适用范围：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 in-organic filler. Type MF D —Impact resistant Example: Melamine-formaldehyde resin with chopped cotton-cloth filler. 2 These types have been further sub-divided into grades based on property levels and requirements, as follows: Grade UF A10 Grade UF A11} Substantially alpha-cellulose-filled material Grade UF A20 Substantially woodflour-filled material Grade MF B10 Substantially alpha-cellulose-filled material Grade MF B11 Substantially alpha-cellulose-filled material with limited for-maldehyde migration Grade MF B12 Substantially alpha-cellulose-filled material with limited for-maldehyde migration for injection-moulding applications Grade MF B20 Substantially woodflour-filled material
