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.

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.

Please first log in with a verified email before subscribing to ieo. A European Perspective Increasing population density and mobility, and mechanization of workplaces, households, and leisure activities, have resulted in increased general noise exposure for most people.

The excessive noise levels that can arise through unprotected or inadequately insulated installations are not just an annoyance for the employees; they are also a risk to their health.

Please first verify your email before subscribing to izo. In many cases, HVAC systems have served the dual purpose of temperature control and white noise.

He can be contacted at oilandgas armacell. Savings can be achieved, however, with efficient installation around more complex fittings.

The acoustic performance of these systems depends on the thickness and density of the materials. While installing foam insulation does require the knowledge of an experienced insulation contractor, it can be installed without special tools or equipment.


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

Among acoustic engineers, the general view is that noise from pipework can account for around half the total noise output sound power of a typical petrochemical or LNG liquefaction facility. In most cases, the new FEF systems greatly exceed the reductions required in the individual classes of the standard. Insulation contractors have all the materials on hand ios are necessary to control noise.

In most cases 115665 2 51665 are still handled separately by the respective design teams. Noise mitigation begins with the right choice of equipment, materials, and a well-planned layout to ensure minimal noise generation. You may delete a document from your Alert Profile at any time. In recent years, the demand for insulation with multifunctional capabilities has increased dramatically, and flexible foams have proven to be one of the suitable options for addressing numerous new challenges.

Standards Subsctiption may be the perfect solution. FEF insulation materials may be somewhat more expensive than traditional insulation materials.

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

Additionally, the material is flexible and can take a great deal of vibration and movement without degrading. If the document is revised or amended, you will be notified by email. When all appropriate measures to reduce noise at the source have been explored, insulating pipes is the most effective method of attenuating noise from process lines.

These composite multifunctional systems not only fulfill acoustic requirements, but they also provide stable thermal insulation performance, condensation control, and personal protection. Time is an extremely critical factor in any new-build construction 156665 the oil and gas industry.


The risk of accidents in the workplace also rises due to noise—such as when warning sirens or alarms are not heard.

Subscription pricing is determined by: FEF is flexible, which may reduce complexity during installation on pipework, bends, fittings, equipment, and vessels. 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.

Sound Control Insulation contractors have all the materials on hand that are necessary to control noise. Compressors, pumps, control, and relief valves generate significant noise levels, which are transmitted into the connecting pipework. Sound waves generated in industrial environments add up to noise that can be reduced with insulation.

Installation Specifics FEF is flexible, which may reduce complexity during installation on pipework, bends, fittings, equipment, and vessels. It is important to note, however, that when FEF is converted from closed to cell to open cell, the water transmission properties, both liquid and water vapor—as well as the thermal conductivity—are negatively impacted.

Given their ability to meet thermal, acoustic, and combined thermal-acoustic insulation needs, they offer a good option for many industrial applications.
