What does ASTM E84 mean?
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 is Class A ASTM E84?
Both the RealWall™ and LiteBarrier™ containment systems have an ASTM E84 Class A rating, which means they have the lowest fire spread rate and minimal smoke production. It’s important to note that not all containment systems on the market have been tested; in some cases, only certain components have been tested.
Is UL 723 the same as ASTM E84?
For example, Underwriters Laboratories Inc. (UL) developed UL 723 (now called ANSI/UL 723) and the American Society for Testing and Materials (ASTM) has adopted this UL test into its own standard as ASTM E84. In summary, these four standards are equivalent.
Can ULC S102 vs ASTM E84?
Each ASTM E84 test produces FSI and SDI, while each CAN/ULC-S102 test produces Flame Spread Value (FSV) and Smoke Developed Value (SDV). Additionally, three or more tests performed on the same material for CAN/ULC-S102 produce averaged values to create Flame Spread Rating (FSR) and Smoke Developed Classification (SDC).
What is the difference between Class A and Class C fire rating?
Class A fire retardants have a flame spread rating of between zero and 25. These materials are effective against severe fire exposure. Class C fire retardants have a flame spread rating of between 76 and 200. These materials are effective against light fire exposure.
What does UL 723 mean?
Surface Burning Characteristic of Building Materials test
The UL 723 Surface Burning Characteristic of Building Materials test is a standard of Underwriters Laboratories (UL) that measures the burning properties, or fire resistance, of building materials that may be exposed to flames.
What is a 25 50 fire rating?
The flame spread and smoke developed index results are reported on a scale from 0 (cement board) and 100 (red oak). The flame spread index (FSI) for pipe and duct insulation used in an air plenum must be 25 or less and smoke developed index (SDI) 50 or less, commonly referred to as “25/50” rated.
Is ASTM E84 accepted in Canada?
2 as applicable, or as permitted by Appendix D. The Canadian standard CAN/ULC-‐S102 and US standard ASTM E84 (UL 723) utilize the same tunnel apparatus designed to test products mounted in a ceiling position. However, CAN/ULC-‐S102.
Can ULC S102 flame spread ratings?
The CAN/ULC-S102 test, when conducted in triplicate, reports Flame Spread (FS) and Smoke Development (SD) values for the specific product or assembly evaluated. The flame propagation along the material’s exposed surface is visually observed and average Flame Spread value determined.
What NFPA 275?
NFPA 275 (Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used over Foam Plastic Insulation) is an approved test standard per AC 377 for equivalent thermal barriers that incorporates both a temperature transmission fire test and a fire integrity test.
What NFPA 286?
NFPA 286: Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth.
What can I use instead of ASTM A582?
Appropriate alternatives to Astm A582 grade 416 stainless steels are given in the table below: The high machinability of 416 can be sacrificed to gain better corrosion resistance and formability. A slight drop in machinability to gain better availability. Grade 303 is non-hardenable.
What is the purpose of the ASTM E84 test?
The purpose of the test is to determine the relative burning behavior of a material and assign a class / grade based on the testing results (acceptance criteria outlined below). How is ASTM E84 testing performed?
What is the ASTM E 84 Flame Spread Index?
ASTM E 84 Standard test method for surface burning characteristics of of building materials. The flame spread Index and Smoke Developed Index values obtained by the ASTM E 84 test are used by code officials and regulatory agencies in the acceptance of interior finish materials for various applications.
What’s the difference between ASTM E-84 and ulc-s102?
The main differences between the US method ASTM E-84 and the Canadian method CAN/ULC-S102 have to do with the mounting of the test samples in the Steiner Tunnel and the number of samples tested. ASTM E-84 is performed with the sample mounted to the top of the testing chamber (as described above) and a single sample is tested.
