Notes: 1. The DRE criterion presents technology capability on which approval of the technology is based. It does not always reflect the day-to-day performance achieved, which in itself will be controlled by national minimum standards.

2. Concentrated sources refer to virgin, recovered and reclaimed ozone-depleting substances.

3. Dilute sources refer to ozone-depleting substances contained in a matrix of a solid, for example foam.
