2 DS/ISO København DS projekt: M ICS: Første del af denne publikations betegnelse er: DS/ISO, hvilket betyder, at det er en international standard, der har status som dansk standard Denne publikations overensstemmelse er: IDT med: ISO 12787:2011. DS-publikationen er på engelsk. DS-publikationstyper Dansk Standard udgiver forskellige publikationstyper. Typen på denne publikation fremgår af forsiden. Der kan være tale om: Dansk standard standard, der er udarbejdet på nationalt niveau, eller som er baseret på et andet lands nationale standard, eller standard, der er udarbejdet på internationalt og/eller europæisk niveau, og som har fået status som dansk standard DS-information publikation, der er udarbejdet på nationalt niveau, og som ikke har opnået status som standard, eller publikation, der er udarbejdet på internationalt og/eller europæisk niveau, og som ikke har fået status som standard, fx en teknisk rapport, eller europæisk præstandard DS-håndbog samling af standarder, eventuelt suppleret med informativt materiale DS-hæfte publikation med informativt materiale Til disse publikationstyper kan endvidere udgives tillæg og rettelsesblade DS-publikationsform Publikationstyperne udgives i forskellig form som henholdsvis fuldtekstpublikation (publikationen er trykt i sin helhed) godkendelsesblad (publikationen leveres i kopi med et trykt DS-omslag) elektronisk (publikationen leveres på et elektronisk medie) DS-betegnelse Alle DS-publikationers betegnelse begynder med DS efterfulgt af et eller flere præfikser og et nr., fx DS 383, DS/EN 5414 osv. Hvis der efter nr. er angivet et A eller Cor, betyder det, enten at det er et tillæg eller et rettelsesblad til hovedstandarden, eller at det er indført i hovedstandarden. DS-betegnelse angives på forsiden. Overensstemmelse med anden publikation: Overensstemmelse kan enten være IDT, EQV, NEQ eller MOD IDT: Når publikationen er identisk med en given publikation. EQV: Når publikationen teknisk er i overensstemmelse med en given publikation, men præsentationen er ændret. NEQ: Når publikationen teknisk eller præsentationsmæssigt ikke er i overensstemmelse med en given standard, men udarbejdet på baggrund af denne. MOD: Når publikationen er modificeret i forhold til en given publikation.

6 ISO 12787:2011(E) 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO was prepared by Technical Committee ISO/TC 217, Cosmetics. iv ISO 2011 All rights reserved

7 INTERNATIONAL STANDARD ISO 12787:2011(E) Cosmetics Analytical methods Validation criteria for analytical results using chromatographic techniques 1 Scope This International Standard defines validation criteria with which analytical results obtained from the analysis of cosmetic products should comply in order to give confidence in performance, reliability and quality of the final result. It sets out an analytical approach that can be used by a single laboratory to carry out chromatographic analyses on a given sample, or samples. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 General analyte substance being subjected to analysis bias difference between the expectation of the test results and an accepted reference value recovery ratio between the quantity of analyte found by a particular analytical method compared to the quantity of analyte expected post-extraction spiked matrix standards PoEMS samples taken through the entire extraction procedure and spiked with the analyte of interest at the end of the extraction immediately before, or very close to, detection NOTE PoEMS are also called Matrix-Matched Standards or Fortified Analytical Solutions (FAS) and are used for determination of the bias pre-extraction spiked matrix standards PrEMS samples spiked with the analyte of interest at the beginning of the analytical procedure NOTE PrEMS are also called Spikes or Fortified Analytical Portions (FAP) and are used for calibration and quantification of the target analytes in samples (extraction recovery) matrix effect combined effect of the presence of one or more components of a sample other than the analyte on the measured quantity of the analyte NOTE The matrix effect could increase or decrease the chromatographic peak area for a same analyte concentration.
