This European Standard specifies laboratory test procedures to determine the dynamic stiffness of resilient components of track for the purpose of evaluating the environmental noise and vibration performance of the track. This standard is applicable to complete track fastening assemblies and to pad components of fastening systems.It is applicable to specimens of a single rail seat fastener.It is applicable to the measurement of a tangent, dynamic stiffness under a prescribed pre-load and the associated hysteretic damping loss factor. It provides measurement methods and pre-load, excitation and frequency range conditions for application to ground borne and structure borne noise as well as for rolling noise.It provides measurement methods and pre-load, excitation and frequency range conditions for application to ground borne and structure borne noise as well as for rolling noise.It is not applicable to the measurement of the stiffness of pads and fastening assemblies under static or low frequency dynamic loading which is specified in EN 13146-9.

This Part of this European Standard specifies and classifies basic alumino silicate glass products, indicates their chemical composition, their main physical and mechanical characteristics, their dimensional and their minimum quality requirements (in respect of optical and visual faults).This European Standard applies to basic alumino silicate glasses supplied in stock sizes, supplied sizes or in cut sizes for final end use.This European Standard does not apply to final cut sizes having a dimension less than 100 mm or a surface area less than 0,05 m2.

This series of standards applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their components.This part of the series defines the classification levels as well as the requirements for manufacturers of welded railway vehicles and components.

This document specifies methods for measuring overall migration of plastic materials and articles intended to come into contact with foodstuffs by contacting test specimens with vegetable oils at temperatures greater than or equal to 4 °C and up to 175 °C.NOTE Some vegetable oils are not suitable for use below 20 °C.The overall migration from a sample of the plastics is determined as the loss in mass of non-volatile substances expressed:- per unit surface area, or- per kg of food simulant, or- per article;after contact with a food simulant under defined conditions.According to the type of materials or articles, contact with the food simulant is carried out on a single surface (pouch, cell, filling) or by immersion.This document does not cover the interpretation of the results which is expected to account for regulatory requirements.

This document specifies methods for measuring overall migration of plastic materials and articles intended to come into contact with foodstuffs by contacting test specimens with evaporable food simulants at temperatures greater than or equal to 4 °C and not exceeding the reflux temperature.The overall migration from a sample of the plastics is determined as the loss in mass of non-volatile substances expressed:- per unit surface area, or- per kg of food simulant, or- per article;after contact with a food simulant under defined conditions.According to the type of materials or articles, contacting with the food simulant is carried out on a single surface (pouch, cell, filling) or by immersion.This document does not cover the interpretation of the results which is expected to account for regulatory requirements.

This European Standard specifies the general safety and quality requirements and test methods for domestic swimming pools. These requirements and test methods are applicable to inground, aboveground or recessed swimming pool structures, including their installation and means of access.This standard does not apply to:- pools for public use covered by EN 15288-1;- spas for domestic or public use;- paddling pools according to EN 71-8.

This document provides a nomenclature of oral developmental disturbances of teeth and a code for their representation to facilitate data entry and support interoperability at the semantic level.This nomenclature covers the various developmental disturbances of teeth.

This document provides a nomenclature of oral anomalies and a code for their representation to facilitate data entry and support interoperability at the semantic level.This nomenclature covers the various anomalies that can be found in the oral cavity. When needed, information on the localization of the anomaly can be added through the use of other codes such as ISO 3950.

This document specifies requirements and their test methods for tissue punches used with a handpiece in dentistry especially for oral surgical implant procedures such as cutting holes or notches in and removing of gingival tissue. It also specifies the requirements for their marking and labelling.
