Anotace textu normy ČSN EN ISO 9093-1   (325023)

This part of IS0 9093 specifies requirements for metallic through-hull fittings, seacocks and hose fittings that specifically form part of water intake and discharge lines, and for wet exhaust outlets used in small craft of up to 24 m length of hull. Through-hull fittings for other purposes are not covered.

This part of IS0 9093 applies to seacocks and through-hull fittings with cylindrical pipe threads in

accordance with IS0 228-1, and with joints for conical pipe threads in accordance with IS0 7-1, with nominal diameters of l/4 in, 3/8 in, l/2 in, 3/4 in, 1 in, 1 l/4 in, 1 l/2 in, 2 in, 2 l/2 in, 3 in or 4 in.

NOTE 1: The reasons for developing this part of IS0 9093 are that detail dimensions of components of water intake and discharge lines, and wet exhaust outlets passing through a craft hull differ considerably, thus limiting the interchangeability of these parts.
