Overview
EN ISO 9902-7:2001/A1:2009 is Amendment 1 to the noise test code for dyeing and finishing textile machinery. Prepared in collaboration between ISO/TC 72 (Subcommittee SC 8) and CEN/TC 214, this draft amendment updates normative references, clarifies scope, and includes CEN annexes relating to EU machinery directives. The amendment supports consistent measurement of noise emitted by dyeing and finishing equipment and helps manufacturers and test laboratories align with regulatory requirements.
Key Topics
-
Scope updates: The amendment explicitly applies to engineering (grade 2) and survey (grade 3) methods and covers machines as defined in ISO 1506 used for:
- preparation
- dyeing
- printing and coating
- fixing, wetting and drying
- finishing
- calendering
- making-up of presentation
-
Reference updates: A key change is the replacement of references to ISO 9902-1:2001 by ISO 9902-1:2009 across multiple clauses and tables. The amendment also removes specific publication years for several referenced standards and replaces ISO 11203:1995 with ISO 11203 (no year specified).
-
Regulatory alignment: The draft adds informative annexes (ZA, ZB, ZC) that describe the relationship between the standard and the Essential Requirements of EU Directives (notably 98/37/EC and 2006/42/EC). These annexes explain how compliance with the normative clauses supports a presumption of conformity to relevant Machinery Directive requirements.
Applications
This amendment is practical for:
- Manufacturers of dyeing and finishing machinery who need consistent noise test procedures for product documentation and CE marking.
- Test laboratories conducting engineering-grade and survey-grade noise measurements on textile machinery.
- Regulatory and compliance teams seeking to reference harmonized standards that relate to the Machinery Directive and national implementation.
Benefits include improved consistency of noise measurement reporting, up-to-date normative references, and clearer linkage to EU essential requirements for market access.
Related Standards

- ISO 1506 - Definition and classification of textile machinery types (as used in scope)
- ISO 11203, ISO 11201, ISO 11202, ISO 11204 - referenced acoustic measurement standards
Note: This document is a draft amendment circulated for enquiry (2008) and, if approved, modifies EN ISO 9902-7:2001. It should be used in conjunction with the full standard texts and national implementations when applied for regulatory compliance.
