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. These cokes have an overall nominal aperture size range of 10.0 mm to 45.0 mm in accordance with the square aperture plate in Table 3 of BS 410:1986 and are classified as follows:

S (singles): nominal size range 10.0 mm to 25.0 mm square hole

D (doubles): nominal size range 16.0 mm to 45.0 mm square hole

The specification applies to cokes produced under the following manufacturing arrangements:

  1. S only;
  2. S and D simultaneously from the same coals.

NOTE 1 When a plant is producing S and D coke simultaneously the reactivities of these cokes will be similar. 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.
