EN 16781:2018 (E) 4 European foreword This document (EN 16781:2018) has been prepared by Technical Committee CEN/TC 248 “Textiles and textile products”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2019, and conflicting national standards shall be withdrawn at the latest by February 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. Following the publication and implementation of this document in CEN member countries, it has been agreed by CEN TC 248 that there should be an 18 month transition period from the date of availability to allow manufacturers to develop and produce garments that conform to the standard. This period is also to allow the supply chain, from manufacturer through to the consumer, to be cleared of non-conforming children's sleep bags for use in a cot. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 16781:2018



EN 16781:2018 (E) 5 Introduction The European Commission Mandate N° M/497, followed by Product and Service safety in the Directorate-General Health and Consumers, under the title “Standardisation mandate to CEN, CENELEC and ETSI on the safety of child-care articles; Cluster 2- risks in the sleeping environment; Mattresses for cots, cot bumpers, suspended beds for children, duvets for children, sleep bags for children”, issued on 2011-10-20 and accepted by CEN BT on 2011-12-20, requested that CEN develop standards or specifications including safety requirements and test methods, warnings and instructions to adult users in order to address the possible hazard posed by these products. The aim of this European Standard is to minimize the main risks posed by products in the sleep environment of babies and young children, such as: — internal asphyxiation (choking); — entrapment; — hyperthermia (overheating); — strangulation; — external asphyxiation (suffocation); — flammability; — injuries due to falls; — injuries due to ingestion of small parts; — injuries due to chemicals. For the development of this document, attention was paid to: — the child’s stages of development (age, height, weight, ability, etc.). Sleep bags were studied in relation to children up to 3 years of age. — the intended or foreseeable use of the product, bearing in mind a child’s behaviour. Such behaviour exposes children to injury in ways that differ from those of adults, making children a particularly vulnerable group in society; — the hazard presented by the product in the circumstances under which the product and the child come into contact with each other. IMPORTANT — In order to comply with the essential safety requirements, this document is hazard based. As this document only deals with a particular textile child-care article, i.e. children's sleep bags, design characteristics have been specified only when necessary in order to introduce inherently safe design. These characteristics have been specified in a manner which allows compliance to be checked by interested parties, from designers to market surveillance authority officers. SIST EN 16781:2018



EN 16781:2018 (E) 6 1 Scope This document specifies requirements for the safety of children's sleep bags which are used in the children's sleeping environment (i.e. not under supervision), and designed to provide sufficient warmth so as to remove the need for additional bedding when sleeping in a cot or similar product (e.g. crib/cradle) in which a child is contained. It is applicable to products for use by younger children based on the ability of the children to not being able to climb out of the cot (approximately under the age of 24 months). NOTE The informative Annex D lists topics of further investigations, which might lead to necessary improvement of the safety requirements of children's sleep bags. This document does not apply to products designed for use during the care of premature children or children of low birthweight or for outdoor use or to products designed to keep a child warm in a pushchair or car seats (e.g. foot muff). If a part of the children's sleep bag is designed to offer additional function (e.g. play function), this part will, in addition to the following requirements, be subjected to safety requirements related to relevant standards (see A.1). 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
