API RP 651

Cathodic Protection of Aboveground Petroleum Storage Tanks, Fourth Edition

Published by: American Petroleum Institute / 2014-09-01
The purpose of this recommended practice (RP) is to present procedures and practices for achieving effective corrosion control on aboveground storage tank bottoms through the use of cathodic protection. This RP contains provisions for the application of cathodic protection to existing and new aboveground storage tanks. Corrosion control methods based on chemical control of the environment or the use of protective coatings are not covered in detail.

When cathodic protection is used for aboveground storage tank applications, it is the intent of this RP to provide information and guidance specific to aboveground metallic storage tanks in hydrocarbon service. Certain practices recommended herein may also be applicable to tanks in other services. It is intended to serve only as a guide to persons interested in cathodic protection. Specific cathodic protection designs are not provided. Such designs should be developed by a person thoroughly familiar with cathodic protection practices for aboveground petroleum storage tanks.

This RP does not designate specific practices for every situation because the varied conditions in which tank bottoms are installed preclude standardization of cathodic protection practices.

IEC 60876-1 Ed. 5.0 b:2014

Fibre optic interconnecting devices and passive components – Fibre optic spatial switches – Part 1: Generic specification

Published by: International Electrotechnical Commission / 2014-08-22 / 70 pages
IEC 60876-1:2014 applies to fibre optic switches possessing all of the following general features:
– they are passive in that they contain no optoelectronic or other transducing elements;
– they have one or more ports for the transmission of optical power and two or more states in which power may be routed or blocked between these ports;
– the ports are optical fibres or fibre optic connectors. This fifth edition cancels and replaces the fourth edition that was published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– addition of definitions for the terms for “normally-on;
– “normally-off” and “crosstalk”;
– addition of a new Annex E. Keywords: fibre optic switches, transmission of optical power, fibre optic connectors
