This document specifies a computational method (in line with ISO 17201-4) for estimating the acoustic source data of muzzle blast and explosions on the basis of non-acoustic data for firearms with calibres less than 20 mm and explosions less than 50 g TNT equivalent. This document addresses those cases where no source measurements exist. This document can also be used as an interpolation method between measurements of muzzle blast. Source data are given in terms of spectral angular source energy covering the frequency range from 12,5 Hz to 10 kHz and can be used as data input for sound propagation calculation. This document is not applicable to the prediction of sound levels for the assessment of hearing damage; neither can it be used to predict sound pressure levels nor sound exposure levels at distances where linear acoustics do not apply.

This document provides computational methods for determining the acoustical source level of projectile sound and its one-third octave band spectrum, expressed as the sound exposure level for nominal mid band frequencies from 12,5 Hz to 10 kHz. It also gives a method on how to use this source level to calculate the sound exposure level at a receiver position. Results obtained with the standard can be used as a basis for assessment studies for sound around shooting ranges. Additionally, the data can be used to compare sound emission or immission from different types of ammunition used with the same weapon. The prediction methods apply to outdoor conditions and straight projectile trajectories. Two computational methods are given to determine the acoustical source level: one for streamlined projectile shapes and one for non-streamlined shapes, such as pellets.

This document specifies safety requirements and test methods for children’s bedguards for domestic use intended for use with junior or adult beds. These bedguards, when used in conjunction with a bed/mattress combination, are intended to prevent children aged between 18 months and 4 years from falling out of bed. This document is not applicable to bedguards designed for adult use, or to bedguards which are an integral part of a bed, i.e. a permanent fixture not intended to be detached. If the bedguard has several functions or can be converted into another function, the relevant European standard/s apply to it.

ISO 10833:2017 specifies a method to determine the susceptibility of textile floor coverings to mechanical damage at cut edges. It is applicable to all textile floor coverings both as sheet materials and as tiles.

This document specifies requirements and test methods for protective helmets for use in ski mountaineering. This document is also applicable to protective helmets used in activities with similar hazards, but does not apply to protective helmets used specifically by alpine skiers and snowboarders.

This International Standard specifies a method for determining the strength of the seams of resilient floor coverings when welded in accordance with the manufacturer’s instructions.

This document specifies a method to determine the sensitivity of a textile floor covering for appearance change after water has been spilled and dried on the surface. This change can be: a) a colour change; b) a change in structure; c) migration and concentration of chemicals coming from the product. NOTE A concentration of chemicals on a part of the surface can cause accelerated uneven soiling of textile floor coverings.

This document specifies safety requirements and the corresponding test methods for reclined cradles intended for children from birth up to when they start to stand up and infant swings intended for children from birth up to when they start to try to sit up.This document is also applicable to car seats complying with UN R44 or UN R129 that can be used as reclined cradles according to manufacturer’s instructions. If usage as reclined cradle is not included in the product information or marketing material, car seats are excluded from the scope of this document. This document does not cover reclined cradles or infant swings designed for children with special needs and/or falling under the scope of Regulation (EU) 2017/745 (medical devices). If a reclined cradle or infant swing has several functions or can be converted into another function the relevant European standards apply to it. Swings falling under the scope of EN 71-8 are excluded from the scope of this European Standard. NOTE For the rest of the document, the word “product” will be used when referring at the same time to reclined cradles and infant swings.

This document specifies requirements for the maximum amount, and in some cases, the maximum concentration of certain substances and mixtures used in experimental sets for chemistry and related activities. These substances and mixtures are: - those classified as hazardous by the EC-legislation applying to hazardous substances and hazardous mixtures [1]; - substances and mixtures which in excessive amounts could harm the health of the children using them and which are not classified as hazardous by the above-mentioned legislation; and - any other chemical substance(s) and mixture(s) delivered with the experimental set. This document applies to experimental sets for chemistry and related activities including crystal growing sets, carbon dioxide generating experimental sets and supplementary sets. It also covers sets for chemical experiments within the fields of mineralogy, biology, physics, microscopy and environmental science whenever they contain one or more chemical substances and/or mixtures which are classified as hazardous according to Regulation (EC) No. 1272/2008 [1]. This document also specifies requirements for marking, a contents list, instructions for use, eye protection and for the equipment intended for carrying out the experiments. This document does not apply to combined sets, e.g. a combination of a chemistry set and a crystal growing set. It also does not apply to toys that are covered by EN 71-13 (e.g. cosmetic kits). Requirements for certain other chemical toys are given in EN 71-5. NOTE The terms "substance" and "preparation", are used in the "REACH Regulation", Regulation (EC) No. 1907/2006 [2]. According to the Globally Harmonized System (GHS) of classification and labelling of chemicals, which in the European Union has been enacted by Regulation (EC) No. 1272/2008 (classification, labelling and packaging of substances and mixtures) [1], the timetable for the introduction of GHS is followed. The words "preparation" and "mixture" are considered synonymous; both are a mixture or solution of substances that do not react with each other. The old term "preparation" will be replaced by the new term "mixture" in due course. In this document, only the term "mixture" is used.
