This part of ISO 12215 applies to the determination of design pressures and stresses, and to the determination of the scantlings, including internal structural members of monohull small craft constructed from fibre-reinforced plastics, aluminium or steel alloys, glued wood or other suitable boat building material, with a length of hull, LH, in accordance with ISO 8666, between 2,5 m and 24 m. It only applies to boats in the intact condition.

It only applies to craft with a maximum speed u 50 knots in mLDC conditions.

The assessment shall generally include all parts of the craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISO 12217 and are essential to the safety of the craft and of persons on board.

For the complete scantlings of the craft, this part of ISO 12215 is used in conjunction with Part 6, for details, Part 7 for multihulls, Part 8 for rudders and Part 9 for appendages and rig attachment.

The scantling determination of windows, portlights, deadlights, hatches and doors, is in accordance with ISO 12216. The structure supporting these elements is in accordance with this part of ISO 12215.

NOTE 1 Scantlings derived from this part of ISO 12215 are primarily intended to apply to recreational craft including recreational charter vessels and may not be suitable for performance racing craft.

NOTE 2 This part of ISO 12215 is based on the assumption that scantlings are governed solely by local loads.

NOTE 3 The scantling requirements of this part of ISO 12215 are considered to correspond to the minimum strength requirements of motor and sailing craft which are operated in a safe and responsible manner, having due cognisance of the prevailing conditions.

Pressures and stresses are normally expressed in pascals, kilopascals or megapascals. For the purposes of a better understanding for the users of this part of ISO 12215, the pressures are expressed in kilonewtons per square metre (1kN/m2 =1kPa) and stresses or elastic moduli are expressed in newtons per square millimetre (1 N/mm2 =1 MPa).

This part of ISO 12215 gives requirements on the scantlings of rudders fitted to small craft with a length of hull, LH, of up to 24 m, measured according to ISO 8666. It applies only to monohulls.

This part of ISO 12215 does not give requirements on rudder characteristics required for proper steering capabilities.

This part of ISO 12215 only considers pressure loads on the rudder due to craft manoeuvring. Loads on the rudder or its skeg, where fitted, induced by grounding or docking, where relevant, are out of scope and need to be considered separately.

NOTE Scantlings derived from this part of ISO 12215 are primarily intended to apply to recreational craft including charter craft.

This part of ISO 11711 provides guidance to shipboard personnel and other concerned parties on the materials, design and installation of permanent shipboard fittings used to facilitate the sampling of ballast water from the main discharge pipe on board a vessel. The guidance is limited to ships with a ballast discharge pipe size of DN 100 or greater. Smaller ballast pipe diameters will be addressed in Annex A. Sampling is intended to determine if ballast water is in compliance with regulatory discharge standards, such as during the installation of ballast water treatment equipment, periodic ballast water discharge assessments, or when a port state control inspection indicates there is a need to sample the ballast water being discharged. In addition, sample ports may need to be installed on ships used as platforms to conduct verification testing of ballast water management systems (BWMS). In this case, uptake and discharge samples would need to be collected. Guidance for installation of sample ports intended to collect uptake samples is provided in Annex B.

A sampling team will need to coordinate with the vessel to install a sample collection probe into the shipboard sample port as needed to collect ballast samples, and the port will be sealed with a blind flange at other times. ISO 11711 provides guidance on the location of sample ports to accommodate representative sampling, and it standardizes the presentation of the port to accommodate various probe configurations. Part 1 of ISO 11711 also identifies the need for a return port to the ballast line downstream of the sample collection port, which will allow processed sample water to be returned to the ballast pipe. The specific sample probe and other sample collection apparatus will be determined by the sample collection team according to the requirements of ISO 11711-2.

NOTE The distinction between the sample port discussed in Part 1 and the sample probe discussed in Part 2 is important. The sample port is a permanent apparatus designed and installed in the ship's ballast piping to accept multiple sample probe configurations. The sample probe is a temporarily installed water collection pipe designed by the sampling party to mate with the sample port and to meet the measurement objectives of the sample.
