ISO 12917-1:2017 specifies manual methods for the calibration of nominally horizontal cylindrical tanks, installed at fixed locations. The methods in this document are applicable to insulated and non-insulated tanks, either when they are above-ground or underground. The methods are applicable to pressurized tanks and to both knuckle-dish-end and flat-end cylindrical tanks as well as elliptical…

ISO 19204:2017 describes in a general way the application of the soil quality TRIAD approach for the site-specific ecological risk assessment of contaminated soils. In detail, it presents in a transparent way three lines of evidence (chemistry, ecotoxicology and ecology) which together allow an efficient, ecologically robust but also practical risk assessment of contaminated soils. This procedure…

IEC 60669-1:2017 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. This part of IEC 60669 applies to manually operated general purpose functional switches, for alternating current (AC…

IEC 60669-1:2017 applies to manually operated general purpose functional switches, for alternating current (AC) only with a rated voltage not exceeding 440 V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals, the rated current is limited to 16 A. This fourth edition…

IEC 60826:2017 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 60826:2017: specifies the loading and strength requirements of overhead lines derived from reliability-based design…

IEC 60826:2017 specifies the loading and strength requirements of overhead lines derived from reliability-based design principles. These requirements apply to lines 45 kV and above, but can also be applied to lines with a lower nominal voltage. This document also provides a framework for the preparation of national standards dealing with overhead transmission lines, using reliability concepts…

ISO 13643-2:2017 defines symbols and terms and provides guidelines for the conduct of tests to give evidences about the turning ability and the yaw containment of surface ships, submarines, and models. It is intended that it be read in conjunction with ISO 13643‑1.

ISO 13643-3:2017 defines symbols and terms and provides guidelines for the conduct of tests to give evidence about the yaw stability and steering of surface ships, submarines, and models. It is meant to be read in conjunction with ISO 13643‑1.

ISO 13643-4:2017 defines symbols and terms and provides guidelines for the conduct of tests to give evidence about the stopping, acceleration, and traversing of surface ships, submarines, and models. It is intended to be read in conjunction with ISO 13643‑1.

ISO 13643-5:2017 defines symbols and terms and provides guidelines for the conduct of tests to give evidence about the manoeuvring ability in the vertical plane of submarines and models. It is intended to be read in conjunction with ISO 13643‑1.
