Overview
EN ISO 8224-1:2003/A1:2011 (Traveller irrigation machines - Part 1: Operational characteristics and laboratory and field test methods - Amendment 1) is a CEN-adopted amendment to the international standard that defines laboratory and field test methods and the assessment of operational characteristics for traveller (mobile) irrigation machines. Prepared by ISO/TC 23 and CEN/TC 334, this amendment updates normative references and refines laboratory uniformity and water-distribution test procedures.
Key topics and technical requirements
- Scope: Specifies test methods to evaluate operational behaviour and performance of traveller irrigation machines in both laboratory and field conditions.
- Normative references updated:
- Deleted: ISO 7749-2:1990
- Added: ISO 15886-3:2004 (Agricultural irrigation equipment - sprinklers - Part 3: Characterization of distribution and test methods)
- Laboratory uniformity tests (Clause 6):
- Preparation procedures revised to reference ISO 15886-3:2004 instead of the removed ISO 7749-2.
- Specific editorial changes were made to pre-test data and test setup instructions (for example, text relating to can spacing and certain prescriptive sentences were replaced or removed).
- Water distribution patterns: The amendment replaces earlier references and clarifies how to obtain and document stationary water distribution patterns for pre-test data using the requirements of ISO 15886-3:2004.
- Editorial and procedural clarifications: The amendment removes or alters specific prescriptive sentences (e.g., certain dimensional checks and catch-can grid instructions) to align test methods with the updated sprinkler-characterization standard.
Applications and users
This amendment and the parent standard are directly applicable to:
- Manufacturers of traveller (mobile) irrigation machines for product development and performance claims.
- Test laboratories conducting laboratory uniformity and field performance tests.
- Certification bodies and regulators that reference standard test methods for compliance and approvals.
- Agricultural engineers, irrigation designers and contractors who need reliable performance data for system selection and design.
- Research organizations and universities working on irrigation efficiency, water distribution and machine optimisation.
Related standards
- ISO 15886-3:2004 - now referenced for sprinkler characterization and test methods (key normative reference introduced by this amendment).
- The amendment modifies EN ISO 8224-1:2003; users should consult the base Part 1 text together with this A1 amendment for complete test procedures and requirements.
