through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes
nationaux de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est
en général confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l'ISO participent également aux travaux.
L'ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a été
rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso

DRAFT INTERNATIONAL STANDARD ISO/DIS 16217:2018(E)
Cosmetics — Sun protection test methods — Water
resistance — Water immersion procedure
1 Scope
This International Standard describes a procedure of water immersion for the in vivo determination of
water resistance of sunscreen products using a water immersion procedure.
This standard is applicable to products intended to be placed in contact with human skin including
any component able to absorb, reflect or scatter UV rays and which, in addition, are designed to be less
readily removed from the skin by water and/or during water immersion. It shall be read in conjunction
with ISO 24444, Cosmetics — Sun protection test methods — in vivo determination of Sun Protection
Factor (SPF).
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. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 17025:2017, General requirements for the competence of testing and calibration laboratories
ISO 24444, Cosmetics — Sun protection test methods — In vivo determination of the sun protection
factor (SPF)
ISO 18883, Cosmetics — Sun protection test methods — Determination of percentage of water resistance
3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
simulated swim test device
A spa, whirlpool or similar device which is designed for water immersion and which fits the
requirements of this standard as defined in Annex A.
3.2
standardised water
Water for use in the Simulated Swim Test Device shall comply with the requirements of Annex B of this
Standard.
3.3
MEDiui
MEDiui is the individual MED value for the unprotected site.
3.4
MEDipi
MEDipi is the individual MED value for the sunscreen protected site after immersion.
3.5
individual SPFiwr
SPF determined after water immersion step on each subject. SPF iwr= MEDipi protected skin / MEDiui
unprotected skin determined after water immersion.
