This European Standard specifies performance requirements (methods and procedures for testing and calculating) for determining the Minimum Efficiency Index (MEI) of rotodynamic glanded water pumps for pumping clean water, including where integrated in other products.
The pump types and sizes covered by this standard are described in the Annex A. These pumps are designed and produced as duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, temperatures between -10 °C and +120 °C and 4" or 6" size for submersible multistage pumps at operating temperatures within a range of 0 °C and 90 °C.
In addition, this standard specifies how the value of the Minimum Efficiency Index (MEI) of a pump size indicated by the manufacturer can be checked by market surveillance.
Even if it is left free to the manufacturer of a pump size how to prove the rated value of the Minimum Efficiency Index (MEI), nevertheless this standard specifies a method to prove that this rated value meets the requirements within the confidence intervals with a sufficiently high probability.

This document gives guidance on the selection and evaluation of compatibility between non-metallic materials for gas cylinders and valves and the gas contents. It is also applicable to tubes, pressure drums and bundles of cylinders. This document covers composite and laminated materials used for gas cylinders. It does not include ceramics, glasses and adhesives. This document considers the influence of the gas in changing the material and mechanical properties (e.g. chemical reaction or change in physical state). The basic properties of the materials, such as mechanical properties required for design purposes (normally available from the materials supplier), are not considered. Other aspects, such as quality of delivered gas, are not considered. The compatibility data given are related to single component gases but can be applicable to gas mixtures. This document does not apply to cryogenic fluids (this is covered in ISO 21010).

This document specifies design, type testing, marking, manufacturing tests and examinations requirements for ball valves used as: closures of refillable transportable gas cylinders, pressure drums and tubes; main valves for cylinder bundles; valves for cargo transport units [e.g. trailers, battery vehicles, multi-element gas containers (MEGCs)]; which convey compressed gases, liquefied gases and dissolved gases. NOTE 1     In this document, the term “valve” is used with the meaning of “ball valve”. This document does not apply to ball valves for: oxidizing gases as defined in ISO 10156; toxic gases (i.e. gases listed in ISO 10298 having an LC50 value ≤ 5 000 ppm acetylene for single gas cylinders, pressure drums and tubes. NOTE 2     The reason for the exclusion of oxidizing gases is that the use of ball valves as closures of high-pressure cylinders for oxidizing gases is known to lead to specific ignition hazards that cannot reasonably be mitigated through the ball valve design or type testing. Safety hazards concern both the ball valve itself and any downstream equipment. NOTE 3     The reason for the exclusion of acetylene for single gas cylinders, pressure drums and tubes is that the risk of an acetylene decomposition cannot reasonably be mitigated through the ball valve design or type testing. This document does not apply to ball valves for liquefied petroleum gas (LPG), cryogenic equipment, portable fire extinguishers and cylinders for breathing apparatus. NOTE 4     Requirements for valves for cryogenic vessels are specified in ISO 21011. NOTE 5     Certain specific requirements for quick-release valves for fixed fire-fighting systems in addition to those that are given in this document are specified in ISO 16003.

This document specifies a method for the evaluation of the buckling load which: a) takes into account a geometric model of the hydraulic cylinder, meaning it does not treat the hydraulic cylinder as an equivalent column, b) can be used for all types of cylinder mounting and rod end connection specified in Table 2, c) includes a factor of safety, k, to be set by the person performing the calculations and reported with the results of the calculations, d) takes into account possible off-axis loading, e) takes into account the weight of the hydraulic cylinder, meaning it does not neglect all transverse loads applied on the hydraulic cylinder, f) can be implemented as a simple computer program, and g) considers the cylinder fully extended. The method specified is based on the elastic buckling theory and is applicable to single and double acting cylinders that conform to ISO 6020 (all parts), ISO 6022 and ISO 10762. If necessary, finite element analyses can be used to verify as well as to determine the buckling load. The method is not developed for thin-walled cylinders, double-rods or plunger cylinders. The method is not developed for internal (rod) buckling. The friction of spherical bearings is not taken into account. NOTE      This method is based mainly on original work by Fred Hoblit[2]. This method has been established in reference to the standard NFPA/T3.6.37[1].

The purpose of this document is to establish, in a general way, suitable procedures for
commissioning and operation of hydraulic machines and associated equipment, and to indicate
how such machines and equipment should be commissioned and operated.
Commissioning and operation of the associated equipment are not described in detail in this
document but is considered in the commissioning and operation procedure as a separate step.
Machines of up to about 15 MW and reference diameters of about 3 m are generally covered
by IEC 62006.
It is understood that a guideline of this type will be binding only if the contracting parties have
agreed upon it.
The guidelines exclude matters of purely commercial interest, except those inextricably
connected with the conduct of commissioning and operation.
The guidelines are not concerned with waterways, gates, drainage pumps, cooling-water
equipment, generators, motor-generators, electrical equipment (e.g. circuit breakers,
transformers) etc., except where they cannot be separated from the hydraulic machinery and
its equipment.
Wherever the guidelines specify that documents, drawings or information are supplied by a
supplier (or by suppliers), each individual supplier should furnish the appropriate information
for its own supply only.

This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with
a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.
NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).
NOTE 2 In this document the unit bar is used, due to its universal use in the field of technical gases. It should,
however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa (1 bar = 105 Pa =
105 N/m2).
This document specifies:
— basic dimensions;
— requirements for alternative designs of the yoke-type valve connections;
— dimensions and positions for the holes and pins for the outlet connections.
It also specifies the dimensions and positions for the holes and pins for the outlet connections for gases
and gas mixtures.

This document specifies requirements for the design, materials, manufacturing and testing of pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than:
- 100 bar when containing gases or liquids in group 1 or 2
- 1000 bar when containing liquids in group 2 only.
and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements, bosses etc.
NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and for their corrosion resistance properties.
NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 5.1-1 and 5.1-2. Service conditions are given in Clause 4.
This document, EN 13445-6, does not include lamellar graphite cast iron grades for ferritic and austenitic grades with, with an elongation after fracture equal or less than 15 % which are explicitly excluded. Requirements for the use of cast irons with an elongation after fracture equal or less than 15 % are given in EN 15776.
