Overview

EN ISO 20361:2019/A11:2020 is the CEN amendment to the international standard ISO 20361:2019, titled Liquid pumps and pumps units - Noise test code - Grades 2 and 3 of accuracy. Published as an amendment (A11) in March 2020 and adopted into European standards, it updates the noise test code applicable to liquid pumps and pump units. The standard is aimed at consistent measurement and reporting of noise emissions from pumps and supports conformity assessment under EU machinery rules (Directive 2006/42/EC).

Key topics

• Scope and status: Amendment A11 modifies EN ISO 20361:2019 and must be implemented by CEN national bodies; the document exists in English, French and German.
• Noise test code: Specifies the framework for acoustic testing of liquid pumps and pump units at accuracy Grades 2 and 3 (measurement precision levels used in pump noise testing).
• Conformity linkage: Includes Annex ZA explaining how compliance with the standard provides a presumption of conformity with essential noise-related requirements of Directive 2006/42/EC.
• Standardization context: Prepared by CEN/TC 197 (secretariat AFNOR) and referenced under ICS codes 17.140.20 (noise emission) and 23.080 (pumps).
• Implementation timeline: Approved 11 March 2020; national adoption required by September 2020 (per CEN procedures).

Note: This summary focuses on the standard’s content and status. The standard itself contains the specific test protocols, measurement conditions and reporting formats - consult the full text for procedural details.

Applications

• Manufacturers of liquid pumps and pump units: to design, test and declare acoustic performance consistently.
• Acoustic test laboratories: to perform reproducible noise measurements at the defined accuracy Grades 2 and 3.
• Regulatory and conformity assessment bodies: to assess compliance with EU machinery noise requirements and support CE marking.
• Procurement and specification teams: to set objective noise-performance requirements in tenders and contracts.
• Consultants and health & safety professionals: for noise impact assessment and selection of low-noise pump solutions.

Practical benefits include consistent test results, clearer supplier declarations, improved comparability between products, and a recognized route to demonstrate conformity with EU machinery noise regulations.

Related standards

• ISO 20361:2019 (base international standard)
• Relevant EU Directive: Directive 2006/42/EC (Machinery Directive) - Annex ZA of the amendment maps clauses to essential requirements for noise emissions.
