Control and protective devices for gaseous and liquid fuels — Particular requirements — Part 1: Electronic fuel/air ratio control systems, including associated sensors and mechanical actuators
Käsitlusala:
This document specifies safety, design, construction and performance requirements and testing for electronic fuel/air ratio control (FARC) systems. Systems can include sensors, mechanical actuators and motors/blowers that make up the complete system. Systems can be described as:
closed loop fuel/air ratio control systems (ERC), see 3.1.1;
closed loop fuel/air ratio trim systems (ERT), see 3.1.2;
fuel/air ratio supervision systems (ERS), see 3.2.
NOTE 1 Throughout this document, the word “system” means “FARC control and system components”.
These systems are intended for use with burners and appliances that burn gaseous or liquid fuels. This document describes the procedures for evaluating these requirements and specifies information necessary for installation and use.
This document applies to the inherent safety of the system, to the declared operating values, operating times and operating sequences if they are associated with FARC safety and to the testing of FARC systems used in, on or in association with appliances.
NOTE 2 The documents for burners, appliances or processes which use ERC, ERS or ERT can override the requirements of this document.
This document prescribes testing requirements in addition to the relevant standards for integrated devices or components (e.g. actuators) to ensure safe operation of the FARC system.
If no part 2 standards in ISO/TC 161, Controls and protective devices for gaseous and liquid fuels, or IEC/TC 72, Textile machinery and accessories, exist, then IEC 60730-1 is considered.
NOTE 3 Supplemental or modified requirements and tests and evaluations can be needed for ERC, ERS or ERT systems for conformance with relevant burner, appliance or process standards. Conformance of an ERC, ERS or ERT with this document does not imply that such systems or components thereof are acceptable for use on an appliance without supplemental tests of the control system applied to the particular appliance to meet the requirements of the relevant burner, appliance or process standard(s).
This document applies to electronic fuel/air ratio control systems that can be tested independently or as a system or as part of an appliance or as part of a burner.
This document does not cover burner control function like e.g. burner ignition, flame supervision and fuel shutoff.

Photovoltaic power generating systems connection with grid - Testing of power conversion equipment - Part 3: Basic operations
Käsitlusala:
This document specifies test procedures for confirming the basic operational characteristics of power conversion equipment (PCE) for use in photovoltaic (PV) power systems with or without energy storage.
The basic operational characteristics are the capability of the PCE before any limitations due to internal settings are applied to the PCE to meet specific grid support functions or specific behaviours against abnormal changes.
This document covers the testing of following items:
a) Steady state characteristics
Test procedures to confirm operable range of PCE at steady state condition are described. The operable ranges in apparent power, active power, reactive power, power factor, grid voltage and grid frequency shall be confirmed according to the test procedures.
b) Transient-response characteristics
Test procedures to confirm PCE’s response against a change of operational condition are described.
Transient-response characteristics to be confirmed are response behaviours against;
• Active power set point change and reactive power set point change
• Grid voltage change, phase angle change, voltage unbalance and frequency change
This document only considers the changes within normal (continuous) operable ranges. Therefore, the behaviours against abnormal changes and grid support functions are out of the scope and are covered in other parts of this series of International Standards.

Heating systems in buildings - Design of heat pump heating systems

This document specifies design criteria for heating and cooling systems in buildings using electrically driven heat pumps for heating and cooling alone or in combination with other heat generators. The heat pump systems considered in this document (source system/sink system) are listed in Table 1. For cooling purposes, energy source and energy sink can be reversed.
This document also applies to other energy sources such as wastewater, massive absorbers, ice storage systems, as well as heat pump systems using more than one energy source.
This document takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of the heat supply but does not cover the design of these systems. This document covers the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system, the control of the whole system and the aspects dealing with energy source of the system.
Design criteria for reversible heat pump systems for heating and cooling are also included in this document.

Hydraulic machines - Guidelines for dealing with hydro-abrasive erosion in Kaplan, Francis and Pelton turbines
Käsitlusala:
This document gives guidelines for:
a) presenting data on hydro-abrasive erosion rates on several combinations of water quality, operating conditions, component materials, and component properties collected from a variety of hydro sites;
b) developing guidelines for the methods of minimizing hydro-abrasive erosion by modifications to hydraulic design for clean water. These guidelines do not include details such as hydraulic profile shapes which are determined by the hydraulic design experts for a given site;
c) developing guidelines based on “experience data” concerning the relative resistance of materials faced with hydro-abrasive erosion problems;
d) developing guidelines concerning the maintainability of materials with high resistance to hydro-abrasive erosion and hardcoatings;
e) developing guidelines on a recommended approach, which owners could and should take to ensure that specifications communicate the need for particular attention to this aspect of hydraulic design at their sites without establishing criteria which cannot be satisfied because the means are beyond the control of the manufacturers;
f) developing guidelines concerning operation mode of the hydro turbines in water with particle materials to increase the operation life.
It is assumed in this document that the water is not chemically aggressive. Since chemical aggressiveness is dependent upon so many possible chemical compositions, and the materials of the machine, it is beyond the scope of this document to address these issues.
It is assumed in this document that cavitation is not present in the turbine. Cavitation and hydro-abrasive erosion can reinforce each other so that the resulting erosion is larger than the sum of cavitation erosion plus hydro-abrasive erosion. The quantitative relationship of the resulting hydro-abrasive erosion is not known and it is beyond the scope of this document to assess it, except to suggest that special efforts be made in the turbine design phase to minimize cavitation.
Large solids (e.g. stones, wood, ice, metal objects, etc.) traveling with the water can impact turbine components and produce damage. This damage can in turn increase the flow turbulence thereby accelerating wear by both cavitation and hydro-abrasive erosion. Hydro-abrasive erosion resistant coatings can also be damaged locally by impact of large solids. It is beyond the scope of this document to address these issues.
This document focuses mainly on hydroelectric powerplant equipment. Certain portions can also be applicable to other hydraulic machines.

The CE mark of building integrated photovoltaic (BIPV) modules will thus state properties based on both documents as they are both equally applicable.
This document references international standards, technical reports and guidelines. For some mounting categories, in addition, national standards (or regulations) for building products may apply in individual countries, which are not explicitly referenced here and for which harmonized European Standards are not yet available.
The document is addressed to manufacturers, planners, system designers, installers, testing institutes and building authorities.

A SUPS has no rotating parts to perform its functions. The specific design requirements for the components of the power supply system are covered by IEC standards and other standards listed in the normative references.
