Annex A (informative) - Review of evidence
Annex B (informative) - Review of alternative methods for
managing finite-amplitude effects during field
measurement
Annex C (informative) - Parameters to quantify nonlinearity
Annex D (informative) - Tables of upper limits for mean peak
acoustic pressure for quasi-linear conditions
Bibliography
Annex ZA (normative) - Normative references to international

Sets up: - the general concept of the limits of applicability of acoustic measurements in water resulting from finite-amplitude acoustic effects; and - a method to ensure that measurements are made under quasi-linear conditions in order to minimise finite-amplitude effects.
