combustible?
Examples of non-combustible materials include steel, masonry, ceramics and certain insulating materials (such as fiberglass or mineral wool insulation). Gypsum wallboard is considered by the codes to be non-combustible although it does have a thick paper backing that is combustible.
Is there non-combustible drywall?
Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it slow down the fire. Also, because it is denser than normal gypsum and paper drywall, it takes longer for the fire to degrade it.
What is ASTM e84?
The ASTM E-84 is the standard test method for assessing the surface burning characteristics of building products to explore how the material might contribute to flame spread in the event of a fire. The test reports the Flame Spread index and Smoke Developed index of the tested product.
What are the best drywall screws?
Coarse Thread Drywall Screws Coarse-thread drywall screws work best for most applications involving drywall and wood studs. The wide threads are good at gripping into the wood and pulling the drywall against the studs. One downside of the coarse-thread screws: the metal burrs that can embed in your fingers.
What does Class C fire rating mean?
A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.
What is Class C material?
What is a Class C or Class 3 fire rating? A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.
Is Type C drywall fire rated?
Type C drywall is known as the more durable version of Type X—there are more glass fibers in this product as well as more vermiculite components, giving it a fire resistance of 2-4 hours. You can find this product at your local drywall and insulation store in 1/2” and 5/8” thickness.
How do I know if my drywall is fire rated?
Type X drywall has special core additives that allow it to be used in fire rated designs and usually comes in 5/8” thickness. Type X drywall products will have a UL/ULC Marking printed on the back of each board identifying it as a fire-resistance rated board.
