Acoustics — Acoustic insulation for pipes, valves and flanges

Edition date: 2023-12-18
In Force
Available languages: French, English
Summary:

This document defines the acoustic performance of four classes (Classes A, B, C and D) of pipe insulation. It also defines a standardized test method for measuring the acoustic performance of any type of material system construction, thereby allowing existing and new insulation constructions to be rated against the four classes. Furthermore, this document presents some typical types of construction that would be expected to meet these acoustic performance classes.

This document is applicable to the acoustic insulation of cylindrical steel pipes and to their piping components. It is valid for pipes up to 1 m in diameter and a minimum wall thickness of 4,2 mm for diameters below 300 mm, and 6,3 mm for diameters from 300 mm and above. It is not applicable to the acoustic insulation of rectangular ducting and vessels or machinery.

This document covers both design and installation aspects of acoustic insulation and provides guidance to assist noise control engineers in determining the required class and extent of insulation needed for a particular application. It gives typical examples of construction methods, but the examples are for information only and not meant to be prescriptive.

This document emphasises the aspects of acoustic insulation that are different from those of thermal insulation, serving to guide both the installer and the noise control engineer. Details of thermal insulation are beyond the scope of this document.



Le présent document définit les performances acoustiques de quatre classes (classes A, B, C et D) d'isolation de tuyaux. Il définit également une méthode d'essai normalisée pour mesurer les performances acoustiques de tout type de construction de système de matériau, permettant ainsi d'évaluer de nouvelles isolations et les isolations existantes par rapport aux quatre classes. En outre, le présent document décrit certains modes de construction types susceptibles de satisfaire à ces classes de performances acoustiques.

Le présent document est applicable à l'isolation acoustique de tuyaux cylindriques en acier et de leurs composants de tuyauterie. Il est valable pour des tuyaux jusqu'à 1 m de diamètre et d'une épaisseur de paroi minimale de 4,2 mm, pour des diamètres inférieurs à 300 mm et de 6,3 mm, pour les diamètres supérieurs ou égaux à 300 mm. Il n'est pas applicable à l'isolation acoustique de conduits rectangulaires, ni à celle de réservoirs ou de machines.

Le présent document traite de l'évaluation des performances d'isolation acoustique des tuyaux à la fois en phase de conception et sur des installations en exploitation. Il fournit des lignes directrices aux ingénieurs acousticiens pour déterminer la classe requise et l'étendue d'isolation nécessaire pour une application donnée. Il fournit des exemples types de méthodes de construction, ces exemples étant toutefois fournis à titre informatif uniquement et n'ont pas pour objet d'être normatifs.

Le présent document précise les aspects de l'isolation acoustique qui diffèrent de ceux de l'isolation thermique, et sert de guide tant aux installateurs qu'aux ingénieurs acousticiens. Les détails afférents à l'isolation thermique sont exclus du domaine d'application du présent document.

  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.

Once the "Customer data" form has been completed, "Order in progress" will be displayed with all the items loaded in the shopping cart, their prices, taxes established in current legislation and shipping costs if applicable.

The prices of the standards and books that appear in the various sections do not include taxes or shipping costs.

AENOR promotional codes consist of alphanumeric characters and can only be applied to online purchases, received through a specific offer and for a limited time. To apply your promotional code, you just have to enter it in step 2 of 4 of the purchase process on the website and click on "apply", after you have identified yourself and chosen the payment methods. Promo codes are not cumulative.
