The main changes with respect to the previous edition are: - The determinations for automatic reclosure together with rigid conductors have been revised. - The influence of mid-span droppers to the span has been included. For vertical cable-connection the displacement and the tensile force onto the lower fixing point may now be calculated. Additional recommendations for foundation loads due to tensile forces have been added. The subclause for determination of the thermal equivalent short-circuits current has been deleted (it is now part of IEC 60909-0). The regulations for thermal effects of electrical equipment have been deleted. The standard has been reorganized and some of the symbols have been changed to follow the conceptual characteristic of international standards.

This part of IEC 60099 provides information, guidance, and recommendations for the selection and application of surge arresters to be used in threephase systems with nominal voltages above 1 kV. It applies to gapless metal-oxide surge arresters as defined in IEC 60099-4, to surge arresters containing both series and parallel gapped structure – rated 52 kV and less as defined in IEC 60099-6 and metal-oxide surge arresters with external series gap for overhead transmission and distribution lines (EGLA) as defined in IEC 60099-8. In Annex J, some aspects regarding the old type of SiC gapped arresters are discussed. Surge arrester residual voltage is a major parameter to which most users have paid a lot of attention to when selecting the type and rating. Typical maximum residual voltages are given in Annex F. It is likely, however, that for some systems, or in some countries, the requirements on system reliability and design are sufficiently uniform, so that the recommendations of the present standard may lead to the definition of narrow ranges of arresters. The user of surge arresters will, in that case, not be required to apply the whole process introduced here to any new installation and the selection of characteristics resulting from prior practice may be continued. Annexes H and I present comparisons and calculations between old line discharge classification and new charge classification.

Heating boilers - Heating boilers with forced draught burners-Part 1: terminology, general requirements,testing and marking

This standard is applicable to heating boilers with burners using fans up to a normal heat output of 1000 kw they are operated either with negative pressure (natural draught boiler) or with positivepressure (pressurized boiler) in the combustion chamber, in accordance with the boiler manufacturer’s instructions. This standard specifies the necessary terminology, the requirements on the materials and testing of them , and marking requirements for heating boilers. Particular requirements for boilers which can be used with open vented systems are contained in prEN 303-4. The requirements of this standard apply to heating boiliers which are tested on an authorized test rig. Boilers in accordance with this standard are designed for the heating of central heating installations in which the heat carrier is water and the maximum alloqable operating temperature of which is restricted to 100 0 c. The maximum allowable operating pressure is 8 bar. For boilers with a built-in or attached water heater (storage or continuous flow heater ) this standard onlyapplies to the parts of the water heater which are necessarlly subject to the operating conditions of the heating boiler ( heating part ). This standard does not apply to gas boilers with atmospheric burners , boilers for solid fuels, oil or gas fired condensation boilers, bollers with oil vaporization burnes and low temperature boilers, for these bollers there are further requirements. NOTE : low temperature boillers are those operating with a (water) variable temperature up to 40 c or less , or those which cannot be set at a temperature higher than 550c .


Heating boilers - Heating boilers with forced draught burners-Part 2: Special requirements for boilers with atomizing oil burners

This European Standard describes the reference washing and dry sieving method used for type testing and in case of dispute, for determination of the particle size distribution of aggregates. For other purposes, in particular factory production control, other methods may be used, provided that an appropriate working relationship with the reference method has been established. It applies to all aggregates, including lightweight aggregates, up to 90 mm nominal size, but excluding filler. NOTE 1 The determination of the grading of fillers is specified in EN 933-10 Assessment of fines — Grading of filler aggregates (air jet sieving).
