1.1 This International Standard establishes a specification applicable to four types of aminoplastic moulding materials, classified according to use, as follows: Type UF A – General purpose Example: Urea-formaldehyde resin with cellulose filler. Type MF B – Hot-water resistant Example: Melamine-formaldehyde resin with cellulose filler. Type MF C – Heat resistant and electrical Example: Melamine-formaldehyde resin with inorganic filler. Type MF D – Impact resistant Example: Melamine-formaldehyde resin with chopped cotton-cloth filler. 1.2 These types have been further sub-divided into grades based on property levels and requirements, as follows:
