that has a Reid vapour pressure exceeding 276 kPa absolute at 38° C; ( gaz de pétrole liquéfié ) local steering gear control system [Repealed, SOR/2021-135, s. 65] machinery spaces means machinery spaces of category A and all other spaces containing propelling machinery, steering gears, boilers, steam and internal combustion engines, generators and major electrical machinery, oil filling stations, refrigerating, stabilizing, ventilation and air-conditioning machinery, and similar spaces, and trunks to the spaces; ( tranche des machines ) machinery spaces of category A means (a) spaces that contain (i) internal combustion-type machinery used for main propulsion or, where the aggregate of total power output is not less than 373 kW, for purposes other than main propulsion, (ii) an oil-fired boiler, or (iii) a fuel oil unit, and (b) trunks to spaces referred to in paragraph (a); ( tranche des machines de catégorie A ) main steering gear means the main steering gear power unit and actuator by which torque is applied to the rudder stock for the purposes of effecting movement of the rudder to steer a ship; ( appareil à gouverner principal ) major repairs means repairs or alterations to machinery that substantially alter the capacity, size or type of the machinery; ( réparations majeures ) material test certificate means a certificate referred to in section 10; ( certificat d’essai de matériau ) periodic general inspection [Repealed, SOR/2021-135, s. 65] periodic special inspection [Repealed, SOR/2021-135, s. 65] pressure vessel [Repealed, SOR/2021-135, s. 65] remote steering gear control system means the system by which required rudder movements are transmitted to the steering gear power unit controls from the bridge or another location in a ship, excluding the steering gear compartment; ( système de commande à distance de l’appareil à gouverner ) rudder actuator means a unit transmitting torque to a rudder stock (a) through an externally connected tiller, quadrant or similar component, or (b) directly through an integrally housed vane or similar component; ( actionneur de gouvernail ) rules or codes means rules, regulations or codes relating to the construction, installation and inspection of marine machinery, issued by an approved classification society; ( règles ou codes ) shipside door-operating mechanism [Repealed, SOR/2021-135, s. 65] steering gear power unit means (a) in the case of an electric steering gear, an electric motor and its associated electrical arrangements, (b) in the case of an electro-hydraulic steering gear, an electric motor, and its associated electrical arrangements and the connected hydraulic pump, and (c) in the case of a hydraulic steering gear, the driving engine and connected hydraulic pump; ( groupe moteur d’appareil à gouverner ) test pressure means the maximum pressure to which the fluid in a component or system may be subjected during inspection; ( pression d’essai ) unfired pressure vessel means a container subjected to internal or external pressure, where the pressure is produced without the application of heat from an external source or by the application of heat from an indirect source or by any combination thereof, and includes condensers, evaporators, air receivers, hydro-pneumatic tanks, hydraulic accumulators, heat exchangers and similar components, but does not include cooling or heating spaces of engines, pumps, compressors, piping and similar components; ( récipient sous pression non chauffé ) windlass means the machinery and arrangements principally employed in the lowering and raising of the anchors of a ship, but does not include the anchors and cables. ( guindeau ) (2) The units of measurement used in these Regulations are as defined in the Metric Practice Guide published by the Canadian Standards Association. (3) Unless specifically stated otherwise, all prescribed pressures are gauge pressures. SOR/2002-428, s. 1 SOR/2021-135, s. 65
