General Information
- Abstract
This European Standard specifies the requirements for expanded perlite products which are used for the thermal insulation of building equipment and industrial installations with an operating temperature in the range of approximately –270 ºC to +650 ºC.
This European Standard specifies the requirements for the four types of expanded perlite products Perlite Aggregate (EPA), Coated Perlite (EPC), Hydrophobic Perlite (EPH) and Premixed Perlite (EPM), containing less than 1 % by mass organic material as determined by Annex C.
This European Standard is a specification for the insulation products before installation.
This European Standard describes the product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling.
This European Standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.
This European Standard does not cover factory made insulation products of formed shapes and boards made with expanded perlite, and does not cover products intended to be used for the insulation of buildings.
The products covered by this standard are not intended to be used primarily for airborne sound insulation or sound absorption applications although they may improve the performance of the installation in these respects when installed for their primary insulation intended use.

Overview
EN 15599-1:2010 - published by CEN - is the European specification for in‑situ thermal insulation formed from expanded perlite (EP) products. It applies to expanded perlite materials used to insulate building equipment and industrial installations with an approximate operating temperature range of –270 °C to +650 °C. The standard covers product characteristics, test procedures, evaluation of conformity, marking and labelling for products before installation and defines four product types: Perlite Aggregate (EPA), Coated Perlite (EPC), Hydrophobic Perlite (EPH) and Premixed Perlite (EPM). Products addressed contain less than 1% by mass organic material (Annex C).
Key topics and requirements
EN 15599-1:2010 specifies the required methods and declared characteristics rather than application‑specific performance limits. Key technical topics include:
- Thermal resistance and declared thermal conductivity (λD) - procedures for measuring and declaring thermal performance (see referenced test methods).
- Loose bulk density and particle size - requirements for loose‑fill handling and packing.
- Reaction to fire and continuous glowing combustion - safety and fire behaviour considerations.
- Durability characteristics - long‑term performance under service conditions.
- Maximum and minimum service temperatures (ST(+), ST(–)) - determination procedures (Annex D).
- Crushing resistance and mechanical stability for bonded and premixed products.
- Water vapour permeability (µ) - moisture transport attributes.
- Release of dangerous substances - compliance with chemical safety requirements.
- Sampling, conditioning and testing methods - including thermal conductivity test specimen preparation (Annex B) and factory production control (Annex A).
The standard includes procedures for initial type testing (ITT), evaluation of conformity and marking/CE labelling where applicable (Annex ZA addresses Construction Products Directive relations).
Applications and users
EN 15599-1 is intended for manufacturers, product designers, testing laboratories, specifiers and compliance engineers involved with:
- In‑situ insulation of plant equipment, pipelines, tanks and industrial installations
- HVAC, petrochemical, cryogenic and high‑temperature process systems
- Product certification, conformity assessment and CE marking for perlite insulation prior to installation
- Procurement and specification documents for contractors and asset owners
Note: this part is a pre‑installation product specification - it does not set fitness‑for‑purpose limits for specific installations. Those levels are defined by application regulations or complementary standards.

Annex C (normative) - Special conditions to be used for the determination of organic content Annex D (normative) - Determination of maximum service temperature Annex ZA (informative) - Clauses of this European Standard addressing the provisions of the EU Construction Products Directive This European Standard is one of a series for polyurethane/polyisocyanurate, expanded perlite and exfoliated vermiculite in-situ formed insulation products used in building equipment and industrial installations, but this standard may be used in other areas where appropriate. EN 14316-1 covers the use of expanded perlite in buildings. The reduction in energy used and emissions produced during the installed life of insulation products exceeds by far the energy used and emissions made during the production and disposal processes.

To comply with this standard, products shall meet the requirements of 4.2, and the requirements of 4.3 as appropriate. One test result for a product property is the average of the measured values on the number of test specimens given in Table 1. 4.2 For all applications 4.2.1 Thermal resistance and thermal conductivity Thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 (limited to 110 °C) or EN 993-14 (this test is calibrated against EN 12667). In each case the thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787. They shall be declared by the manufacturer according to the above specified measurement standards covering the product service temperature range. The following conditions apply: measured values shall be expressed with three significant figures; declared thermal conductivity curve shall be given as a limit curve, defined in EN ISO 13787; SIST EN 15599-1:2011
values below 0,1 W/(m·K) and in 0,001 W/(m·K) for
values above 0,1 W/(m·K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the equation, rounding upwards to the next 0,001 W/(m·K) has to be done for the full range of the thermal conductivity. NOTE The declaration of the declared installed thermal resistance for an installed EP product is made in EN 15599-2) 4.2.2 Loose bulk density Loose bulk density shall be determined in accordance with EN 1097-3. However, the container should be filled using a flat bottomed scoop held centrally over the container without touching it, and be no more than 50 mm above the rim. The value shall be expressed as kg/m3 and declared by the manufacturer in steps of 1 kg/m3. The loose bulk density shall be in the range of ± 15 % of the manufacturer’s declared value. NOTE Most expanded perlite products are in the range 30 kg/m3 to 180 kg/m3. 4.2.3 Particle size 4.2.3.1 Particle size distribution Particle size distribution shall be determined in accordance with EN 933-1 without washing and expressed as a percentage by mass, and shall be in accordance with the manufacturer’s declared limits. 4.2.3.2 Size designation The particle size shall be designated by two sieve sizes between which the main proportion of the material lies and any undersize or oversize shall comply with 4.2.3.3 and 4.2.3.4. The size in mm shall be selected from those specified in EN 13055-2. NOTE The particle size will normally be in the range 0 mm to 16 mm. 4.2.3.3 Undersize
The content of the undersize shall not exceed 15 % by mass. 4.2.3.4 Oversize The content of oversize shall not exceed 10 % by mass. 4.2.4 Reaction to fire This property is not measured since expanded perlite products described by this standard are classified without testing as class A1 products. NOTE 1 The products are classified without testing as class A1 products in accordance with commission decision 96/603/EC as amended by decision 2000/605/EC. NOTE 2 Products with an organic content greater than 1 % are outside the scope of this standard. If required the organic content shall be determined according to the procedure given in Annex C.
