Small craft - Windows, portlights, hatches, deadlights and doors - Strength and watertightness requirements (ISO 12216:2020)

Small craft - Windows, portlights, hatches, deadlights and doors - Strength and watertightness requirements (ISO 12216:2020)
This document specifies technical requirements and test methods for windows, portlights, hatches, deadlights and doors on small craft with a length of hull, LH, as defined in ISO 8666:2016, of up to 24 m. It takes into account the type of craft, its design category, and the location of the appliance. The appliances considered in this document are only those that are critical for the craft's watertightness. Openings and non-opening devices fitted below area I (see 3.5.2) are excluded from the scope of this document.

Water-tube boilers and auxiliary installations - Part 3: Design and calculation for pressure parts of the boiler
This document specifies the requirements for the design and calculation of water-tube boilers as defined in EN 12952-1. The purpose of this document is to ensure that the hazards associated with water-tube boilers are reduced to a minimum by the proper application of the design according to this part of EN 12952.

Safety and control devices for gas burners and gas burning appliances - Part 1: Pressure regulators for inlet pressures up to and including 50 kPa
EN 13611:2019, Clause 1 applies with the following modification and addition: Modification: The 1st paragraph of EN 13611:2019, Clause 1 is replaced by: This document specifies the safety, design, construction, and performance requirements and testing for pressure regulators and pneumatic gas/air ratio pressure regulators (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulators) for burners and appliances burning one or more gaseous fuels, hereafter referred to as “pressure regulators”. This document is applicable to pressure regulators with declared maximum inlet pressures up to and including 50 kPa and of nominal connection sizes up to and including DN 250. Addition: This document is applicable to: - pressure regulators which use auxiliary energy; - pneumatic gas/air ratio pressure regulators, which function by controlling a gas outlet pressure in response to an air signal pressure, air signal differential pressure, and/or to a furnace pressure signal (zero pressure regulators are included as a special type of pneumatic gas/air ratio p

Automatic shut-off valves for gas burners and gas appliances
EN 13611:2019, Clause 1 applies with the following modification and addition: Modification: The 1st paragraph of EN 13611:2019, Clause 1 is replaced by: This document specifies the safety, design, construction, and performance requirements and testing for automatic shut-off valves for burners and appliances burning one or more gaseous fuels, hereafter referred to as “valves”. This document is applicable to valves with declared maximum inlet pressures up to and including 500 kPa and of nominal connection sizes up to and including DN 250. Addition: This document is applicable to: - electrically actuated valves; - valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy; - valves where the flow rate is controlled by external electrical signals, either in discrete steps or proportional to the applied signal; - valves fitted with closed position indicator switches. An assessment method for valve designs is given by this document. The 4th paragraph of EN 136

Mechanical thermostats for gas-burning appliances
EN 13611:2019, Clause 1 applies with the following modification and addition: Modification: The 1st paragraph of EN 13611:2019, Clause 1 is replaced by: This document specifies the safety, design, construction, and performance requirements and testing for mechanical thermostats intended for use with gas appliances and similar use, hereafter referred to as “thermostats”. This document is applicable to thermostats with declared maximum inlet pressures up to and including 50 kPa and of nominal connection sizes up to and including DN 50 for use with one or more fuel gases. Addition: This document is applicable to thermostats controlling the gas flow directly or indirectly through an integral gas valve. This document applies to thermostats used with gas appliances which are not installed in the open air. Thermostats dealt with in this document are intended for control functions. This document is not applicable to: a) controls which use auxiliary energy (e.g. electrical energy supplied externally); b) an assessment of the control regarding Performance Level (PL) and Safety Integrity Level
