IS 2036 : 1995 Phenolic Laminated Sheets - Specification

1 Scope

1.1 This standard prescribes the requirements and methods ofsampling and test for phenolic resin bonded laminated sheets of oneclass in which the mechanical properties in directions A and B areof the same order, with asbestos, woven cotton fabric and cellulosepaper reinforcements and covers seventeen types.

1.2 This standard covers only sheets of a nominal thickness from0.4 to 50 mm for cellulose paper based types and nominal thicknessfrom 0.4 to 100 mm for woven cotton fabric and asbestos reinforcedtypes.

1.3 This standard prescribes requirements for phenolic resinbonded paper laminated sheet sanded on one side, of nominalthickness in the range 0.4 mm to 3 mm inclusive.

Note - It is permissible for sheet complying with this standardto contain additives, for example colouring matter.
