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…

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.…

IEC 60077-5:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC…

IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1…

This document specifies the maximum external gas leakage rates which are acceptable for equipment used for welding, cutting and allied processes and provides the procedures of measurement. It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant). It does not…
