Published By Publication Date Number of Pages
JIS 2008-11-25 54
]]> This Japanese Industrial Standard specifies the design, manufacturing and inspection methods of the expansion joint intended to be used to absorb the expansion and contraction generated on the heat exchanger, the container with jacket and the like by the temperature change, etc.

When the application of the design method specified in Annex 10 JIS B 8265 to the pressure vessel is allowed, it is applicable.

NOTE: Some figures are block diagrams to show the function only.

Published By Publication Date Number of Pages
IEC 2018-05-14 74
]]> IEC 60744:2018 provides requirements and recommendations for the design, construction and test of safety logic assemblies used in safety systems to perform category A safety functions (in accordance with IEC 61226). Safety logic assemblies include logic such as the hardwired logic assembly interfacing computer-based systems to switchgear, actuators or contactors to provide trip or engineered safety feature actuations. Safety logic assemblies are significant parts of a safety system and may include voting logic between redundant channels. This document provides a general description of safety logic assemblies for safety actuators control. The principles to meet dependability objectives are presented. The main features relating to the design requirements are described and explained.
This new edition includes the following significant technical changes with respect to the previous edition:
a) update of the references to standards published or revised since the issue of the first edition of the current standard, including IEC 61513 and IEC 61226;
b) additional requirements for operational and maintenance bypass use; requirements of voting logic; and others.
