SIST EN ISO 8224-1:2004/A1:2013 PDF

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.
