What is a hollow instrument?

To ensure that medical devices and instruments are properly sterilised, it is important to first determine their hollow classification so that the correct type of steriliser / steriliser cycle can be selected for the process.

Australian / New Zealand Standard AS/NZS 4815:2006 outlines the definitions for the different types of hollows. These definitions are based on the definitions in the European Standard EN 13060.  There are three definitions outlined in the standard.

1. Objects which are not hollow      2. Hollow B objects        3. Hollow A objects

1. Objects which are not hollow

Some objects, although having similar characteristics, are not subjected to the classification of a hollow object. In simple terms, objects are not hollow if the ratio of the length of the cavity to diameter is less than 1

2. Hollow B objects

AS/NZS 4815:2006 “An object whose ratio of length of cavity to diameter is greater than 1 and greater than 5”


3. Hollow A objects:

AS/NZS 4815:2006 “An object whose ratio of length of cavity to diameter is greater than 1 and less than 5”
