ISO 15665 PDF

Kaipro acoustic systems reduce noise transmission from industrial pipework, this online calculation tool shows the impact on overall noise levels when different. What is ISO ? ISO defines the acoustic performance of three classes (A, B and C) of pipe insulation. It is applicable to the acoustic insulation. ISO is the standard that is widely accepted in the industry for designing the acoustic insulation of pipes valves and flanges. Noise can be generated by.

ISO – Acoustics — Acoustic insulation for pipes, valves and flanges

The risk of accidents in the workplace also rises due to noise—such as when warning sirens or alarms are not heard. The failure of a selected system to satisfy the criteria set for all octave bands results in that system either being classified to a lower grade or alternatively remaining unclassified. Copyright Statement This article was published in the June issue of Insulation Outlook magazine.

FEF insulation materials may be somewhat more expensive than traditional insulation materials. Traditional soundproofing or acoustic insulation for industrial applications has often consisted of mineral wool, plastic foam, polyester, or fibrous material with a cladding outer shell or jacket made of aluminium, stainless, or galvanized steel sheets; loaded vinyl barriers; or metal jackets.

Increasing population density and mobility, and mechanization of workplaces, households, and leisure activities, have resulted in increased general noise exposure for most people. If these 2 teams operate without any coordination, it can lead to significant inefficiencies in design and result in insulation systems that are thicker or do not fulfill all system requirements. Noise-induced hearing loss is one of the most common occupational injuries. Space and weight are also crucial factors in the design, construction, and maintenance of oil and gas facilities.


While installing foam insulation does require the knowledge of an experienced insulation contractor, it can be installed without special tools or equipment.

BS ISO 15665:2003

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Specializing in environmental acoustics, he went on to receive a Ph.

Extensive studies have demonstrated that FEF layers can be combined isoo achieve excellent vibro-acoustic insulation performance suitable for noise control on industrial process pipelines.

In most cases, the new FEF systems greatly exceed the reductions required in the individual classes of the standard.

The construction of the system is sio according to the individual requirements of the plant to be insulated. Reduce Noise With Sound-Proofing Insulation Sound waves generated in industrial environments add up to noise that can be reduced with insulation. As the voice of the U. As in all industrial facilities, when planning the construction of a new oil or gas complex, the requirements for both thermal insulation and noise control must be fulfilled.

Is Your Application Acoustically Acceptable?

Excessive industrial noise also causes disturbance to neighboring residential communities, as well as adversely affecting the behavior of local fauna e. Multifunctional Thermal and Acoustical Solutions.

In cold or cryogenic processes, rigid, closed-cell insulation—such as polyisocyanurate or cellular glass—is often used to provide thermal protection and mineral wool insulation is layered on top for acoustical purposes. Already Subscribed to this document.

Development ios Elastomeric Noise Control Systems FEFs have been used for many years in industrial noise control, especially in applications where fibrous materials are not suitable. Noise is often increased when gases and fluids flow under high pressure or velocity, and turbulence is generated in the vicinity of obstacles such as valves or orifice plates, or as a result of changes in flow direction. Figure 51665 shows the test set up, including the sound 15665.


Compressors, pumps, control, and relief valves generate significant noise levels, which are transmitted into the connecting pipework. FEF is flexible, which may reduce complexity during installation on pipework, bends, fittings, equipment, and vessels.

These composite multifunctional systems not only fulfill acoustic requirements, but they also provide stable thermal insulation performance, condensation control, and personal protection.

Multifunctional Thermal and Acoustical Solutions

Sound Control Insulation contractors have all the materials on hand that are necessary to control noise. However, a short explanation of the test follows to aid understanding. The mean sound pressure level is measured using a microphone attached to a rotating boom in accordance with ISO in the frequency range of Hz to 10 kHz.

Given their ability to meet thermal, acoustic, and combined thermal-acoustic insulation needs, they offer a good option for many industrial applications. Acoustical insulation is of paramount importance in regard to personnel.

In order to account for changes in acoustic radiation efficiencies, the classification also makes a distinction depending on the pipe diameter. History Flexible foam insulation typically refers to elastomer-based materials consisting predominantly of synthetic rubber.

These new multi-layer constructions conform to the relevant classification criteria of ISO for the acoustic insulation of pipes, valves, and flanges. International Organisation for Standardisation.
