1.1 This Standard applies to fuel gas piping systems using corrugated stainless steel tubing (CSST), intended for installation in residential, commercial or industrial buildings, and including the following components as a minimum: a) Corrugated stainless steel tubing (CSST); b) Fittings for connection to the CSST; and c) Striker plates (see Clause 3, Definitions) to protect the installed…

1.1 This Standard specifies essential elements for using chemical processes to sterilize medical devices in health care settings, with the object of achieving an adequate level of sterility assurance and minimizing the risk of injury to health care setting personnel and patients. Note: The term “health care setting” includes, but is not limited to, hospitals, free standing surgical centres,…

1.1 This Standard applies to commercial, industrial, and institutional electric clothes-drying equipment intended to be used by trained or supervised personnel only, in nonhazardous locations in accordance with the Canadian Electrical Code, Part I (CEC) on circuits having a nominal voltage not exceeding 600 V. Note: Wherever practical, for convenience, the term ?appliance? has been used in…

IEC 62439-3:2016 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 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of…

IEC 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of IEC 62439 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: parallel transmission of duplicated information. This third edition cancels and…

IEC 62439-5:2016 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE 802.3) Ethernet technology. This part of the IEC 62439 series specifies a redundancy protocol that is based on the duplication of the network, the redundancy protocol being executed within the end nodes, as opposed to a redundancy protocol built in the switches. Fast error detection is…

IEC 62439-2:2016 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE 802.3) (Ethernet) technology. This part of the IEC 62439 series specifies a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node…

IEC 62591:2016 specifies a wireless communication network in addition to the Type 20 in IEC 61158-3-20, IEC 61158-4-20, IEC 61158-5-20, IEC 61158-6-20 and a Communication Profile CP 9/2 in addition to IEC 61784-1, CPF 9. It specifies the following: - Physical layer service definition and protocol specification, - Data-link layer service and protocol, - Application layer service and protocol…

ISO 21940-12:2016 presents typical configurations of rotors with flexible behaviour in accordance with their characteristics and balancing requirements, describes balancing procedures, specifies methods of assessment of the final state of balance, and establishes guidelines for balance quality criteria. ISO 21940-12:2016 can also serve as a basis for more involved investigations, e.g. when a more…

ISO 16016:2016 specifies the protection notices which serve to prevent the improper use of documents and products whose usage is restricted. With the benefit of a uniform text, protection notices draw attention to the existence of an industrial property right or copyright. Furthermore, they clearly show that the owner of the right claims legal protection to the fullest extent and, in addition to…
