ISO 13909-2 specifies procedures and requirements for the design and establishment of mechanical samplers for the sampling of coal from moving streams and describes the methods of sampling used.
Note: ISO 13909-2 does not cover mechanical sampling from stationary lots which is dealt with in ISO 13909-3.
ISO 13909-2 on hard coal and coke- Sampling from moving streams is useful for:
The purpose of taking and preparing a sample of fuel is to provide a test sample which, when analyzed, will provide test results representative of the lot sampled.
The first stage in the design of the scheme is to identify the coal to be sampled. Samples may be required for technical evaluation, process control, quality control and for commercial reasons by both the producer and the customer. It is essential to ascertain exactly at what stage in the coal-handling process the sample is required and, as far as practicable, to design the scheme accordingly.
ISO 13909-2 provides detailed operating protocols to ensure uniform and consistent collection, weighing and processing of samples. This includes the preparation of facilities and assembly of all equipment necessary for collection of samples, processing and packaging them, and transporting them from collection and weighing sites to processing facilities and to the laboratory for analysis in efficient manner.
BS ISO 13909-2:2016 supersedes ISO 13909-2:2001. BS ISO 13909-2:2016 has been technically revised.
