A new report by the IEA 4E Solid State Lighting Annex provides a look across the body of literature on lifetime definitions for LEDs and LED products. The reports looks at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test […]
The final report from the IEA 4E Solid State Lighting Annex’s 2017 Interlaboratory comparison (IC 2017). This comparison had 36 participating laboratories from 19 countries with a total of 42 goniophotometric instruments, the largest interlaboratory comparison of such equipment ever undertaken. This comparison investigated the level of agreement in measurements of SSL products by various […]
This controls validation method aims to provide a uniform method of test which will validate native control operation and performance criteria for residential air conditioners and heat pumps with variable speed compressors. This method is intended to be used as a confirmation against regulatory tests in which modulating component(s) are overridden.
This research aims to develop an internationally applicable load-based test method for variable capacity ACs and HPs and has 4 Phases. This report discusses the findings of Phase 2 (Investigative Testing of Key Issues), as well as the research team’s recommendations for Phase 3 work.
A summary of the literature on lifetime definitions for LEDs and LED products, including a look at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test method can best estimate the lifetime of LED lighting products and the report thus addresses a key issue for regulators and industry interested in deployment of LED technologies
Air conditioner (AC) / Heat Pumps (HP) Test Methods Project 2.0 – Phase 1 Findings Summary
Public review draft of the updated Quality and Performance Requirements for LED Lighting Products released 25 November 2020, for comment by 25 January 2021.
This document identifies existing test standards for selected advanced motor technologies and discusses opportunities for potential test procedure harmonization for each categories of equipment analysed.
The current report covers the results, the key findings of the tests in phase 1 of Round Robin program for Converter Losses (RR’C) between December 2017 and October 2018 and the first set of recommendations for amending IEC 61800-9-2, edition 1
This report is a comparative review of test procedures and efficiency metrics for room air conditioners across six countries, as well as the ISO standard. The findings of this report are intended to inform the efforts of policy makers to evaluate where greater consistency between test methods and metrics may be beneficial.
This paper examines elements of existing test procedures that address network standby in some way. This includes horizontal test procedures that cover standby and network standby for a wide range of products, as well as product-specific procedures where network functionality is a common or essential feature of the product
This Policy Brief is based on studies by the IEA 4E Technology Collaboration Programme (4E TCP) into energy efficiency policy measures for pumps, fans and compressors, and the
This Policy Guideline proposes policy options for the inter-national alignment of technical standards and minimum energy performance standards (MEPS) for pump, fan and compressor Motor Driven
This document describes the technical protocol used by the participating laboratories as well as by Nucleus Laboratories.
The objective of this task is to promote the use of the Commission Internationale de l’Eclairage (CIE) International Standard CIE S 025/E:2015 for light emitting diode (LED) based lighting products
This document summarises the first part of an investigation into policy options for harmonising standards and regulations for Motor Driven Units (MDUs), focusing on pumps, fans and compressors. Part 1 describes existing standards and regulations for MDUs in economies that account for 85% of global motor system electricity use
This Policy Guideline investigates policy options for harmonising standards and regulations for Motor Driven Units (MDUs) in two parts. This report (Part 1) describes existing standards and regulations
This briefing summarises the key findings and recommendations of the EMSA report: Policy Guidelines for Electric Motor Systems. Best practice for policies and programmes for electric motor systems
This report presents an overview of published life-cycle assessments (LCA) of lighting equipment, answering questions on the basis of current research. The LCA methodology is used to assess the
