* Methods adapted to accommodate South African or local laboratory conditions
** No equivalent SANS method. [South African National Standards (SANS) numbers
mostly correspond with ISO or IEC numbers on adoption there-of].
SM = Standard Method for Examination of Water and Wastewater or (old) SABS Standard Method. The SABS methods were phased out and
replaced by the SANS system, and are referenced for information only.
- Reference Information: The International Classification of Standards (ICS) system lists standards for
Water Quality as 13.060, and Coal Quality as 73.040.
