IASH History

Nahum Por’s Vision becomes IASH and Establishes an International Community


The association was initiated by the vision of Nahum Por, a scientist at Oil Refineries Ltd. with the support of the Israel Institute of Petroleum & Research, when the Long Term Storage Stabilities of Liquid Fuels conference was held in July 1983 in Tel Aviv with 120 delegates in attendance from 11 countries.

His initiative and incentive were instrumental in the formation of the International Association for Stability and Handling of Liquid Fuels (IASH) three years later in 1986. The words “and use” were added to the name in 2005. In over three decades since that first auspicious meeting, IASH has become the world’s foremost international organization devoted to all aspects of the stability, handling and use of liquid fuels.

IASH is an international, non-political, non-commercial, not-for-profit association that relies on volunteers to maintain its autonomy from any single organization or company. Membership is open to all individuals and organizations subscribing to the goals and ideals of IASH. Currently, the association has over 200 members from 25 countries worldwide. They represent academe, government, industry and other sectors associated with the petroleum industry. Their interests span the time from when fuels are produced in a refinery until they are burned in a power plant, engine furnace, or turbine.
