Overview
ISO 3517:2012 specifies characteristics and test methods to assess the quality of neroli essential oil (Citrus aurantium) - traditionally cultivated in Tunisia, Morocco and Egypt. The standard defines physical, chemical and chromatographic criteria to help producers, laboratories and buyers verify authenticity, detect adulteration and ensure consistent product quality.
Key topics and requirements
The standard sets mandatory requirements and reference test methods for neroli essential oil, including:
- Appearance, colour and odour
- Clear mobile liquid; pale yellow to amber with slight blue fluorescence; fresh orange-blossom aroma.
- Physical constants
- Relative density at 20 °C: Tunisia/Morocco 0.863–0.876; Egypt 0.870–0.880.
- Refractive index at 20 °C: Tunisia/Morocco 1.464–1.474; Egypt 1.465–1.472.
- Optical rotation at 20 °C: Tunisia/Morocco +2° to +12°; Egypt +2° to +11°.
- Miscibility and acidity
- Miscibility: ≤ 3.5 volumes of 85% ethanol to dissolve 1 volume of oil.
- Acid value: maximum 2.
- Chromatographic profile (normative)
- Gas chromatography required (ISO 11024). The standard lists representative components with min/max percentages for Tunisia/Morocco and Egypt. Major components include:
- Linalool: 26.0–48.0% (Tunisia/Morocco), 26.0–55.0% (Egypt)
- Linalyl acetate: 1.5–15.0% (Tunisia/Morocco), 3.0–20.0% (Egypt)
- Limonene: 9.0–18.0% (Tunisia/Morocco), 7.0–17.0% (Egypt)
- β-Pinene, geraniol, nerol and others are listed with specific ranges.
- Gas chromatography required (ISO 11024). The standard lists representative components with min/max percentages for Tunisia/Morocco and Egypt. Major components include:
- Chirality
- Enantiomeric limits given (e.g., S-(+)-linalyl acetate < 5%) - analysis per ISO 22972.
- Flashpoint
- Indicative value provided (+61 °C) for safety/transport guidance (informative).
Other procedural details: sampling per ISO 212 (minimum final sample 30 ml), and packaging/labeling per ISO/TR 210 and ISO/TR 211.
Applications and users
ISO 3517:2012 is used by:
- Essential oil producers and distillers in North Africa and exporters to global markets
- Quality control and analytical laboratories performing GC and chiral analyses
- Perfume, cosmetics and flavor houses specifying raw material quality
- Traders, buyers and procurement teams verifying batch conformity and origin
- Regulators, customs and safety officers (flashpoint and labeling guidance)
Practical uses include batch acceptance testing, supplier qualification, adulteration detection, product specification drafting, and safety documentation for transport.

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 3517 was prepared by Technical Committee ISO/TC 54, Essential oils.
This third edition cancels and replaces the second edition (ISO 3517:2002), which has been technically revised.

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 (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de droits
de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de ne pas avoir
identifié de tels droits de propriété et averti de leur existence.
L’ISO 3517 a été élaborée par le comité technique ISO/TC 54, Huiles essentielles.
Cette troisième édition annule et remplace la deuxième édition (ISO 3517:2002), qui a fait l’objet d’une
révision technique.
