Testing and Certifications for Industrial Fasteners

Testing, inspections and certifications are essential elements in supplies of industrial fasteners and fastening systems intended for technical applications. In many sectors, it is not sufficient to supply a component that is dimensionally compliant. It is necessary to document materials, mechanical characteristics, test results, non-destructive inspections and dimensional checks. EFS relies on specialized laboratories to carry out quality inspections, mechanical testing, documentation checks and certifications required by the customer or by the technical specification.

Technical documentation makes it possible to ensure greater traceability and control over the supply. Depending on the sector and application, the customer may require material certificates, mechanical testing, non-destructive inspections, dimensional reports or documentation validated by third-party bodies. EFS supports the management of these requests by coordinating the process with qualified laboratories and manufacturers.

3.1 certification is an inspection document according to EN 10204. It certifies the characteristics of the material and reports the results of the tests carried out on the supplied lot. The 3.1 certificate is validated by the manufacturer’s quality department. It is widely used documentation in industrial supplies when it is necessary to demonstrate material conformity with the required specifications.

3.2 certification is documentation according to EN 10204, validated both by the manufacturer and by an independent inspection body. It is required in critical applications, regulated sectors or supplies where the customer needs further verification in addition to 3.1 certification. It is frequent in industrial fields where traceability, material control and independent validation are fundamental requirements.

Magnetic particle testing is a non-destructive inspection method using magnetic particles. It is used to identify surface or subsurface defects on ferromagnetic components. It is a particularly useful test for detecting cracks, discontinuities or defects that are not immediately visible to the naked eye.

Liquid penetrant testing is a non-destructive method used to highlight defects open to the surface of the component. The process uses high-penetration liquids that enter any surface discontinuities, making them visible during the inspection phase. It is a technique used on different materials and components when cracks, porosity or surface defects need to be checked.

Ultrasonic testing uses ultrasonic waves to detect internal defects or discontinuities in the material. It is a non-destructive technique suitable when it is necessary to verify the internal integrity of the component without compromising its use. It may be required for components intended for critical applications or subject to particularly high quality requirements.

Tensile tests are mechanical tests carried out to verify the strength of the material under load. They make it possible to evaluate parameters such as tensile strength, yield strength and material behaviour under stress. They are fundamental tests for confirming the mechanical characteristics of the component and its suitability with respect to the required technical specifications.

Impact tests are used to assess the material’s ability to withstand impact. They are often carried out through Charpy testing and may also be required at low temperatures, when the component must ensure adequate performance in severe environmental conditions. They are important tests for materials intended for applications subject to impact, dynamic stress or low operating temperatures.

The Visual and Dimensional Report documents the visual, dimensional and geometric checks carried out on the component. The inspection is performed against the technical drawing, sample or specifications required by the customer. This report is useful for certifying component conformity in terms of dimensions, geometries, threads, finishes and visual characteristics.

In addition to the most common certifications and inspections, EFS can support specific requests related to technical specifications, sector standards or the customer’s internal procedures. Documentation can be defined during the quotation stage, in order to ensure a supply that is consistent with the project’s technical, quality and documentation requirements.

EFS supports industrial companies, technical departments and quality departments in the management of tests, certifications and inspections on fasteners and fastening components. For specific requests, technical drawings, specifications, technical requirements or indications on the required documentation can be provided.
