Thyristor valves for thyristor controlled series capacitors (TCSC) - Electrical testing
IEC 62823:2015+A1:2019 defines routine and type tests on thyristor valves used in thyristor controlled series capacitor (TCSC) installations for a.c. power transmission. The tests specified in this standard are based on air insulated valves operating in capacitive boost mode or bypass mode. This consolidated version consists of the first edition (2015) and its amendment 1 (2019). Therefore, no…

Industrial automation systems and integration — Integration of life cycle data for process plants in...
This document defines the principles and methods for conformance testing of software implementations of ISO 15926.
It provides guidance for developing test cases and testing procedures that cover the requirements specified in the ISO 15926 series and in different industry usage contexts, e.g. data exchange, use of reference data libraries and interface services.
This document provides guidance in…
This document specifies conceptual schemas for describing the spatial characteristics of geographic entities, and a set of spatial operations consistent with these schemas. It treats "vector" geometry and topology. It defines standard spatial operations for use in access, query, management, processing and data exchange of geographic information for spatial (geometric and topological)…
Sterilization of health care products — Microbiological methods — Part 2: Tests of sterility perform...
1.1 This document specifies the general criteria for tests of sterility on medical devices that have been exposed to a treatment with the sterilizing agent which has been reduced relative to that anticipated to be used in routine sterilization processing. These tests are intended to be performed when defining, validating or maintaining a sterilization process.
1.2 This document is not…

Photovoltaic (PV) module safety qualification — Part 1: Requirements for construction
1 Scope
This part of IEC 61730 specifies and describes the fundamental construction requirements for
photovoltaic (PV) modules in order to provide safe electrical and mechanical operation.
Specific topics are provided to assess the prevention of electrical shock, fire hazards, and
personal injury due to mechanical and environmental stresses. This part of IEC 61730
pertains to the particular…
Photovoltaic (PV) module safety qualification — Part 2: Requirements for testing
1 Scope
The scope of IEC 61730-1 is also applicable to this part of IEC 61730. While IEC 61730-1
outlines the requirements of construction, this part of the standard lists the tests a PV module
is required to fulfill for safety qualification. IEC 61730-2 is applied for safety qualification only
in conjunction with IEC 61730-1.
The sequence of tests required in this standard may not test for…
