This document provides a framework for specifying a range of characteristics as well as applicable test methods for polymer modified bitumens, which are suitable for use in the construction and maintenance of roads, airfields and other paved areas, together with information on assessment and verification of constancy of performance. Polymer modified bitumen is defined in EN 12597.

This document describes the performance for characteristics of polymer modified bitumens, as shown in Table 1 and Table 2. It gives information for Declaration of Performance, selection of the grades, characteristics and test methods.

This framework covers the following essential characteristics:

—    consistency at intermediate service temperature;

—    consistency at elevated service temperature;

—    viscoelastic behaviour;

—    cohesion;

—    resistance to flow and deformation;

—    temperature sensitivity;

—    strain recovery;

—    durability of strain recovery;

—    durability of consistency at low service temperature;

—    durability of viscoelastic behaviour.

The characteristics of “adhesion” and “setting ability” are addressed by tests used on either the finished asphalt mixtures or on aggregate-bitumen combinations, i.e. EN 12697‑1, EN 12697‑11, EN 12697‑12, EN 12697‑26 [2 to 5], rather than tests on the bitumen itself.

“Adhesion” is addressed by tests carried out on the finished asphalt mixtures.

“Setting ability” is the return of the polymer modified binder to its normal semi-solid state as it returns to ambient temperature; this is a natural result of the cooling of the hot polymer modified bitumen after application and thus not addressed here.

The nomenclature of polymer modified bitumen comprises the nominal penetration range and the minimum softening point, e.g. PMB 45/80-60.

This international standard provides the accelerated test method to assess effects of the tarnishing of silver and silver alloys used for LED packages due to hydrogen sulphide. Particularly, this test method is intended to give information on silver and silver alloy tarnishing effects to the luminous/radiant flux maintenance of LED packages. Additionally, this test method may give information on electric performances of LED packages due to corrosion of silver and silver alloys.

The object of this test is to determine the influence of atmospheres containing hydrogen sulphide on parts of LED packages made of:

silver or silver alloy;

silver or silver alloy protected with another layer;

other metals covered with silver or silver alloy.

Testing other degradations that may affect luminous/radiant flux maintenance and/or electric performance (e.g. degradation of copper or silicone parts) is not the object of this test.

In all tests, the major criterion of performance will be the change in the luminous/radiant flux and/or electric characteristics (e.g. forward voltage and forward current) caused by sulphide corrosion.

This test may not be suitable as a general corrosion test, i.e. it may not predict the behaviour of flux and/or electric characteristics and connections in industrial atmospheres.

This standard also contains an informative Annex A that gives information to predict luminous/radiant flux degradation due to the silver and silver alloy tarnishing in particular conditions from test results.

This document is applicable to LED packages for lighting applications only if referenced by an IEC SC 34A document.

 

NOTE: To assess effects to the contact resistance for contacts and connections due to corrosion of silver and silver alloy, see IEC 60068-2-43. Because the criterion performance in IEC 60068-2-43 is contact resistance it is not applicable to LED packages to determine effects to the luminous/radiant flux maintenance.

This part of IEC 60384 applies to fixed capacitors for direct current, with metallized electrodes and polyethylene-terephthalate dielectric for use in electronic equipment.

These capacitors may have “self-healing properties” depending on conditions of use. They are primarily intended for applications where the AC component is small with respect to the rated voltage. Two performance grades of capacitors are covered, Grade 1 for long-life application and Grade 2 for general application.

Capacitors for electromagnetic interference suppression and surface mount fixed metallized polyethylene-terephthalate film dielectric DC capacitors are not included, but are covered by IEC 60384-14 and IEC 60384-19 respectively.

The object of this document is to prescribe preferred ratings and characteristics and to select from IEC 60384-1 the appropriate quality assessment procedures, tests and measuring methods, and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification should be of equal or higher performance level, because lower performance levels are not permitted.

This part of IEC 62053 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only.

NOTE 1: For other general requirements, such as safety, dependability etc., see the relevant IEC 62052 or IEC 62059 standards.

This document applies to electricity metering equipment designed to:

measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC;

have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays;

operate with integrated or detached indicating displays, or without an indicating display;

be installed in a specified matching socket or rack;

optionally, provide additional functions other than those for measurement of electrical energy.


They may be used for measuring DC electrical energy, amongst others, in the following application areas:

in EV (electrical vehicle) charging stations or in EV charging infrastructures, if the measurement is placed on the DC side;

in information technology (IT) server farms;

in DC supply points for communication equipment;

in low voltage DC networks for residential or commercial areas, if the measurement is placed on the DC side;

in solar PV (photo voltaic) systems where DC power generation is measured;

in DC supply points for public transport networks (e.g. trolleybus etc.).

 

Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series may be tested for compliance with this document only if such meters and their LPITs are tested together and meet the requirements for directly connected meters.

