Overview
The EN ISO 11111-4:2005/A2:2016 standard specifies safety requirements for textile machinery focused on yarn processing, cordage, and rope manufacturing machinery. Prepared jointly by ISO and CEN under the Vienna Agreement, this amendment enhances existing provisions with updated safety protocols and references, ensuring alignment with international safety principles for textile equipment.
This standard is particularly relevant to manufacturers, designers, and users of textile machinery operating within Europe and globally. It complements other standards that address noise emission and risk assessment, consolidating a comprehensive safety framework.
Key Topics
-
Safety Requirements for Yarn and Rope Machinery
The standard defines detailed safety measures tailored specifically to machines involved in yarn processing and cordage/rope production. These focus on hazard identification, risk reduction, and emergency controls.
-
Updated Technical References
Amendment 2 revises references to the foundational ISO 12100 on risk assessment and design principles, ensuring harmonization with the most current guidelines. It replaces earlier dated standards for better clarity and applicability.
-
Emergency Stop Devices
Requirements include the positioning of emergency stop pushbuttons, specifying that at least one such device must be located on each end of the machinery for rapid access in emergencies.
-
Machine Types Covered
The scope incorporates a variety of equipment such as tracked or horn gear machines and rotary-type braiding machines, including both solid and spiral braid configurations, reflecting industry diversity.
-
Noise Emission Measures
This standard is complemented by related type C standards such as ISO 9902 (parts 1 and 4) and ISO/DIS 23771, which cover noise measurement and reduction strategies important for protecting workers’ hearing and complying with environmental regulations.
Applications
-
Textile Manufacturing Facilities
Organizations producing yarns, cords, and ropes can implement this standard to ensure their machinery meets rigorous safety norms, reducing downtime due to accidents and boosting worker confidence.
-
Machinery Design and Engineering
Designers can use the guidance to develop safer equipment incorporating necessary safeguards, emergency controls, and ergonomic considerations that comply with international and European safety directives.
-
Compliance and Regulatory Adherence
The standard aligns with the EU Directive 2006/42/EC (Machinery Directive), granting a presumption of conformity for textile machinery that meet its requirements, facilitating market access within the European Economic Area.
-
Noise Control in Textile Machinery
Manufacturers looking to minimize the noise footprint of yarn and rope processing equipment benefit from the connection to complementary noise reduction standards, ensuring comprehensive health and safety management.
