1 Scope
This document provides information for the design of composite cylinders related to
impact testing and service experience with impact, including:
-
— low energy impact, which can result from events that can occur during handling or
working around cylinders;
-
— high energy impact, which can result from accidents during transportation, or impact
by large objects with velocity;
-
— drop impact, which can result from handling, where cylinders are dropped or tipped
over; and
-
— high velocity impact, which can result from high energy impact by a small object,
such as gunfire, and demonstrates non-shatterability of the cylinder or tube.
Where appropriate, field experience relevant to testing requirements is provided.
NOTE Unless otherwise stated, the word “cylinder” refers to both cylinders and tubes.
