We offer a complete service of testing and certification to access the European market.

Sandwich panels are construction products made of steel sheets externally profiled that provide mechanical strength to an insulating core material such as polyurethane PUR, wools, PIR, or others. It is a common construction material for industrial plants, sports centres, or large facilities, and fulfils the functions of thermal and acoustic insulation.

International regulations (EU)

To access the European market, sandwich panels must meet the requirements of the quality and safety parameters defined in the Construction Products Regulation 305/2011 (CPR) scheme in regards to:

  • Mechanical resistance and stability
  • Fire safety
  • Health
  • Hygiene
  • Environment
  • Safety in use
  • Protection against noise
  • Energy saving
  • Thermal insulation


CE Marking

Standard EN 14509 (Self-supporting double skin metal faced insulating panels – Factory made products – Specification) regulates the CE marking of sandwich panels. A Notified Body must perform the required testing under this regulation in order for the product to acquire the certification. 
CE marking through ETAG (EOTA) 

Manufacturers of sandwich panels can also obtain their CE marking by way of the European Technical Approval Guideline (ETAG) 018. The European Technical Approval (ETA) is a document that comprises a technical assessment of the various characteristics of a product’s performance not covered, either partially or fully, by a harmonised technical specification. 

Our methodology

Our team of engineers studies each project to determine the optimal testing plan: 

  • Study of families of products to test according to their type and the desired market access conditions
  • Assessment of the number of test samples and design of the optimal testing plan.
  • Carrying out tests and issuing the corresponding reports. 
  • Issuance of an EXAP report where required for the extended application of fire resistance test results.


Applus+ is a Notified Body (NB 0370) for the CE marking of sandwich panels and we have a vast experience in providing this type of service in partnership with EOTA member organisations. We provide technological support to manufacturers of the construction industry in accordance with the Construction Products Regulation (CPR).

We carry out all relevant tests in our laboratories, according to the specifications of standard EN 14509:

  • Mechanical tests: grouped in families of flat panels and profiled panels. We test parameters of purity and type of core.
  • Durability tests: Applied to panels for external applications. This tests focus on the accelerated aging effect of temperature and humidity, which depends on each core material.
  • Thermal transmittance: These tests measure the thermal transmittance value of the panel (U), incorporating the declared thermal conductivity for the core material, the joints and any profiles facing.
  • Reaction to fire: Determined by the minimum and maximum thickness of each geometry and type of panel in order to cover the whole range. According to the appropriate Euroclass, we test under EN ISO 1182, EN ISO 1716, EN 13823 or EN ISO 11925.
  • Other related tests: external fire performance for roofs, fire resistance, water permeability, air permeability, airborne sound insulation, sound absorption, etc.
