Description (English):

La présente partie de l'ISO 9902, conjointement à l'ISO 9902-1, spécifie les conditions de montage, de fonctionnement et de mesurage nécessaires pour le mesurage, la déclaration et la vérification du bruit émis par différents types de machines de préparation de filature et machines de filature. Elle est applicable aux méthodes d'expertise (classe 2) et de contrôle (classe 3), conformément aux Normes internationales auxquelles il est fait référence, et à différents types de machines utilisées comme défini dans l'ISO 2187 pour: - ouvraison, nettoyage, mélange, - lavage de la laine, - mise en balles, - cardage, - coupe et craquage de câbles de filaments, - préparation à la filature après le cardage, et - filature.

Abstract

Overview

ISO 9902-2:2001 - "Textile machinery - Noise test code - Part 2: Spinning preparatory and spinning machinery" specifies the acoustic measurement, declaration and verification requirements for noise emitted by spinning preparatory and spinning machinery. It is intended to be used together with ISO 9902-1:2001 (Common requirements) and defines how to determine A‑weighted sound power (LWA) and emission sound pressure levels (LpA) for machine families used in spinning preparation, carding, scouring, baling and spinning operations.

Key keywords: ISO 9902-2:2001, textile machinery, noise test code, spinning machinery, sound power, emission sound pressure, acoustic measurement.

Key topics and requirements

Scope and applicability
- Applies to spinning preparatory and spinning machines (e.g., opening/cleaning/blending, carding, spinning).
- Covers engineering (grade 2) and survey (grade 3) measurement methods.
Measurement methods
- Sound power determination: use of sound intensity (ISO 9614‑1 / ISO 9614‑2) or sound pressure methods (ISO 3744, ISO 3747; ISO 3746 only if others not practicable).
- Emission sound pressure at workstations: use ISO 11201 or ISO 11204 (ISO 11202 only where 11201/11204 are impracticable).
- Results expressed as A-weighted levels (LWA, LpA).
Workstation definitions and measurement positions
- Defines three options (d, e, f) for selecting measurement positions - e.g., measurement line 1 m from machine surface at 1.6 m height, or three- or nine-point grids at 1.6 m.
- In restricted spaces measurement distance may be reduced to 0.5 m (must be reported).
Test conditions and reporting
- Installation, mounting and operating conditions are specified (see ISO 9902‑1 and Table 1 of Part 2).
- Table 1 prescribes machine-family specific equipment inclusion/exclusion, operating parameters to report, and when machines are classed as “very large.”
- Requirements for measurement uncertainty, information to record and report, and declaration/verification procedures.

Applications and users

Who uses it:
- Textile machinery manufacturers for design validation and noise declarations.
- Acoustic test laboratories performing product conformity tests.
- Occupational safety engineers assessing workplace noise exposure.
- Procurement and compliance teams requiring verified noise data.
Practical uses:
- Producing standardized noise declarations for product data sheets.
- Verifying supplier noise claims during acceptance testing.
- Informing noise control measures, machine layout and hearing protection strategies in textile plants.

ISO 3744 / ISO 3746 / ISO 3747 (sound power by sound pressure)
ISO 9614-1 / ISO 9614-2 (sound intensity)
ISO 11201 / ISO 11202 / ISO 11204 (emission sound pressure at workstations)
ISO 2187 (terminology for spinning machinery)
Other parts of ISO 9902 (Parts 3–7 cover nonwoven, yarn/fabric processing, weaving, dyeing/finishing)

This standard is essential when consistent, comparable acoustic data for spinning and preparatory textile machinery are required for compliance, design and occupational noise control.
