1 Scope 1.1 The CSA O80 Series of Standards specifies requirements related to the preservation and fire retardance of wood through chemical treatment (pressure and thermal impregnation). The subjects covered include materials and their analysis, pressure and thermal impregnation procedures, and fabrication and installation to put treated wood into service. 1.2 This Standard lists reference…

1 Scope 1.1 This Standard specifies requirements for the design and performance of complete active fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest systems. This Standard is intended for engineers with expertise in designing fall-protection systems. 1.2 This Standard does not specify design or performance requirements for fall-arrest equipment or…

This document specifies communication requirements in support of the Smart Digital Tachograph (SDT) as identified by Regulation 2016/799 of the European Union[23]. The specification covers: —    the physical layer at 5,8 GHz for SDT communications (SDTC); —    the data link layer (DLL) of SDTC; —    the application layer of SDTC; —    SDTC profiles which provide coherent sets of communication…

1 Scope 1.1 Application This Code applies to the installation, inspection, repair, and maintenance of the fuel storage and delivery system installed in powered industrial truck applications and vehicles for use with compressed natural gas (CNG). This includes fuel systems on self-propelled vehicles for the provision of motive power. Federal or provincial regulatory requirements might supersede…
