AbstractThere are over 80 countries in the world that currently use some kind of energy label for electric household appliances. In Europe, as an example, a lot of appliances are obliged to have an energy label when shown for sale, including online. Energy labels give relevant information to the consumers to help them make an environmentally beneficial choice when buying a new appliance. However, the desire for an energy efficient appliance does not outweigh the wish for good performance. Therefore, some energy labels provide information about the performance of the appliance based on international performance measurement standards (hereafter: “international standards”). Indeed, within the one appliance, increased performance can often mean increased energy consumption, so a balance between these parameters needs to be made by product designers and users. Unlike measurements that are traceable to Systeme Internationale units through metrological traceability chains, there is no natural reference data for performance measurements. Therefore, some international standards use a reference machine to relate their testing results to. The comparison of test and reference machine eliminates variances, for example, due to the auxiliary materials used and the influence of manual preparation or assessment methods. Three international standards that are currently using reference machines are examined closely in this paper. It is assessed how the reference machines and their testing results are treated, whether the reference machines are comparable with their corresponding test machines and if the use of a reference machine can be considered beneficial for the testing procedure. Additionally, three key questions are developed that will indicate whether 13 other international standards for electric household appliances could also benefit from using a reference machine. The paper concludes with six recommendations for standardisation groups and energy policymakers that will help with deciding whether a reference machine should be implemented.

The article analyses critera applying to the choice of energy efficient high quality light sources and luminaires, which are used in Russian domestic and international practice. It is found that national standards GOST P 54993–2012 and GOST P 54992– 2012 contain outdated criteria for determining indices and classes of energy efficiency of light sources and luminaires. They are taken from the 1998 EU Directive #98/11/EU “Electric lamps”, in which LED light sources and discharge lamps of high intensity were not included. A new Regulation of the European Union #874/2012/EU on energy labelling of electric lamps and luminaires, in which these light sources are taken into consideration, contains a new technique of determining classes of energy efficiency and new, higher classes are added. The article has carried out a comparison of calculations of the energy efficiency classes in accordance with GOST P 54993 and with Regulation #874/2012/EU, and it is found out that a calculation using GOST P 54993 gives underrated energy efficiency classes. This can lead to interdiction of export for certain light sources and luminaires, can discredit Russian domestic manufacturer light sources and does not correspond to the rules of the World Trade Organization (WTO).

Abstract NIKROTHAL TE is a member of the Nikrothal family of alloys, which are one of two main types of electric-resistance alloys. Nickel-chromium (80Ni-20Cr, for example), developed around the turn of the century, was used as heating-element material in industrial furnaces and electric household appliances. Nikrothal alloys offer advantages in heating-element applications requiring very good mechanical properties in the hot state. This alloy is an attractive alternative to Nikrothal Alloys 40, 60, 70, and 80 (see Alloy Digest Ni-529, September 1997). This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming. Filing Code: Ni-710. Producer or source: Sandvik Heating Technology.
