Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
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 November 2023, and conflicting national standards
shall be withdrawn at the latest by November 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of

Introduction
This document prescribes the minimum standards of design and performance for rotorcraft constant
wear lifejackets, used to reduce the risks of drowning following evacuation or escape from a rotorcraft.
Lifejackets are designed to support the user in water, keep the head above the water, protect the
airways from wave splash and provide some stability in the face-up position. Depending upon the
conditions of use a lifejacket may turn the user from a face-down to a face-up position in the water.
Lifejackets are also equipped with items intended to aid in the location of a survivor in the water. These
include a survivor locator light, whistle and retroreflective material.
The document aims to ensure that the equipment user is able to carry out the necessary emergency
procedures whilst being provided with an appropriate level of protection under foreseeable conditions
of use. It aims to ensure that the equipment presents a minimal hazard in relation to escape from the
rotorcraft, and that the equipment has no detrimental effect on the health and safety of the user or on
the performance of other equipment. There is also a need to ensure that the lifejacket does not prevent
or hinder crew members from carrying out all normal operating procedures and allows them to access
all flight controls.
This document is applicable to all rotorcraft. Rotorcraft include helicopters, tilt rotor/wing and
gyroplanes. For the purpose of this document the term helicopter is used generically hereinafter.
1 Scope
This document specifies requirements for constant wear lifejackets for use by helicopter crew members
and passengers in the event of a ditching or water impact, to ensure minimum levels of performance. It
only applies to constant wear lifejackets for use by adults and that are intended to be manually inflated
after leaving the helicopter.
Helicopter constant wear lifejackets are sometimes designed to be worn with or without a helicopter
immersion suit and/or emergency breathing system.