NOTE 2: Modern electricity meters typically contain additional functions such as measurement of voltage magnitude, current magnitude, power etc.; measurement of power quality parameters; load control functions; delivery, time, test, accounting, recording functions; data communication interfaces and associated data security functions. The relevant standards for these functions may apply in addition to the requirements of this standard. However, the requirements for such functions are outside the scope of this document.

This document does not apply to:

meters for which the voltage between the two poles, where one of the poles is connected to earth, exceeds 1 500 V DC;

meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series of standards) when tested without such transformers;

metering systems comprising multiple devices physically (except of LPITs) remote from one another;

portable meters;

NOTE 3:  Portable meters are meters that are not permanently connected.

meters used in rolling stock, vehicles, ships and airplanes;

laboratory and meter test equipment;

reference standard meters;

data interfaces to the register of the meter;

matching sockets or racks used for installation of electricity metering equipment;

any additional functions provided in electrical energy meters.

This document does not cover measures for detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering).

NOTE 4: Nevertheless, specific tampering detection and prevention requirements, and test methods, as relevant for a particular market are subject to the agreement between the manufacturer and the purchaser.

NOTE 5: Specifying requirements and test methods for fraud detection and prevention would be counterproductive, as such specifications would provide guidance for potential fraudsters.

NOTE 6: There are many methods of tampering with meters reported from various markets; designing meters to detect and prevent all kinds of tampering would lead to unjustified increase in costs of meter design, verification and validation.

NOTE 7: Billing systems, such as, smart metering systems, are capable of detecting irregular consumption patterns and irregular network losses which enable discovery of suspected meter tampering.

NOTE 8: This document does not specify emission requirements, these are specified in IEC 62052-11: 13/1778/CDV, section 9.3.14.

This document specifies a common framework for audit trails for electronic health records (EHR), in terms of audit trigger events and audit data, to keep the complete set of personal health information auditable across information systems and domains.

It is applicable to systems processing personal health information which, complying with ISO 27799, create a secure audit record each time a user accesses, creates, updates, or archives personal health information via the system.

NOTE       Such audit records at minimum uniquely identify the user, uniquely identify the subject of care, identify the function performed by the user (record creation, access, update, etc.), and record the date and time at which the function was performed.

This document covers only actions performed on the EHR, which are governed by the access policy for the domain where the electronic health record resides. It does not deal with any personal health information from the electronic health record, other than identifiers, the audit record only containing links to EHR segments as defined by the governing access policy.

It does not cover the specification and use of audit logs for system management and system security purposes, such as the detection of performance problems, application flaw, or support for a reconstruction of data, which are dealt with by general computer security standards such as ISO/IEC 15408[9].

Annex A gives examples of audit scenarios. Annex B gives an overview of audit log services.

This DIS enables the advancement of interoperability from the data/information exchange paradigm to knowledge sharing at decreasing level of abstraction, starting at IT concept level (semantic coordination) through business domain concept level (agreed service function level cooperation), domain level (cross-domain cooperation) up to individual context (skills-based end-user collaboration). The DIS defines a model and framework for a harmonized representation of existing or intended systems with a specific focus on ICT-supported business systems. The Interoperability and Integration Reference Architecture supports ontology harmonization or knowledge harmonization to enable interoperability between, and integration of, systems, standards and solutions at any level of complexity without the demand for continuously adapting/revising those specifications. The approach can be used for analyzing, designing, integrating, and running any type of systems. For realizing advanced interoperability, flexible, scalable, business-controlled, adaptive, knowledge-based, intelligent health and social ecosystems must follow a systems-oriented, architecture-centric, ontology-based and policy-driven approach.

The languages for representing the different views on systems such as ontology languages like Common Logic (CL) (ISO/IEC 24707) and Web Ontology Language (OWL) – specifically OWL 2 (WWW Consortium), languages for modeling and integrating business processes like Business Process Modeling Language (BPML) (OMG), but also OMG’s Unified Modeling Language (UML, also specified as ISO/IEC 19505) based representation styles for the different ISO/IEC 10746 views are outside the scope of this document.

This document specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This document is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams, ISO 11146‑1 is applicable.

Within this document, the description of laser beams is accomplished by means of the second order moments of the Wigner distribution rather than physical quantities such as beam widths and divergence angles. However these physical quantities are closely related to the second order moments of the Wigner distribution. In ISO/TR 11146‑3, formulae are given to calculate all relevant physical quantities from the measured second order moments.

This document specifies a gravimetric method and a vibroscope method for the determination of the linear density of textile fibres applicable respectively to:

a)    bundles of fibres;

b)    individual fibres.

Useful data can be obtained on man-made fibres and, with less precision, on natural fibres.

The procedures can be applied only to fibres which can be kept straight and, in the case of bundles, parallel, during test preparation. These methods are properly applicable when the fibres are readily freed of crimp. They are not applicable to tapered fibres.

NOTE       The vibroscope method may not be applicable to hollow and flat (ribbon-like) fibres.
