ISO 13909-3 specifies procedures for the mechanical sampling of coal from stationary lots, for example, from wagons, barges, ships, and stockpiles. These procedures are to be used when it is not possible to sample the lots during loading or discharge according to ISO 13909-2. Procedures for sample preparation are given in ISO 13909-4.
ISO 13909-3 is applicable to mechanical sampling from stationary coal lots, to obtain samples from which test samples for the determination of moisture, and for general analysis including physical and chemical tests, can be prepared in accordance with the requirements and recommendations set out in ISO 13909-4.
In this part of ISO 13909, the principles and procedures for designing a sampling scheme are given, together with typical examples of applications; in addition, practices for the execution of sampling in different sampling situations are described.
Note: The methods described are limited to those on which it is possible to conduct a test for bias.
ISO 13909-3 on hard coal and coke- Sampling from stationary lots 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.
ISO 13909-3 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 13909-3:2016 supersedes ISO 13909-3:2001. BS ISO 13909-3:2016 has been technically revised.
