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.

Requirements and test methods; EN 13595-1:2002: Protective clothing for professional motorcycle riders. Jackets, trousers and one piece or divided suits.
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.
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 ...
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]
Gypsum is a mineral and non-combustible building material (a class A1 building material in accordance with the German DIN 4102, the European EN 13501 or the British BS 476 or the American ASTM E119) consisting of calcium sulphate dihydrate (CaSO 4 ·2H 2 O). Because of the stored water, gypsum is a good fire protection building material. In the ...
