Moderate

Applies to all areas more than 25 Kilometres from the coast with light marine influence and or light industrial pollution.

Tropical

Tropical environments are those generally located between the tropic of Cancer and tropic of Capricorn and are subject to high levels of humidity, except where directly affected by salt spray or industrial pollution.

Severe

1. Marine - Applies to areas influenced by a moderate extent of coastal salts. Factors that should also be considered are winds, topography and vegetation. This zone generally extends from about 500 metres from the coast up to 20 km inland, depending on conditions.
2. Industrial - Applies to areas surrounding major industrial complexes inland from the sea.

Please note: this information is provided as a general guide only and other factors such as micro climatic and environmental conditions should always be taken into account when selecting an appropriate coating thickness and cleaning program. For further information refer to the standard that applies to your region (refer to specifying sapphire's colour range) or contact your local sapphire representative.
For example, approximately ninety percent of australia's and new zealand's population live in coastal regions.
