A more recent industrial standard is the European EN 13501-1 - Fire classification of construction products and building elements—which roughly replaces A2 with A2/B, B1 with C, B2 with D/E and B3 with F. B3 or F rated materials may not be used in building unless combined with another material that reduces the flammability of those materials.
This rating is the requirement for protecting paper documents. Above 350 °F (176.7 °C) paper is distorted by the heat and information is lost. A Class 350-4 Hour vault must keep the temperature below 350 °F. for at least four hours, with temperatures up to 2,000 °F. (1,093.3 °C) outside the vault.
In the harmonized Euroclass system of reaction to fire performance of building products, wood wool boards can be classified as A2-s1, d0 according to EN 13501-1 Fire classification of construction products and building elements; Part 1: Classification using data from reaction to fire tests. [8]
A fire class is a system of categorizing fire with regard to the type of material and fuel for combustion.Class letters are often assigned to the different types of fire [1], but these differ between territories; there are separate standards for the United States (NFPA 10 Chapter 5.2.1-5.2.5), Europe (DIN EN2 Classification of fires (European Standard) ISO3941 Classification of fires ...
UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. [1] The standard determines the material's tendency to either extinguish or spread the flame once the specimen has been ignited.

Class 1 goods are subdivided further into one of 6 distinct divisions, that describes the predominant explosive hazard that exists if that article was to detonate or activate while in transport or storage. These divisions are as follows: Class 1: Explosives. Division 1.1: Explosive that has a mass explosion hazard. A mass explosion is a ...
Stronger and less porous engineering bricks (UK Class A) are usually blue due to the higher firing temperature [3] whilst class B bricks are usually red. Class A bricks have a strength of 125 N/mm 2 (18,100 lb f /sq in) and water absorption of less than 4.5%; Class B bricks have a strength greater than 75 N/mm 2 (10,900 lb f /sq in) and water ...
