This document specifies the dimensions of a mouth finish for stoppers and capsules for glass bottles containing a wine that has a carbonation not exceeding 1,2 g CO2/l, with internal sealing. Two options of finish height are proposed, 14 and 16 mm, the most common one being 16 mm. NOTE Carbonation over 1,2 g CO2/l requires a suitable container and stopper agreed between the glassmaker, the stopper manufacturer, and the packer/filler.

 

This document specifies requirements for an experimental method to prove that representative samples of valve shells and their body ends, made in cast iron, steel or copper alloy materials, are designed to possess the required pressure containing capability, with an adequate margin of safety. This document is not applicable to valves designed on the basis of time dependent strength values (creep) or valves designed for pulsating pressure applications (fatigue). For valves in the scope of the European legislation for pressure equipment, the sole use of an experimental method is only permitted when the maximum allowable pressure at room temperature, PS, multiplied by the DN-number is less than 3 000 bar. This document is used to supplement the tabulation method EN 12516-1:2014+A1:2018, and the calculation method EN 12516-2:2014+A1:2021 without limit.

 

This document specifies requirements for tests, test procedures and acceptance criteria for production testing of industrial valves made of metallic materials. NOTE The specified tests can also be used as type tests or acceptance tests. This document does not apply to: - industrial valves of thermoplastic materials; - safety valves and bursting discs (safety accessories); - sight glass with its frames (component of a pressure equipment). When specified as a normative reference in a valve product or performance standard, this document is to be considered in conjunction with given specific requirements of the valve product or performance standard. Where requirements in a product or performance standard differ from those given in this document, the requirements of the product or performance standard apply.

 

This document establishes general principles for the measurement and evaluation of vibration using measurements made on rotating, non-rotating and non-reciprocating parts of complete machines. It is applicable to measurements of vibration on non rotating parts and to both absolute and relative radial shaft vibration with regard to the monitoring of radial clearances but does not generally apply to axial shaft vibration, unless stated. The general evaluation criteria, which are presented in terms of both vibration magnitude and change of vibration, relate to both operational monitoring and acceptance testing. They have been provided primarily with regard to securing reliable, safe, long-term operation of the machine while minimizing any adverse effects on associated equipment. This document also gives guidance on setting operational limits. The evaluation criteria are only applicable to the vibration produced by the machine itself and not the vibration transmitted to it from outside. This document does not apply to torsional vibration.

 

This document specifies the requirements for closing and locking devices of heavy rail freight wagons including durability, their status indication, maintenance and recycling. Annex A specifies pass-fail criteria for the dimensioning tests. This document is not applicable to closing and locking devices which are used to ensure a pressure difference or to retain liquids/liquid payloads. This document is not applicable to heavy rail freight wagons which are emptied by pressure, nor is it applicable to lose tarpaulins.

 

This document specifies the general requirements for evaluating the vibration of various coupled industrial machine types with operating speeds between 120 r/min and 30 000 r/min when measurements are made in-situ. This document gives guidelines for applying evaluation criteria for measurements taken on non-rotating and rotating parts under normal operating conditions. The guidelines are presented in terms of both steady running vibration values and in terms of changes to vibration magnitude, which can occur in these steady values. This document is applicable to the following machine types: The vibration criteria presented in this document are generally only applicable to fans with power ratings greater than 300 kW or which are not flexibly supported. Classifications can be agreed between the machine manufacturer and the customer using results of previous operational experience (also see ISO 14694). This document is applicable to machinery including a gear unit ISO 20816-9 contains information for special acceptance tests related to gear units. This document is not applicable to the following types of industrial machines: This document is applicable to in-situ broad-band vibration measurements taken on the shafts, bearings, bearing pedestals or housings of machines under steady-state operating conditions within their nominal operating speed range. The requirements relate to both acceptance testing and operational monitoring. The evaluation criteria can be applied to both continuous and non-continuous monitoring situations. This document is applicable to machines which have gears or rolling bearings but does not address the diagnostic evaluation of the condition of those gears or bearings. This document is applicable only for the vibration produced by the machine set itself and not for vibration that is transmitted to the machine set from external sources.

 

This document contains requirements for the design, testing, inspection and marking of serially produced, refillable storage systems intended only for liquid hydrogen for land vehicle operation. These storage systems The scope of this document is limited to fuel storage systems containing fuel cell grade hydrogen according to ISO 14687 type II grade D. The content is mainly focused on heavy duty vehicles for road operation but may also be applied to on-board fuel storage systems for other road vehicles, industrial and other land vehicles with due consideration of appropriate service conditions.
