Overview

FprEN 15501 (CEN) specifies requirements for factory-made expanded perlite (EP) and exfoliated vermiculite (EV) thermal insulation products used on building equipment and industrial installations. The standard covers products manufactured as boards, pipe sections, segments, prefabricated ware and special ware and is intended for service temperatures approximately 0 °C to +1 300 °C. It defines product characteristics and procedures for testing, evaluation of conformity, marking and labelling. Products may be used below 0 °C but require special suitability testing and manufacturer guidance.

Key Topics

  • Material scope: Expanded perlite (EP) and exfoliated vermiculite (EV) factory-made products.
  • Temperature range: Designed for applications roughly 0 °C to +1 300 °C (special testing advised for sub‑0 °C use).
  • Product forms: Boards, slabs, pipe sections (including split pipe), segments, blocks and prefabricated items.
  • Product characteristics and tests: Dimensional tolerances, thermal conductivity, apparent density, compressive and bending strength, dimensional stability, water vapour transmission, reaction to fire (see Annex B) and trace ion content. Test standards referenced include EN series and ISO methods (for example EN 1604, EN 13467, EN 13823, EN ISO 1716).
  • Conformity and factory control: Requirements for Initial Type Testing (ITT), Factory Production Control (FPC) and designation coding are included; Annex A addresses FPC procedures.
  • Marking and labelling: Rules for labelling products and CE marking information (Annex ZA) in relation to the EU Construction Products Directive.
  • Limitations: Does not set performance levels for specific applications (those are determined by regulations or tender documents). It does not cover in-situ (blown or poured) insulation, insulation of building structural elements or acoustical performance (airborne sound, impact noise index).

Applications

  • Insulation of mechanical building services (HVAC ducts, boilers, vessels) and industrial installations operating at low to very high temperatures.
  • Use by manufacturers to develop and declare product performance and by testing laboratories to perform standardized assessments.
  • Reference for specifiers, M&E engineers, architects and procurement teams when selecting EP/EV insulation for high‑temperature or corrosive environments where lightweight, refractory insulating materials are required.
  • Useful for conformity bodies and contract authorities during tendering and CE-marking assessments.

5.3.2 Thermal conductivity
For flat test specimens thermal conductivity shall be determined in accordance with EN 12667 or EN 12939 or EN
993-14 (when EN 993-14 is calibrated against EN 12667 or EN 12939). For cylindrical test specimens thermal
conductivity shall be determined in accordance with EN ISO 8497.
prEN 15501:2006 (E)
The tests in accordance with EN ISO 8497 may be replaced by tests in accordance with EN 12667, EN 12939 for
thick products or EN 993-14, provided it has been demonstrated that the results are safe (higher) values.
The thermal conductivity shall be determined for the full temperature range of the product. For FPC see annex A.
The thermal conductivity shall be determined directly at the measured thickness. If this is not possible it shall be
determined by measurements on other thicknesses of the product providing that:
 the product is of similar chemical and physical characteristics and is produced on the same production
unit/line;
 and it can be demonstrated that the thermal conductivity does not vary more than 10 % over the range of
thicknesses where the calculation is applied.
Where a product is manufactured in a range of thicknesses, and the manufacturer chooses to characterize the
entire range by declaring only one thermal conductivity, the highest thermal conductivity of the range shall be
declared.
In the case of pipe sections, measurements made on two internal diameters of pipe sections at the greatest and
smallest insulation thickness for each of the diameters are deemed to be representative of the total product range.
NOTE Suitable sizes are 48 mm and 194 mm internal diameter.
The guarded hot plate method, EN 12667 or EN 12939 for thick products or EN 993-14, shall be deemed to be a
suitable method for measurements of pipe sections having an internal diameter exceeding 500 mm. Flat slabs shall
be prepared having the same thickness and density as the sections.
In the case of special shapes, flat slabs of suitable thickness size compaction and density shall be prepared.
5.3.3 Maximum service temperature
Maximum service temperature shall be determined in accordance with EN 1094-6 at the declared maximum service
temperature. Specimens for testing the maximum service temperature of pipe sections, segments and special
shapes may be cut from flat boards with the same composition and density as the pipe section or segment product.
5.3.4 Reaction to fire
Tests shall be carried out in accordance with EN 13501-1.
Rules for mounting and fixing are given in annex B.
6 Designation code
A designation code for the product shall be given by the manufacturer. The following shall be included except when
there is no requirement for a property described in 4.3:
