41、e This European Standard is applicable to fire extinguishing powders for fire classes A, B and C. It specifies, by means of defined test methods, minimum requirements for the chemical and physical properties and minimum extinguishing capabilities. Requirements are also specified for the information
42、and data to be given by the supplier. This European Standard is not applicable to powders for class D fires. NOTE 1The classification of fires is given in EN 2. NOTE 2Some countries have national standards for class D powders. 2 Normative references This European Standard incorporates by dated or un

47、 its characteristics NOTE 1In North America and some other countries, the term “ dry powder” is used to denote special metal fire extinguishing agents and the term “ dry chemical extinguishing agent” is used to denote the extinguishing medium specified in this European Standard. NOTE 2When it is use
48、ful to indicate the class of fire for which a powder is designed, capital letters may be added before the term. The letters used in this European Standard are those defined in EN 2. Example: BC powder is designed to extinguish class B (liquids or liquefiable solids) and class C (gases) fires; ABC po
49、wder is designed to extinguish class A (solids which form glowing embers), class B and class C fires. 3.2 batch single charge of powder in the processing equipment that has been made homogeneous by subjection to the same unit and physical processing 3.3 lot one or more batches, but not more than 25 t of powder, manufactured to the same formulation by the same manufacturing process and under the same environmental condit
