Full title and description

ISO 1041:1973 — Essential oils — Determination of freezing point. This entry refers to the 1973 ISO international standard that specifies a laboratory method for determining the freezing (stock) point of essential oils; Russian-language PDF reproductions/translations of the 1973 text are available from several standards resellers and catalogues.

Abstract

This short international standard (1973 edition) defines a reference procedure for measuring the freezing point of essential oils, including sample preparation references and measurement conditions. It replaces the earlier ISO/R 1041 procedure and excludes certain special cases (notably essential oil of rose). The original ISO publication is concise (published December 1973).

General information

• Status: Listed as published and active/valid in multiple standards catalogues and resellers (catalog listings show it as the 1973 ISO publication).
• Publication date: 1 December 1973 (ISO 1973 edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.100.60 — Essential oils (physical property test methods).
• Edition / version: 1973 edition (ISO 1041:1973).
• Number of pages: Typically published as a short technical leaflet (catalog listings indicate 2 pages for the ISO original; alternative national publications (e.g., BSI) may show longer formatted copies).

Scope

Specifies a laboratory procedure for determining the freezing point (stock temperature) of essential oils. The method covers sample preparation and the measurement technique required for a reproducible freezing-point determination; it explicitly excludes certain special cases such as essential oil of rose. The standard is intended for routine quality and specification testing of essential oils.

Key topics and requirements

• Definition of the freezing (stock) point for essential oils and the purpose of the measurement (quality control and specification).
• Required sample preparation and references to related ISO sample/handling methods (normative references include methods such as ISO/R 356 and ISO 212 as applicable to sampling and preparation).
• Apparatus and temperature-control requirements to obtain a reproducible freezing-point reading.
• Test procedure steps for determining the freezing point, including cooling/observation criteria and reporting conventions.
• Exceptions and special cases (not applicable to some oils — e.g., rose oil).

Typical use and users

Used by quality-control laboratories in the fragrance and essential-oil industry, standards bodies referencing essential-oil test methods, research laboratories working on natural-product characterization, and suppliers or purchasers specifying physical property acceptance criteria. National standards organizations and commercial standards resellers also provide the published PDF or translations for laboratory use.

Related standards

Normative and related references include earlier ISO/R 1041 (replaced by ISO 1041:1973), ISO/R 356 (preparation of sample for essential-oil testing) and ISO 212 (sampling of essential oils). National adoptions (e.g., BSI adoptions) or related physical-property methods for essential oils may be cross-referenced in practice.

FAQ

Q: What is this standard?

A: ISO 1041:1973 is an ISO technical standard titled "Essential oils — Determination of freezing point" that describes a laboratory method to determine the freezing (stock) point of essential oils.

Q: What does it cover?

A: It covers equipment, sample preparation references, the stepwise test procedure for observing the freezing point, reporting of results, and notes on special cases (for example, it is not applicable to essential oil of rose).

Q: Who typically uses it?

A: Analytical laboratories, essential-oil producers and buyers, quality-control personnel, standards bodies, and researchers concerned with the physical properties and specification testing of essential oils.

Q: Is it current or superseded?

A: The 1973 edition (ISO 1041:1973) is the published ISO document; several standards catalogues and resellers list it as the published/active 1973 standard. Users should check with their national standards body or the ISO catalogue for the official status or any later revisions or replacements before relying on it for regulatory or contractual requirements.

Q: Is it part of a series?

A: It is associated with other ISO methods for essential oils (sampling and test preparation standards such as ISO/R 356 and ISO 212) and replaced an earlier ISO/R technical report version; it sits within ISO/TC 54 subject area (essential oils).

Q: What are the key keywords?

A: Essential oils; freezing point; stock temperature; ISO 1041; test method; sample preparation; physical properties.
