The Life Safety Code (NFPA 101) [5] and Section 803.1 of the International Building Code limit finishes for interior walls and ceilings to materials in three classes (A, B, or C, with A being the lowest flame spread and C being the highest) and gives greater restrictions for certain rooms:
The test was developed in 1944 by Al Steiner of Underwriters Laboratories, and has been incorporated as a reference into North American standards for materials testing as tests ASTM E84, NFPA 255, UL 723 and ULC S102. These standards are in widespread use for the regulation and selection of materials for interior building construction ...
The ASTM standard E84 defines a standard test method for surface flame spread and smoke density measurements. [2] A smoke-developed index of less than 450 is required by IBC section 803.1 at interior walls and ceilings for all surface materials except trim.
This is the rating required to protect microfilm, microfiche, and other film-based information storage media. Above 150 °F (65.5 °C) film is distorted by the heat and information is lost. A Class 150-2 Hour vault must keep the temperature below 150 °F. for at least two hours, with temperatures up to 2,000 °F. (1,093.3 °C) outside the vault.
The Shikkui Surface Coatings have been tested in accordance with the ASTM International standards by accredited testing laboratories in the United States. • Fire Resistance (ASTM E84) Class A (Type I in other codes) • VOC Content (ASTM D3960) Zero-VOC material • Shore D Hardness (ASTM D2240) 61-85 (depending on product)
Lumber is a sustainable and environmentally friendly construction material that could replace modern building materials (e.g. concrete and steel) given its structural performance, capacity to fixate CO 2 and low energy demand during the manufacturing process. [48] Substituting lumber for concrete or steel avoids the carbon emissions of those ...
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes.
