Full title and description
St IEC 61099-2010 — Insulating liquids — Specifications for unused synthetic organic esters for electrical purposes. This International Standard specifies requirements, physical and chemical characteristics, and test methods for unused synthetic organic esters intended for use as insulating and heat‑transfer liquids in transformers, switchgear and similar electrical equipment.
Abstract
IEC 61099:2010 (Edition 2.0) updates and consolidates specifications and test methods for unused synthetic organic esters used as insulating liquids, covering sampling, required properties, limits and conformity tests to ensure suitability for application in transformers, switchgear and related apparatus.

- Publisher: International Electrotechnical Commission (IEC).
- ICS / categories: 29.040.99 (Other insulating fluids).

Scope
IEC 61099:2010 applies to unused synthetic organic esters delivered to an agreed point and time of delivery and intended for use as insulating and/or heat‑transfer liquids in transformers, switchgear and similar electrical equipment. The standard specifies required characteristics, test methods, sampling and criteria for conformity; it does not cover in‑service maintenance of esters (see related maintenance guidance in IEC 61203).
Key topics and requirements
- Definition and classification of unused synthetic organic esters intended for electrical applications.
- Mandatory and informative test methods (physico‑chemical tests such as density, viscosity, flash point, water content, neutralization value, dielectric strength and dissipation factor).
- Specification limits and acceptance criteria for new (unused) ester batches.
- Sampling, packaging and labelling requirements at delivery.
- Guidance on storage, handling and transport of unused esters prior to filling equipment.
Typical use and users
This standard is used by transformer and switchgear manufacturers, utilities, procurement/specification engineers, independent testing laboratories and quality/acceptance personnel who specify, buy, test or certify unused synthetic organic esters for electrical equipment. It informs purchasing specifications, type approvals and factory acceptance testing.
Related standards
Standards and guides commonly referenced with IEC 61099 include IEC 61203 (guidance for maintenance and in‑service management of synthetic organic esters), and regional/adopted versions EN/BS/EVS equivalents of IEC 61099. Other companion standards on insulating liquids and transformer maintenance (for example IEC 60599, IEC 60422 and national adoptions) are also relevant depending on application.

FAQ
Q: What is this standard?
A: IEC 61099:2010 is the International Standard that specifies requirements and test methods for unused synthetic organic esters used as insulating and heat‑transfer liquids in electrical equipment.
Q: What does it cover?
A: It covers definitions, required physical and chemical characteristics, sampling, testing procedures, acceptance limits, packaging and labelling for unused synthetic organic esters destined for transformers, switchgear and similar apparatus. It does not replace maintenance guidance for esters already in service.
Q: Who typically uses it?
A: Equipment manufacturers, utilities, procurement/specification engineers, testing laboratories and conformity/quality personnel who need to specify, test or accept unused synthetic organic esters.
Q: Is it current or superseded?
A: IEC 61099:2010 is the second edition published 31 August 2010 and is the current base publication for this subject (previous edition IEC 61099:1992 was withdrawn on publication of the 2010 edition). The document lifecycle and national adoptions (EN/EVS/BS) reflect that the 2010 edition is the active version. Users should check their national standards body for any later revisions or national supplements.
Q: Is it part of a series?
A: Yes — IEC 61099 is part of the family of standards covering insulating liquids and fluids for electrotechnical applications maintained by IEC TC 10; related guidance and maintenance documents (for example IEC 61203) and other IEC publications on insulating liquids form the broader series of documents for fluid selection, testing and in‑service supervision.
Q: What are the key keywords?
A: Synthetic organic esters, insulating liquids, transformer fluids, switchgear fluids, test methods, specification, sampling, dielectric strength, viscosity, flash point.
