EHEDG History

Based on an evolving knowledge in hygienic design, EHEDG published additional guideline documents in recent years and identified new assessment criteria for testing and certification. For the sake of food safety, equipment fulfilling the most recent design criteria is considered as the only one suitable for installation into food processing plants. In 2014, EHEDG therefore decided to review the whole certification process and introduced a revised certification scheme as well as new certification requirements. A new certification class was introduced for equipment used in open processes in close proximity to the product contact area, or for equipment which could have a potential influence on the product contact area, and where it could become soiled and must be cleaned in place. These types of equipment (e.g. conveyor drives, vision sensors, etc.) were newly categorized as type EL Class I AUX for auxiliary equipment. The existing type ED was divided into two categories according to the EHEDG definitions, type ED Class I (dry cleaning without dismantling) and type ED Class II (dry cleaning with dismantling).

EHEDG History

Due to an increasing demand from the industry for certification of other component types, EHEDG revised the EL certification scheme in 2009 and introduced several new certificate types. Equipment was now categorized as Class I and Class II according to the equipment definitions, subject to be either cleaned in-place (Class I) or to be dismantled for cleaning (Class II). Equipment used in aseptic applications has been certified since that time according type EL Aseptic. Another special certificate type ED was created, being meant for equipment used for dry cleaning procedures.

EHEDG History

Starting in the year 2000, EHEDG established the EL certification scheme for liquid handling equipment. The EL certificate was mainly meant for equipment intended to be cleaned in-place (CIP) without dismantling. The equipment was certified (and a logo placed on the equipment) if it was in accordance to EHEDG Document No. 8 on Hygienic design criteria. The equipment was subjected to practical testing using Guideline Doc. 2 to demonstrate compensation for non-compliance for essential technical or functional reasons and suitability for cleaning in-place applications.
