Saturation Diving
Saturation diving is the diving technique used during diving operations where the diver has reached the full saturation state for the pressure and breathing mixture being used. When this state has been reached the time required for decompression is not further increased in relation to the duration of the dive.

Definition(s)
Saturation Diving Technique
“Saturation diving technique” means a diving procedure that essentially equilibrates the total pressure of inert gases in the body of a diver with the ambient pressure and allows extended periods of bottom time without additional decompression time required (technique de la plongée à saturation).

Scale
Ordered set of values, continuous or discrete, or a set of categories to which the attribute is mapped. [SOURCE: ISO/IEC 15939:2007]- Note 1 to entry: The type of scale depends on the nature of the relationship between values on the scale. Four types of scale are commonly defined:
- nominal: the measurement values are categorical;
- ordinal: the measurement values are rankings;
- interval: the measurement values have equal distances corresponding to equal quantities of the attribute;
- ratio: the measurement values have equal distances corresponding to equal quantities of the attribute, where
- the value of zero corresponds to none of the attribute.
