1 Scope This document is intended especially to ensure the gas-specific assembly, mechanical resistance, flow, leakage and pressure drop of terminal units and to prevent their interchange between different gases and services and applies to terminal units: a) intended for use in medical gas pipeline systems in accordance with ISO 7396-1; b) used as pressure outlets on pressure regulators in…

1 Scope 1.1 This Standard applies to portable type gas water heaters (herein after referred to as appliance or water heater) for use with propane, butane, or liquefied petroleum gases and mixtures thereof having: a) a regulated pressure; b) a non-regulated pressure. 1.2 Portable type water heaters and components employing materials or having forms of construction differing from those…

1 Scope 1.1 This Standard applies to a complete cablebus system (termination to termination) and associated fittings rated at not more than 46 kV ac or dc, and intended for use in accordance with NFPA 70 (NEC), CSA C22.1 (CE Code, Part I), and CAN/CSA-C22.2 No. 0. These requirements do not apply to metal enclosed busways, as covered by CSA C22.2 No. 201 and CSA C22.2 No. 27/UL 857. 1.2 For…

Standard contains three test options, two types of assessments and, for attached zones, two pressure boundary setups. The test options are the multi-point test, the two-point test and the single-point test. The types of assessments are as-operated and closed-up. The pressure boundary set-ups are guarded and unguarded. Each test can be used to determine the airtightness characteristics…

1 Scope 1.1 This Standard applies to the design, installation, operation, maintenance, and testing of emergency generators and associated equipment for providing an emergency electrical power supply to electrical loads a) in buildings and facilities when the normal power supply fails and an emergency electrical power supply is required by the National Building Code of Canada (NBCC); and b)…

1 Scope This document gives the safety requirements and measures to reduce risks related to woodworking machines arising during operation, adjustment, maintenance, transport, assembly, dismantling, disabling and scrapping and which are common to machines used in the woodworking industry. It is applicable to woodworking, stationary and displaceable machines when they are used as intended and…

IEC 60335-2-110:2013+A1:2019 deals with the safety of microwave appliances intended for commercial use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. Appliances covered by this standard incorporate an open-ended applicator (as example an overview is given in Figure 103) for treatment of the load.…

This document specifies liquefied natural gas (LNG) refuelling nozzles and receptacles constructed entirely of new and unused parts and materials for road vehicles powered by LNG. An LNG refuelling connector consists of, as applicable, the receptacle and the nozzle. This document is applicable only to such devices designed for a working pressure of 1,8 MPa to those using LNG as vehicle fuel and…
