Overview
SIST EN ISO 9902-1:2002/A1:2009 is an amendment to the international standard ISO 9902-1:2001 concerning noise testing procedures for textile machinery. Published by CEN (European Committee for Standardization), this amendment updates the common requirements for noise measurement in textile machinery to align with current technological and regulatory standards.
This standard forms a crucial part of the ISO 9902 series and supports compliance with essential safety and environmental requirements stipulated by European directives such as the Machinery Directive 2006/42/EC. It provides a harmonized noise test code ensuring consistent evaluation of airborne noise emissions from textile machinery and related equipment.
Key Topics
-
Noise Test Code for Textile Machinery
The standard specifies common requirements for measuring noise emissions, including methods and guidelines to produce reproducible and comparable noise test results.
-
Adaptation to Updated References
SIST EN ISO 9902-1:2002/A1:2009 revises and updates normative references by removing publication years and replacing outdated standards (e.g., EN 292-2 replaced by ISO 12100-2 on machinery safety principles).
-
Scope Extension
The amendment clarifies applicability to all textile machinery, plants, and equipment as defined in ISO 11111 parts 1 to 7, supporting a comprehensive coverage across the textile manufacturing sector.
-
Noise Measurement Parameters
Terms such as A-weighted sound power level and emission sound pressure level are defined and adapted referencing the latest ISO noise measurement standards (e.g., ISO 3740 series).
-
Declaration of Noise Emissions
Updated requirements emphasize that airborne noise emission information must accompany machinery documentation following ISO 12100-2, facilitating transparent communication for manufacturers and users.
-
Compliance with European Directives
The amendment includes informative annexes detailing the relationship between this standard and EU Directives (2006/42/EC and 98/37/EC), offering machinery manufacturers presumption of conformity when adhering to this standard.
