Full title and description

STB DIN EN ISO 23771 E 2013-06 — Design measures for reduction of the noise emissions from textile machinery (prEN ISO 23771:2013). This entry refers to the June 2013 prEN/pr draft English-language release of the DIN adoption of the ISO draft providing guidance on design measures to reduce noise from textile machines.

Abstract

This document (prEN ISO 23771:2013) presents guidance for designers and manufacturers of textile machinery on identifying significant noise sources and implementing design measures to reduce noise emissions. It addresses typical noise-generating elements of textile machines and suggests engineering controls and layout, enclosure and component choices intended to lower machine sound levels and occupational noise exposure. The draft was subsequently developed into the published ISO 23771:2015 guidance.

General information

• Status: Draft/prEN (June 2013) — withdrawn/superseded by the published ISO/DIN adoption in 2015.
• Publication date: prEN / draft date: 24 June 2013 (denoted 2013-06); final international standard published as ISO 23771 in 2015 (see Notes).
• Publisher: DIN (adoption of the EN/ISO draft); original work as ISO draft leading to ISO 23771 (ISO).
• ICS / categories: 17.140.20 (Noise emitted by machines and equipment); 59.120.01 (Textile machinery in general).
• Edition / version: prEN ISO 23771:2013 (draft English version, indicated by the E suffix in the designation).
• Number of pages: Approximately 35 pages for the 2013 draft; the later ISO 23771:2015 edition is 28–39 pages depending on the adopted national version.

Scope

The draft standard gives guidance for the technical design of textile machinery so as to reduce noise emissions where machines present a significant noise hazard (as defined by the ISO 11111 series of textile‑machine safety standards). It focuses on in‑machine sources and design measures (component selection, layout, enclosures, isolation, damping, and maintenance considerations) rather than external, non‑machine elements such as factory conveyors or building services. The 2013 draft was intended to be adopted as an EN/DIN version and subsequently developed into the 2015 ISO publication.

Key topics and requirements

• Identification of significant noise sources typical for classes of textile machines (rollers, spindles, gearboxes, drives, material handling points).
• Design principles for noise reduction: elimination at the source, substitution, engineering controls (enclosures, barriers, damping), component selection and isolation.
• Guidance on acoustic treatment of machine housings, openings and operator interfaces to balance access and noise control.
• Recommendations on bearings, gear design, drive systems and maintenance practices that affect noise emission.
• Reference to related safety and measurement standards (notably the ISO 11111 series) for assessing noise hazards and conformity.

Typical use and users

Used by textile‑machine designers and manufacturers during concept and detailed design to reduce machine sound emissions; by acoustical and mechanical engineers performing noise‑control design; by safety and occupational‑health professionals assessing workplace noise risk; and by standards committees and conformity bodies as the draft basis for national adoption. The draft also served as input to the final ISO 23771:2015 international standard.

Related standards

Directly related to and developed alongside the ISO 11111 series of "Textile machinery — Safety requirements" (which define machines with significant noise hazards). The 2013 draft was superseded by ISO 23771:2015 (Textile machinery — Guide to the design of textile machinery for reduction of the noise emissions), and national adoptions such as DIN EN ISO 23771:2015 were published.

FAQ

Q: What is this standard?

A: It is the prEN / draft version of DIN EN ISO 23771 released in June 2013 (designation shown as STB DIN EN ISO 23771 E 2013-06), providing guidance on design measures to reduce noise emissions from textile machinery. The draft was later developed into the published ISO 23771:2015.

Q: What does it cover?

A: It covers identification of typical noise sources in textile machines and recommended engineering design measures — such as selecting lower‑noise components, enclosures, isolation, damping, and layout choices — to reduce emitted sound levels and occupational exposure.

Q: Who typically uses it?

A: Machine designers and manufacturers, acoustical/mechanical engineers, occupational safety professionals, and standards bodies use this guidance when designing or assessing textile machinery for lower noise emissions.

Q: Is it current or superseded?

A: The 2013 prEN draft is not the final international standard; it was superseded by the published ISO 23771:2015 and the corresponding national EN/DIN adoptions (DIN EN ISO 23771:2015). The 2013 draft entry is therefore considered withdrawn/superseded in favor of the 2015 publication.

Q: Is it part of a series?

A: Yes — it is linked to the ISO 11111 series (Textile machinery — Safety requirements) which identifies textile machines with significant noise hazards; ISO 23771 provides complementary guidance on design measures to reduce those noise emissions.

Q: What are the key keywords?

A: Noise reduction, textile machinery, acoustic design, noise emission, ISO 23771, ISO 11111, machine safety, design guidance.
