IEC 60584-1:2013 specifies reference functions and tolerances for letter-designated thermocouples (Types R, S, B, J, T, E, K, N, C and A). Temperatures are expressed in degrees Celsius based on the International Temperature Scale of 1990, ITS-90 (symbol t90), and the EMF (symbol E) is in microvolts. The reference functions are polynomials which express the EMF, E in V, as a function of…

Scope 1.1 This standard applies to newly produced type 2 clothes dryers (see Clause 3) hereinafter referred to as dryers, constructed entirely of new, unused parts and materials: a) for use with natural gas; b) for use with manufactured gas; c) for use with mixed gas; d) for use with propane gas; e) for use with liquefied petroleum gases; and f) for use with LP gas-air mixtures. The construction…

Scope 1.1 This Standard applies to air heaters intended for use on nominal system voltages of 600 V or less and designed to be used in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard applies to permanently connected and cord-connected air heaters for household, commercial, and industrial use in non-hazardous locations. 1.3 The term "air heater"…

Scope 1.1 This Standard describes procedures for determining the occupational noise exposure level of workers (Lex,T) using sampling techniques. Lex,T represents the long-term noise exposure of workers and is calculated from measurements of Leq,t in the workplace. Notes: 1) Noise exposure has been expressed as % dose in the past. However, the use of Leq,t is recommended, as it is more…

1 Scope This International Standard specifies requirements for an event sustainability management system for any type of event or event-related activity, and provides guidance on conforming to those requirements. This International Standard is applicable to any organization that wishes to: - establish, implement, maintain and improve an event sustainability management system; - ensure that it is…

1 Scope This part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different…

1 Scope 1.1 This standard specifies the requirements applicable to holders, bases and connectors intended for solid-state (LED) light engines and arrays for installation in lighting equipment, provided that they employ a configuration not typically found on incandescent or fluorescent light sources. 1.2 This standard does not cover lampholders with screw, bayonet or pin-type bases intended to…

1 Scope 1.1 This standard specifies the requirements applicable to field replaceable light-emitting diode (LED) light engines rated up to 347 volts (nominal) and provided with integral lamp bases of other than the screw, bayonet, or pin type configurations typically found on incandescent or fluorescent light sources. 1.2 This standard does not cover: a) LED devices that are integral…

IEC 61754-6:2013 defines the standard interface dimensions for type MU family of connectors. This second edition cancels and replaces the first edition published in 1997 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:<br /> - addition of standard references;<br /> - revision of…
