What is BS 3142-2 - Cokes for domestic openable and closed appliances and open fires with fan-assisted primary air about?
BS 3142-2 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:
- S only
- S and D simultaneously from the same coals
Note1: 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.
Who is BS 3142-2 - Cokes for domestic openable and closed appliances and open fires with fan-assisted primary air for?
BS 3142-2 on cokes for domestic openable and closed appliances and open fires with fan-assisted primary air is useful for:
- Coal industry
- Producers of coke
- Domestic appliances manufacturers
- Quality control personnel
- Testing laboratories
- Producers of coke
Why should you use BS 3142-2 - Cokes for domestic openable and closed appliances and open fires with fan-assisted primary air?
There are many fuels available in the market, but different suitability criteria need to be fulfilled according to the appliance concerned. For domestic openable and closed appliances and open fires smoke control, quality of coke, ease of use, etc are some important parameters, to be taken into account.
BS 3142-2 provides guidance on sampling and preparation of samples, total moisture, combustion test, quality control, calibration of the thermostat, schematic of Test setting for boiler performance tests. This enables you to assess the suitability of coke for domestic openable and closed appliances and open fires with fan-assisted primary air.
The producers can ensure that the samples taken reflect the quality and consistency of all the coke dispatched is in accordance with BS 3142-2.
What’s changed since the last update?
BS 3142-2:1990 supersedes BS 3142-2:1965. BS 3142-2:1990 includes some changes with respect to BS 3142-2:1965. These include:
- The standard is extended to cover openable appliances and open fires operating with fan-assisted primary air
- The larger size of coke is designated in line with current practice
- The values and units of parameters have been metricated
- Reference to gas coke works has been deleted
- The testing and requirement for shale have been deleted
