This draft European Standard specifies requirements for the safety of children's cot duvets, excluding removable duvet covers, used in the child s sleeping environment (i.e. not under supervision), and designed to provide sufficient warmth when sleeping in a cot or similar product (e.g. bedside sleeper) in which a child is contained. This document specifies requirements for cot duvets suitable for children up to 36 months. Cot duvets with permanent decorative outer fabrics also known as cot quilts or coverlet are also in the scope. NOTE The informative Annex E lists topics of further investigations which might lead to necessary improvement of the safety requirements of children's cot duvets. The requirements for removable cot duvet covers are excluded from this document and are covered in prEN 16779-2 (in preparation). If a part of the children's cot duvet is designed to offer additional function (e.g. play function), in addition of the following requirements, this part will be subjected to safety requirements related to relevant standards (see A.1).
