This document specifies the mounting dimensions required for interchangeability of rod-end spherical eyes of pneumatic cylinders. The rod-end spherical eyes have been designed specifically for use with 1 000 kPa [10 bar[1]] series cylinders manufactured in accordance with ISO 6432 and ISO 15552, but this does not limit their application.
The spherical bearing end eyes are used on piston rods of pneumatic cylinders for mechanically transmitting the cylinder force under oscillatory rotational and tilting movements. The design of the rod-end spherical eyes is based on the maximum forces resulting from the specified internal diameter of the cylinders and pressure according to ISO 6432, ISO 15552 and ISO 21287.
[1] 1 bar = 100 kPa = 105 Pa; 1 Pa = 1 N/m2.
This document specifies a method for determining the longitudinal tensile properties of pipe or pipe/pipe or pipe/fitting assemblies using hydraulic pressure. The method accommodates water-in-water or liquid-in liquid tests or their combinations. The document is applicable to pipes and their assemblies with fused or bonded joints with the same or different MRS or design SDR. The method provides load-displacement curves, from which the following properties are determined., — the longitudinal strengths ( — the percent elongation ( σLY , LB ) — the energy to failure (UT)
This document specifies methods for testing the resistance to sustained longitudinal tensile loading (longitudinal stress-rupture) of uniaxial plastic pipe/pipe or pipe/fitting or fitting/fitting assemblies using hydrostatic pressure at a given temperature. This document is applicable to pipe assemblies with electrofusion or butt fusion joints. The methods accommodate water-in-water, water-in-air, and liquid-in liquid tests. Method A uses no external hoop expansion restraint (specifically designed test piece). Method B uses external hoop expansion restraint (metal end caps or circumferential (ring) clamps). Note 1 The longitudinal (axial) tensile loading by hydrostatic internal pressure is achieved by using means to create axial stress as the maximum principal stress over the hoop stress in the assemblies. The external hoop expansion restraint or specific test piece design is used for this purpose[1,2].
This document establishes a system for the classification of fan efficiency for all fan types driven by motors with an electrical input power of 0,125 kW and above. It applies to driven fans only, but not to the system (finished original equipment manufacturer’s product, for example box fans and roof fans or ventilation system) in which they might be installed. This document, as well as ISO 12759-3, ISO 12759-5 and ISO 12759-6, describe a number of different procedures to classify the efficiency of a fan or to apply a minimum efficiency limit (MEL).
Appendix F shows how procedures described in this document can be used to set MELs.
There is no method described to compare these classifications and MELs.
ISO 6162-1:2012 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to four-screw, split and one-piece flange clamp type tube connectors and hose fittings for use at pressures of 3,5 MPa (35 bar ) to 35 MPa (350 bar). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals.
ISO 6162-1:2012 also recognizes the need to accommodate metric screw fasteners (type 1), as well as to provide a means to use existing inch screw fasteners (type 2).
These connections are intended for application in hydraulic systems on industrial and commercial products where it is desired to avoid the use of threaded connectors.
Surges of pressure higher than the nominal ratings will reduce the ability of the flange connections to retain the hydraulic fluid. This needs to be taken into account in the design of the hydraulic system.
This document establishes the general principles for the design and manufacture of mono or multi-layer rotational moulded polyethylene water storage vertical and horizontal cylindrical tanks. This document is applicable to water storage tanks with a nominal service temperature from 1 °C to 60 °C and does not cover any other nominal service temperature. This document does not apply to the following: — Underground water tanks; — Mobile water tanks.
This document specifies methods for determining whether or not a gas or gas mixture is flammable in air and whether a gas or gas mixture is more or less oxidizing than air under atmospheric conditions.
This document is intended to be used for the classification of gases and gas mixtures including the selection of gas cylinder valve outlets.
This document does not cover the safe preparation of these mixtures under pressure and at temperatures other than ambient.
This document specifies the general terms and definitions relevant to the utilization of thermoplastics materials in a circular economy in pipes, fittings and ancillaries for both pressure and non-pressure piping systems. This document is intended to be used by specification writers in conjunction with CEN/TS 14541-2 [7] when preparing normative documents under the scope of CEN/TC 155.
This document specifies the field of application, the dimensional, the physico-chemical properties and the properties of general hydraulic, mechanical and acoustic design of pipe interrupters with permanent atmospheric vent family D Type C, intended to prevent pollution of potable water by backflow, caused by backsiphoning only. It is applicable to pipe interrupters with permanent atmospheric vent in denominations DN 10 up to DN 20. It covers pipe interrupters with permanent atmospheric vent of PN 10 that are capable of working without modification or adjustment: - at any pressure, up to 1 MPa (10 bar); - with any pressure variation, up to 1 MPa (10 bar); - in permanent duty at a limited temperature of 65 °C and for maximum 1 h at 90 °C. It specifies also the test methods and requirements for verifying their characteristics, the marking and the presentation at delivery. Backflow protection devices integrated in flushing valves are similar to DC and are not covered under this document. The requirements are stated in EN 12541.
This document specifies minimum requirements for the materials, design, construction, prototype testing and routine manufacturing inspections of fully wrapped composite gas cylinders for compressed, liquefied and dissolved gases. NOTE 1 For the purposes of this document, the word “cylinder” includes tubes (seamless transportable pressure receptacles of a water capacity exceeding 150 l and of not more than 3 000 l). This document is applicable to cylinders that comprise a liner of metallic material (welded or seamless) or non-metallic material (or a mixture thereof), reinforced by a wound composite consisting of fibres of glass, carbon or aramid (or a mixture thereof) embedded in a matrix. This document is also applicable to composite cylinders without liners. This document is not applicable to gas cylinders which are partially covered with fibres and commonly called “hoop wrapped” cylinders. For hoop wrapped composite cylinders, see EN 12257. NOTE 2 This document does not address the design, fitting and performance of removable protective sleeves. Where these are fitted, they are considered separately. This document is primarily for compressed, liquefied and dissolved gases other than LPG. NOTE 3 For dedicated LPG cylinders, see EN 14427.
This document specifies the requirements for periodic inspection and testing to verify the integrity of cylinders and tubes to be re-introduced into service for a further period of time. This document is applicable to seamless steel and seamless aluminium-alloy transportable gas cylinders (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l and to seamless steel and seamless aluminium-alloy transportable gas tubes (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity greater than 150 l. It also applies, as far as practical, to cylinders of less than 0,5 l water capacity. This document does not apply to the periodic inspection and maintenance of acetylene cylinders or to the periodic inspection and testing of composite cylinders. NOTE Unless noted by exception, the use of the word "cylinder" in this document refers to both cylinders and tubes.
