This document provides the product category rules (PCR) for Type III environmental declarations (as in EN 15804:2012+A2:2019 1) for factory made and in situ thermal insulation products.
Complementary to EN 15804:2012+A2:2019 1, the PCR described in this document:
— specify the declared unit to be used;
— define the system boundaries for thermal insulation products;
— specify/describe the default scenarios and rules for defining scenarios for certain life cycle information modules.
These PCR are intended to be used for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intention is properly stated in the system boundary description.

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.
