This Part of BS 3142 specifies the sampling procedure, requirements and test methods for cokes at producers’ works, intended for use in coke-burning openable and closed domestic appliances and open fires operating with fan-assisted primary air.

For this reason a combustion test on the S coke is regarded as providing adequate control of the quality of the D coke and no separate combustion test of the D coke is required by this Part of BS 3142.
NOTE 2 The cokes may be dispatched in weighed bags and/or in bulk.
NOTE 3 The titles of the publications referred to in this Part of BS 3142 are listed on the inside back cover.
