3-A Sanitary Standards, Inc (3-A SSI) is an American organisation that defines sanitary standards and rules for the design, manufacture, installation and cleanability of food equipment.

Accréditation de Conformité Sanitaire (ACS) is a French health standard for drinking water systems.

ASTM F838-05 is a standard test method for determining the bacterial retention of membrane filters used for liquid filtration. This test method determines the bacterial retention characteristics of membrane filters for liquid filtration using Brevundimonas diminuta as the test organism. This test method can be used to evaluate any membrane filter system used for liquid sterilization.

Name commonly given to the framework or legislation and directives for the control of explosive atmospheres and the standards for equipment and protective systems used in them.

German body BundesamtfürRisikobewertung (BfR) assesses and defines plastics used in the food industry.

European regulations concerning materials and equipment suitable for food contact

All pressure equipment put into service in Europe must comply with the Pressure Equipment Directive 2014/68/EU. This directive requires that all pressure equipment and assemblies above specified pressure and/or volume thresholds must comply with essential safety requirements covering design, manufacture and testing, satisfy appropriate conformity assessment procedures, bear the CE marking and/or other information.

The European standard specifies the filtering performance required by the system to provide good indoor air quality (IAQ) in relation to outdoor air.

This European standard specifies the requirements to be met before a medical device, which has undergone terminal sterilisation, can be labelled ‘STERILE’.

Part 2 of this European standard specifies the requirements for aseptic medical devices to be labelled ‘STERILE’.

This standard describes the test method for ‘Ultra High Efficiency Air Filters and Ultra Low Penetration Air Filters (HEPA and ULPA)’. It describes the test procedure and classifies the filters according to the results obtained.

This standard describes the test method for ‘general ventilation air filters for particle removal’, the test procedure and the classification of filters according to the results obtained.

Organisation that certifies the performance of air conditioning and refrigeration products, in accordance with European and international standards, to enable users to compare all equipment objectively. Gives rise to Eurovent certification.

European Ventilation Hygiene Association (Europe)

ISO 13485 specifies the quality management system requirements for the medical device industry. It is based on the requirements of the more general ISO 9001:2000 standard, in the context of this industry.

This international standard specifies the classification of air cleanliness in cleanrooms and other controlled environments. It is based exclusively on the concentration of suspended particles per unit volume.

This standard is the new global standard for the testing and classification of air filters and replaces the existing EN 779:2012 standard. The classification system is linked to the filter's performance according to three particle sizes: PM10, PM2.5 and PM1.

The Deutsche Vereinigung des GasundWasserfaches (DVGW) is an independent competence-sharing body for self-regulation in the gas and water industry in Germany and Europe.

This standard defines the minimum hygiene and protection requirements for materials used in the manufacture of food processing equipment.

Indoor air quality or IAQ refers to the gas and aerosol content, temperature and humidity of the air inside a structure. It is defined, among other things, by its capacity to preserve the health and well-being of the structure's inhabitants.

European Chemicals Regulation for the Registration, Evaluation, Authorisation and Restriction of Chemicals

The Class VI tests defined by the USP (United States Pharmacopoeia) are designed to assess plastics and elastomers intended for use in drug production equipment. This is a 4-part assessment involving in vivo biological reactivity tests in animals.

The Water RegulationsAdvisoryScheme (WRAS) is the UK water industry's accreditation system.
