IEC 61083-2:2013
Hind 157,15 EUR
Instruments and software used for measurement in high-voltage and high-current tests - Part 2: Requirements for software for tests with impulse voltages and currents
IEC 61083-2:2013 applies to software used for evaluation of impulse parameters from recorded impulse voltages and currents. It provides test waveforms and reference values for the software required to meet the measuring uncertainties and procedures specified in IEC 60060-1, IEC 60060-2, IEC 60060-3 and IEC 62475. Hardware with built-in firmware that cannot accept external numerical input data is not covered by this standard. The object of this standard is to establish the tests which are necessary to show that the performance of the software complies with the requirements of the relevant IEC standards, define the terms specifically related to digital processing, specify reference values and the acceptance limits for the reference impulses, specify the requirements for the record of performance and define the methods to assess the contribution of software to the measurement uncertainty. This second edition cancels and replaces the first edition published in 1996 and constitutes a techni

IEC/TR 62725:2013
Hind 231,60 EUR
Analysis of quantification methodologies of greenhouse gas emissions for electrical and electronic products and systems
IEC/TR 62725:2013(E) is intended to provide users with guidance to understand methodologies and to evaluate carbon footprint of products (hereinafter referred to as CFP), by quantifying the greenhouse gases (GHG) emissions (hereinafter referred to as CFP study) for Electrical and Electronic products (hereinafter referred to as EE products) based on life-cycle thinking. It is applicable to any type of EE products, which are new or modified (e.g. reconditioned, upgraded, etc.) and is based on the result of a comparative study on existing methodologies published or under discussion in representative international organizations.

FprEN 12668-3
Tähtaeg 30.06.2013
Non-destructive testing - Characterization and verification of ultrasonic examination equipment - Part 3: Combined equipment
This document describes methods and acceptance criteria for verifying the performance of ultrasonic equipment (i.e. instrument and probe combined as defined in EN 12668-1 and EN 12668-2) by the use of appropriate standard calibration blocks. These methods are not intended to prove the suitability of the equipment for particular applications. The methods described are suitable for the use by operators working under site or shop floor conditions. The methods only apply to pulse echo equipment using A-scan presentation, with gain controls or attenuators calibrated in steps not greater than 2 dB and used essentially in contact testing. These methods are specifically intended for manual testing equipment. For automated testing different tests can be needed to ensure satisfactory performance.

FprEN 61207-6
Tähtaeg 30.06.2013
Expression of Performance of gas analyzers - Part 6: Photometric analyzers
This part of IEC 61207 applies to all aspects of analyzers using photometric techniques for the measurement of concentration of one or more components in a mixture of gases or vapours. It should be used in conjunction with IEC 61207-1. For photometric analyzers utilizing tunable diode laser absorption spectroscopy (TDLAS) for gas measurements, IEC 61207-7 should also be referred to. It applies to analyzers using non-dispersive and dispersive wavelength selection and using absorption, emission, wavelength derivative or scattering techniques. It applies to analyzers which receive either a conditioned or unconditioned sample of gas either under vacuum, at ambient pressure or pressurized. It applies to analyzers which measure gas concentrations directly within the sample gas. The object of this part is: – to specify the terminology and definitions related to the functional performance of gas analyzers, utilizing a photometric analyzer, for the continuous measurement of gas or vapour concentration in a source gas; – to unify methods used in making and verifying statements on the functional performance of such analyzers; – to specify what tests should be performed to determine the functional performance and how such tests should be carried out; – to provide basic documents to support the application of standards of quality assurance ISO 9001, ISO 9002 and ISO 9003.

Tähtaeg 30.06.2013
Non-destructive testing - Characterization and verification of ultrasonic phased array systems - Part 1: Instruments (ISO/DIS 18563-1:2013)
This part of the standard identifies the functional characteristics of a multichannel ultrasonic phased array nstrument, used for phased array probes, and provides methods for their measurement and verification. This standard may partly be applicable to ultrasonic phased array instruments in automated systems but then other tests may be needed to ensure satisfactory performance. When the phased array instrument is a part of an automated system, the acceptance criteria may be modified by agreement between the parties involved. The document gives the extent of the verification and defines acceptance criteria within a frequency range 0,5 MHz to 10 MHz. The evaluation of these characteristics permits a well-defined description of the ultrasonic phased array instrument and comparability of instruments.
