• — parameters related to thermal and non-thermal aspects of diagnostic ultrasonic fields;
• — methods for the determination of an exposure parameter relating to temperature rise in theoretical tissue-equivalent models, resulting from absorption of ultrasound;
• — methods for the determination of an exposure parameter appropriate to certain nonthermal effects.

NOTE In this standard where multiples or submultiples of SI units are used this is clearly stated and the usage is self-consistent.
