During the construction of industrial, warehouse, commercial and logistics facilities, the quality of sandwich panels directly affects the reliability of the building, its energy efficiency and service life. That is why, in the international market, special attention is paid not only to the characteristics of finished products, but also to the compliance of materials with current quality and safety standards.
International standards allow an objective assessment of the strength of panels, thermal insulation properties, fire safety and resistance to external influences. For customers, this serves as confirmation that the material is able to maintain the declared characteristics for many years of operation.
What international standards apply to sandwich panels?
Modern manufacturers are guided by several groups of standards that regulate both production processes and the parameters of finished products. The availability of appropriate certificates attests to the passage of tests and compliance with the established requirements. The most common standards are the following:
• ISO 9001, which defines the requirements for an enterprise’s quality management system.
• EN 14509, which establishes requirements for self-supporting sandwich panels with metal linings.
• EN 13501-1, used to classify building materials by reaction to fire.
• ISO 12944, which regulates the protection of metal surfaces from corrosion.
• EN ISO 6946, used to calculate the heat transfer resistance of building structures.
Compliance with these standards allows manufacturers to confirm the stability of product characteristics and ensure a high level of control at all stages of production.
What characteristics are checked during the tests
Obtaining certificates is impossible without conducting laboratory and operational tests. During the testing, the indicators that have a direct impact on the reliability of the future building are evaluated. When checking the quality of sandwich panels, the following parameters are analyzed:
• Bonding strength of metal linings with insulation.
• Load-bearing capacity of the structure under static loads.
• Coefficient of thermal conductivity of the thermal insulation layer.
• Water absorption and resistance to moisture.
• Tightness of lock connections.
• Resistance to wind loads and deformations.
The test results allow us to determine how well the material meets the stated characteristics and requirements of building regulations. For large facilities, such indicators are of particular importance, as they directly affect operational safety.
Fire safety and durability of materials
One of the key criteria for quality assessment is the ability of panels to maintain their properties when exposed to high temperatures. Depending on the type of insulation, products may have different indicators of fire resistance and fire safety. Special attention is paid to the following characteristics during certification:
• Reactions of the material to exposure to open fire.
• The speed of flame propagation over the surface of the structure.
• Intensity of smoke formation.
• Preservation of load-bearing capacity during heating.
• Resistance of protective coatings to external influences.
Durability is considered an equally important factor. To check the stability of metal linings, tests for corrosion resistance, UV exposure, temperature fluctuations and high humidity are used. Such tests make it possible to predict the service life of panels in various climatic conditions.
Why is compliance with standards important for the customer
International standards help to compare products from different manufacturers according to the same criteria. The customer gets the opportunity to evaluate not only the cost of the material, but also its actual operational characteristics, confirmed by tests and certification.
By choosing sandwich panels that meet international quality requirements, you can rely on reliable structures, effective thermal insulation and a long service life of the facility.
