These terms are interchangeable and refer to "a method of assessing the in-place cleanability of food processing equipment" described in EHEDG Guideline 2. The test method is used as a basic screening test for hygienic design. It is used to determine if areas (or features) within a piece of equipment are “easily cleanable” by comparing the test results to that of a standard reference pipe soiled and cleaned during the same test. Due to inherent variability in the cleaning of equipment, the test must be repeated successfully at least 3 times for equipment to be eligible for certification. This test is required for equipment to be certified as Type EL Class I and EL Aseptic Class I.
All closed pieces of equipment which are installed in a pipeline, e.g. pumps, valves, and inline sensors, must be tested according to the method of EHEDG Guideline 2. This test is a screening test for hygienic design and identifies areas that may contain a crevice which can trap soil and microorganisms or are not easily cleaned due to the flow dynamics.
Closed equipment which fully comply with the hygienic design requirements can be certified without testing. Examples are pipe lines or pressure sensors without elastomeric seals.
- Both open and closed equipment used in food processing environments can be certified. A list of all EHEDG certified components is published on Certified Equipment
- Although there are no limitations on the complexity of the piece of equipment, typically only small, individual components are certified rather than large, complex machines or processing systems.
- For certification of open equipment, ALL equipment surfaces are evaluated as product contact surfaces and must meet all hygienic design criteria in relevant EHEDG guidelines.
- Currently, only closed equipment with pipe connections between 25 mm (1 in) O.D. and 75 mm (3 in) O.D. can be tested due to limitations of CIP testing.
For closed equipment components intended to be cleaned in-place (CIP) with liquids (EL CLASS I certified), only the internal, wetted surfaces/parts are evaluated and certified to meet the hygienic design criteria according to EHEDG guidelines. This means that for pumps, valves and in-line sensors; the motor, drive, actuator or frame (if present) are NOT evaluated and certified for cleanability according to EHEDG guidelines. Only the internal, product contact surfaces are evaluated and certified according to EHEDG guidelines and, if necessary, tested for easy cleanability according to EHEDG Guideline 2.
In general, all sizes of the same piece of equipment must be evaluated with a design review and CIP tested prior to certification. However, in a few instances where equipment designs are considered completely scaleable by an EHEDG AEO, testing of only one size can be used for certification of the entire range. In most instances, equipment is NOT completely scaleable. Currently, the only alternative to testing each size is to perform computational fluid dynamics modelling (CFD) of the different designs to select the size for testing that may be the most difficult to clean based on wall shear stresses and fluid exchange in critical areas. If the selected size passes CIP testing, the sizes with higher wall shear stresses and fluid exchange in critical areas may also be considered for certification and listed on the same certificate.
No. Since open equipment cannot currently be tested to ensure cleanability, open equipment intended to be cleaned with liquids can only be certified as EL Class I AUX or EL Class II. Open equipment intended to be dry cleaned only can be certified as ED Class I or Class II.
EL Class I is only for closed equipment, intended to be cleaned-in-place (CIP) with liquids, and can be CIP tested using the method of Doc. 2. EL Class I AUX is for certification of auxiliary open equipment which is intended to be cleaned-in-place with liquids but not tested. EL Class II is for equipment which is intended to be cleaned with liquids but must be disassembled or dismantled prior to cleaning.
Different elastomers may have different material properties. Experience has shown that different materials in the same mechanical design may affect the equipment cleanability. Since 2009 the certificate lists the elastomers that were CIP tested. The equipment is only certified when used with the elastomers listed on the certificate. Each elastomer listed on the certificate must be CIP tested using the method of EHEDG Guideline 2.
If the test programme was conducted after 1st January 2008 the report may still be valid for re-certification purposes if the design and materials have not been changed. Consult an AEO for review.
Valid certificates in the EHEDG database might be highlighted with a "Renewal Pending" flag if subject to renewal, but the renewal process hasn't been completed yet. To be subject to renewal,
- The certificate must have already been expired
- An application for renewal must have been handed in on time
- The component must have successfully passed the hygienic design evaluation phase
- The component must be tested
The component might still fail the test. In this case the "Renewal Pending" flag will be withdrawn and the certificate will be removed from the database.
The use of the ‘EHEDG certified’ logo on marketing material is allowed, per the EHEDG certification contract.
EHEDG, in conjunction with the nominated AEO, will issue a revised certificate with the new name on it as a revision. The 5-year renewal date will not be reset. However, if there have been any changes to the EHEDG Hygienic Design Criteria or Test Methods a new certification procedure is required.

If an organisation is in need of several copies of the same EHEDG guideline for several employees, multiple orders need to be placed. Alternatively, the organisation may consider to register as an EHEDG company or institute member, allowing up to 100 staff members to have an EHEDG account, and the right to download a personal copy of each guideline free of charge. Please check our membership conditions.
A proposal to draft a new guideline, or to revise an existing document, should first be approved by the Sub-Committee Product Portfolio and the EHEDG Executive Committee (ExCo). If approved, the project is assigned to a dedicated Working Group. Upon formation (or re-activation) of a dedicated Working Group, guidelines are developed with a consensus-based approach. All documents are subject to a 5-year review policy. In the end of the 5-year cycle, the Working Group determines whether the guideline should be modified to meet the current industry needs, and then re-issued, or be discontinued.
Please see the overview of our Working Groups on our website.
When having identified a topic of interest to the relevant industries, all EHEDG members are welcome to send in to the Office a new guideline or revision proposal (PDF). The topic will be subject to approval by the Product Portfolio Sub-Committee and the EHEDG ExCo.
