Since coal can vary from extremely wet (water-saturated) to completely dry, special emphasis must be placed on the sampling, sample preparation, and the moisture determination itself to ensure total reliability of measurement. Therefore, this standard entails collection of the gross sample, sample preparation, and the method of determination.

the sample (the one hour collection period must be a full hour of coal flow). The sampling system should be set to collect at least the sample mass specified in the standard during one hour test periods. All of the proper protocols for sample preparation and analysis must be used and documented, and the OLA data collection must be in accordance
