hat is the difference between ASTM e2768 and CAN/ULC S102?



ASTM E2768 and CAN/ULC S102 are two different standards used in fire resistance testing. Here are the primary differences between the two:
1. Origin and Applicability:
   - ASTM E2768: This standard is developed by ASTM International, an internationally recognized organization for developing standards across various industries. ASTM E2768 is specifically for assessing the fire performance characteristics of upholstered furniture.
   - CAN/ULC S102: This standard is developed by the Underwriters Laboratories of Canada (ULC), which is responsible for developing standards primarily used in Canada. CAN/ULC S102 pertains to the surface burning characteristics of building materials and assemblies.
2. Test Methods:
   - ASTM E2768: This standard employs a full-scale, room corner test. It evaluates the fire behavior and potential fire growth on upholstered furniture within a simulated room corner scenario.
   - CAN/ULC S102: The test methods specified in this standard include the Steiner tunnel test or the radiant panel test. These methods are used to assess the surface burning characteristics of various building materials and assemblies.
3. Scope of Application:
   - ASTM E2768: It is primarily focused on assessing the fire performance of upholstered furniture, such as sofas, chairs, and mattresses. The standard includes requirements for materials used in the upholstery, including cover fabrics and fillings.
   - CAN/ULC S102: This standard is more general and covers a wider range of building materials used in various construction applications. It is applicable to interior finishes, such as wall and ceiling materials, flooring, and other surface coverings.
4. Regional Differences:
   - ASTM E2768 is widely recognized and used internationally, including in many countries outside of North America.
   - CAN/ULC S102 is primarily used in Canada and may have specific requirements and regulations aligned with Canadian building codes and regulations.
It is important to note that these standards may have their own specific requirements, procedures, and limitations depending on the context and jurisdiction in which they are applied. Consulting the respective standards and local regulations is crucial for accurate and up-to-date information regarding fire resistance testing.
