This standard prescribes the methods of sampling and test for phenolic moulding materials. The tests covered are for determining apparent density, density of moulding and bulk factor, time of flow, shrinkage of moulding, tensile strength, impact strength, cross-breaking strength, water absorption, acetone soluble matter before and after moulding, free phenols, free ammonia and ammonium compounds, temperature of deflection under load, plastic yield, electric strength, surface resistivity after immersion in water, volume resistivity and power factor and permittivity.
