Test methods for repair materials for water-leakage cracks in underground concrete structures — Part...
ISO/TS 16774-5:2017 specifies a laboratory test method for evaluating watertightness of water-leakage crack repair materials through permeability testing.
These permeability test procedures follow applied conditions outlined in different national testing parameters and requirements. As such, the results are only intended to provide a comparative performance evaluation of the waterproofing repair…
Test methods for repair materials for water-leakage cracks in underground concrete structures — Part...
ISO/TS 16774-6:2017 specifies a laboratory test method for evaluating the substrate (crack) movement response of water-leakage crack repair materials through permeability testing.
The repair material injected into a test specimen with an artificial crack undergoes simulated movements normally caused by thermal expansion, settlement and vibrations in leakage cracks found in concrete structures…
Bi-directional grid connected power converters - Part 1: General requirements
IEC 62909-1:2017 specifies general aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC-port interfaces on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC. In special cases, a GCPC will have only one DC-port interface, which is connected to a bidirectional energy-storage device. This…
Power systems management and associated information exchange - Data and communications security - Pa...
IEC 62351-9:2017 specifies cryptographic key management, namely how to generate, distribute, revoke, and handle public-key certificates and cryptographic keys to protect digital data and its communication. Included in the scope is the handling of asymmetric keys (e.g. private keys and public-key certificates), as well as symmetric keys for groups (GDOI). This document assumes that other standards…

Plastics — Injection moulding of test specimens of thermoplastic materials — Part 1: General princip...
ISO 294-1:2017 specifies the general principles to be followed when injection moulding test specimens of thermoplastic materials and gives details of mould designs for preparing two types of specimen for use in acquiring reference data, i.e. type A1 and type B1 test specimens as specified in ISO 20753, and provides a basis for establishing reproducible moulding conditions. Its purpose is to…
Flexible display devices - Part 5-3: Visual assessment of image quality and defects
IEC 62715-5-3:2017(E) provides the framework and procedures for performing the visual assessment of flexible display devices.
Visual assessment stipulated in this document is applicable to flexible display modules in the following states:
- initial states and ageing states under standard ambient conditions,
- mechanically or environmentally stressed conditions,
- states after mechanical…
Information technology — Open Systems Interconnection — The Directory — Part 6: Selected attribute t...
ISO/IEC 9594-6:2017 defines a number of attribute types and matching rules which may be found useful across a range of applications of the Directory.
Attribute types and matching rules fall into three categories, as described below.
Some attribute types and matching rules are used by a wide variety of applications or are understood and/or used by the Directory itself.
NOTE 1 - It is recommended…
Information technology — Open Systems Interconnection — The Directory — Part 7: Selected object clas...
ISO/IEC 9594-7:2017 defines a number of object classes and name forms which may be found useful across a range of applications of the Directory. The definition of an object class involves listing a number of attribute types which are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and listing the attributes to be used in…
Information technology — Open Systems Interconnection — The Directory — Part 8: Public-key and attri...
ISO/IEC 9594-8:2017 addresses some of the security requirements in the areas of authentication and other security services through the provision of a set of frameworks upon which full services can be based. Specifically, this Recommendation | International Standard defines frameworks for:
- public-key certificates; and
- attribute certificates.
The public-key certificate framework…
