Marking and documentation requirements for Photovoltaic Modules
This European Standard describes marking, including nameplate and documentation requirements for non-concentrating photovoltaic modules. This European Standard provides mandatory information that needs to be included in the product documentation or affixed to the product to ensure safe and proper use. Best practices are included in this document giving guidance on additional information, for example module’s performance at different irradiance levels. Markings, including nameplates, are permanently affixed information on the PV modules, which indelibly states the rating and other information as required by the relevant standard for safe use and maintenance. While, documentation information is a technical description separate from the photovoltaic module. This European Standard is based on IEC and EN standards defining marking, nameplate and documentation requirements for PV modules.

Low-voltage electrical installations -- Part 8-2: Smart Low-Voltage Electrical Installations
This part of IEC 60364 provides additional requirements, measures and recommendations for design, erection and verification of all types of low-voltage electrical installation according to Clause 11 of IEC 60364-1:2005 including local production and storage of energy in order to ensure the compatibility with the existing and future ways to deliver the electrical energy to current-using equipment or to the public network by means of local sources. Such electrical installations are equipped with a local Electrical Energy Management System (EEMS) and are designated as Prosumer’s Electrical Installations (PEI). This document also provides requirements for proper behavior and actions of PEI in order to efficiently obtain sustainable and safe operations of it when integrated into smart grids. These requirements and recommendations apply, within the scope of the IEC 60364 series, for new installations and modification of existing installations. NOTE Electrical sources for safety services including associated electrical installations and standby electrical supply systems for a secure continuity of supply, which are operated only occasionally and for short periods (e.g. monthly 1 hour) in parallel with the distribution grid for testing purposes, are outside the scope of this part.

This International standard specifies the requirements and the test methods for the characterization of a large-size parabolic-trough collector This standard covers the determination of optical and thermal performance of parabolic-trough collectors, and the tracking accuracy of the collector one-axis tracking system. This test method is for outdoor testing only. This standard applies to parabolic-trough collectors equipped with the manufacturer-supplied sun tracking mechanism. The testing method in this standard does not apply to any collector under operating conditions where phase-change of the fluid occurs. This standard applies to the whole collector. The different component/ elements (such as the receiver, reflector, tracker, structure) should be tested separately by current testing methods when available.

The purpose of this guide is to establish, in a general way, suitable procedures and tolerances for the installation of hydroelectric turbines and generators. This guide presents a typical assembly. It should be recognized that there are many possible ways to assemble a unit. The size of the machines, design of the machines, layout of the powerhouse and delivery schedule of the components are some of the elements that could result in additional steps, the elimination of some steps and/or assembly sequences. It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it. The guide excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation. The tolerances in this guide have been established upon Best Practices and experience, although it is recognized that other standards are specifying different tolerances. Wherever the guide specifies that documents, drawings or information shall be supplied by a manufacturer (or by manufacturers), each individual manufacturer shall be required to furnish the appropriate information for their own supply only.

This standard provides information for assessing and presenting the acoustic emission characteristics of heat exchangers under stationary operating conditions. This European Standard is applicable to selfstanding forced convection air cooled refrigerant condensers and air cooled liquid coolers "dry coolers" and air coolers. 1.2 Size of source The method specified in EN ISO 3744, EN ISO 3745, EN ISO 3746, EN ISO 9614 1 and EN ISO 9614 2 is applicable to noise sources of any size. Limitations for the size of the source are given in 1.3 of EN ISO 3741:2010, EN ISO 3743 1:2010 and EN ISO 3743 2:2009. 1.3 Object This European Standard offers ways to determine the sound power level of units. Some of them are specifically adapted to provide results with low uncertainties, by using laboratory class or engineering class acoustic methods under highly controlled working conditions. Those results are suitable for certification, labeling and marking purposes. This standard is concerned with objective methods for determining sound power levels LW, expressed in decibels (dB) with reference to a sound power of one picowatt (1 pW), of airborne acoustical noise within the specified frequency range of interest and for prescribed operating conditions of the appliance to be measured: - A-weighted sound power level, LWA; - spectral sound power levels; - emission sound pressure level at workplace, LpA.
