Recommends procedures and equipment for sampling water and steam in boiler plants. Does not apply to the sampling of water and steam in nuclear power plants. Includes definitions, tables and diagrams.

This part of ISO 5667 recommends procedures and equipment for sampling water and steam in boiler plants including examples of sampling apparatus, to provide samples for physical and chemical analysis that are representative of the main body of water or steam from which they are taken.

The procedures for sampling water apply to

• raw water;
• make-up water;
• boiler feed water;
• condensate;
• boiler water;
• cooling water.

The procedures for sampling steam cover both saturated and superheated steam.

This part of ISO 5667 does not apply to the sampling of water and steam in nuclear power plants.

Figure 2 to Figure 6 are only given as examples of sampling apparatus.
