Classes A1a and B1a porcelain (as defined in ISO 13006) are now manufactured in much larger formats than previously available and are increasingly being used as an external cladding material for buildings. Classes A1b, A11a, and AIIb extruded ceramics (as defined in ISO 13006) are not covered by the scope of this document. These materials, when specifically developed for external façade…

IEC 62146-2:2023 is applicable to TRV capacitors used on high-voltage alternating current circuit-breakers with rated voltages above 100 kV with 50 Hz or 60 Hz. TRV capacitors are installed phase to earth, either in parallel to the bushing on dead tank circuit-breakers, or immersed inside the circuit-breaker, or freestanding close to the circuit-breaker. Their function is to limit the transient…

IEC 62146-2:2023 s’applique aux condensateurs TTR utilisés sur les disjoncteurs à courant alternatif haute tension dont les tensions assignées sont supérieures à 100 kV à 50 Hz ou 60 Hz. Les condensateurs TTR à neutre reliés à la terre sont installés soit parallèlement à la traversée sur les disjoncteurs à cuve mise à la terre, soit immergés à l’intérieur du disjoncteur, soit de façon autonome à…

Scope This National Standard of Canada assesses the combustion resistance of mattresses when in contact with a lighted cigarette. This standard covers the resistance of mattresses to ignition only by a burning cigarette and does not relate to their resistance to any other source of ignition or fire conditions. The testing and evaluation of a product against this standard may require the use of…

Scope This National Standard of Canada determines the flame spread properties of a textile product when a specimen is supported at an angle of 45° and a flame is applied to its surface for 1 s. It also describes the dry cleaning and laundering procedures for removing non-permanent flame-retardant treatments applied to textile products. The testing and evaluation of a product against this method…

1 Scope This document gives the safety requirements and measures for stationary and displaceable combined woodworking machines, having at least two separately usable working units and with manual loading and unloading of the workpiece, hereinafter referred to as “machines”. The integrated working units can be of these types only: — a sawing unit; — a moulding unit; — a planing unit. The…

1 Scope 1.1 General This Standard details mechanical, physical, and electrical requirements for a newly manufactured appliance that compresses natural gas for vehicles and dispenses directly into a) the vehicle natural gas fuel storage system, referred to as a vehicle fuelling appliance (VFA); or b) the vehicle’s activated carbon adsorbents-based adsorbed natural gas (ANG) fuel storage…

1 Scope This document establishes a systematic description of the concepts in the field of biometrics pertaining to recognition of human beings. This document also reconciles variant terms in use in pre-existing International Standards on biometrics against the preferred terms, thereby clarifying the use of terms in this field. This document does not cover concepts (represented by terms)…
