Overview
ISO 10821:2005/Amd 1:2009 is an important amendment to the internationally recognized standard on industrial sewing machines focusing specifically on safety requirements for sewing machines, units, and systems. Published by the International Organization for Standardization (ISO), this amendment updates and refines safety protocols originally established in ISO 10821:2005 to address evolving technological and operational needs within the sewing machinery industry. This document serves as a critical reference for manufacturers, safety engineers, and compliance officers to ensure machinery meets robust safety benchmarks.
Key Topics
This amendment provides detailed updates impacting several critical areas of industrial sewing machine safety, including:
-
Safety-Related Control Systems
Clarifies performance levels for safety-related parts of control systems:
- Stitch form element hazards require compliance with performance level b of ISO 13849-1:2006.
- Other industrial sewing machines are required to meet performance level c of the same standard.
-
Acoustic Noise Measurement
Updates normative references to ISO 3747:2000 for sound power level determination, with adjustments to noise level thresholds and correction methodologies:
- Reduces the maximum permissible sound pressure level from 85 dB to 80 dB to enhance operator safety.
- Clarifies measurement surface dimensions and background noise correction for precise acoustic assessments.
-
Machine Marking and Identification
Outlines mandatory legible and indelible markings for sewing units and systems, including:
- Manufacturer's business name and address.
- Machine designation, series or type, and serial number.
- Year of construction.
- Mandatory safety markings.
-
Safety Device Requirements for Embroidery Machines
Specifies that certain protective shields (e.g., for needle breaks or finger deflectors) may be omitted where the machine's design inherently mitigates these hazards.
-
Spare Parts Specifications
Introduces requirements for including specifications of spare parts that affect operator health and safety in machine documentation.
-
Normative References Updates
Incorporates the latest editions of related standards:
- ISO 13849-1:2006 (Safety-related parts of control systems).
- IEC 60204-1:2005 (Electrical equipment of machines).
- IEC 60825-1:2007 (Safety of laser products).
Applications
ISO 10821:2005/Amd 1:2009 is essential for:
-
Manufacturers of Industrial Sewing Machines
Ensures that new and existing machines comply with updated safety and noise emission standards, reducing workplace hazards and improving product reliability.
-
Safety and Compliance Professionals
Provides a clear regulatory framework to audit, certify, and improve safety controls on industrial sewing equipment and related systems.
