Instrument transformers - Part 102: Ferroresonance oscillations in substations with inductive voltag...
IEC/TR 61869-102:2014(E) provides technical information for understanding the undesirable phenomenon of ferroresonance oscillations in medium voltage and high voltage networks in connection with inductive voltage transformers. Ferroresonance can cause considerable damage to voltage transformers and other equipment. Ferroresonance oscillations may also occur with other non-linear inductive…
Petroleum and natural gas industries — Steel pipes for use as casing or tubing for wells
ISO 11960:2014 specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of ISO 11960:2014. The requirements that define different levels of standard technical requirements…

ISO/TR 4191:2014 gives recommended practices for installation of unplasticized poly(vinyl chloride) (PVC-U) and oriented unplasticized poly(vinyl chloride) (PVC-O) pipes, fittings, valves, and ancillaries when used in piping systems conveying water under pressure.
The recommendations are intended to give practical guidance of design and installation of piping systems incorporating pipes, fittings…
Corrosion des métaux et alliages — Méthode d'essai pour la corrosion des matériaux par des mesu...
L'ISO/TR 16208:2014 décrit les principes fondamentaux de la spectroscopie d'impédance électrochimique (SIE), en se concentrant spécifiquement sur la corrosion des matériaux métalliques. Il traite également de la façon d'utiliser l'appareillage électrochimique, de monter et connecter les instruments électriques, de présenter les données mesurées et d'analyser les résultats…
Corrosion of metals and alloys — Test method for corrosion of materials by electrochemical impedance...
ISO/TR 16208:2014 describes basic principles of electrochemical impedance spectroscopy (EIS), specially focusing on the corrosion of metallic materials. It also deals with how to use electrochemical apparatus, set up and connect electrical instruments, present measured data, and analyse results. However, a more detailed description of this methodology can be found in ISO 16773-1 and ISO 16773-2.
