Nautical fittings: changes due to the new ISO 9093-2020 standard 

In operation since December 2020, the new ISO 9093 standard dedicated to nautical fittings presents different and essential updates compared to the previous ISO 9090 standard.
The standard specifies the requirements for through-hull fittings, hull valves, connections for hoses, their fittings and their installation in small units having a hull of up to 24m in length.

All parts and components of small vessels (from embarkation lines and water discharge, to drainage water outlets) must respond to specific requirements, in respect of the characteristics of the materials, resistance, test and use of same. Specifically:

Material Requirements
The materials used for the fittings (valves, through-hulls, hose adaptor and fittings used below the waterline) must be resistant to corrosion regardless of the fluid conveyed.

Combination of materials
Metal materials, which combined (for example when using metal clamps) can lead to galvanic corrosion, must be isolated. The use of non-metallic materials must bear in mind correct seizure.

Resistance to mechanical stress
Non-metallic valves, through-hulls and hose connectors must meet the prescribed strength test.

Operating temperatures
The operating temperature range is defined from 0 ° C to 60 ° C.

The standard moves exactly in the direction brought forward by BUCCHI S.r.l, in the successful choice of using technopolymer products for the nautical sector, more advantageous and efficient than traditional metal fittings: all BUCCHI products for use on pleasure boats with a length of less than 24 meters are subject to the inspection provided for in ISO 9093 and are certified BUREAU VERITAS and respond effectively to the resistance tests and to the range of operating temperatures required by the standard.
