This document specifies requirements for the safety of removable cot duvet covers, used in the child s sleeping environment (i.e. not under supervision), and designed to envelop a cot duvet when sleeping in a cot or similar product (e.g. crib/cradle) in which a child is contained. This document specifies requirements for removable cot duvet covers suitable for children up to 36 months. The requirements for cot duvets are covered in EN 16779-1. Some of the requirements in this document are not suitable for articles used by hospitals when nursing sick children. These include: openings for access for tubing to the patient or monitoring devices to monitor the patient; use of fastenings which may not be durable to industrial laundry processing used by hospitals. If a part of the cot duvet cover is designed to offer additional functions (e.g. play function), in addition to the following requirements, this part will be subjected to safety requirements related to relevant standards (see B.1).
