Sider Test Srl

Sider Test Srl is an independent, ISO 17025 accredited materials testing laboratory founded in 1989 and headquartered in Castel San Giovanni, in the Piacenza province of Emilia-Romagna, Italy. Established to serve manufacturers and engineering companies that process metallic and non-metallic materials, the laboratory has grown over more than three decades into a recognized specialist in both destructive and non-destructive material testing. Sider Test holds Accredia accreditation under UNI EN ISO/IEC 17025 (certificate number 0864), having been among the first Italian laboratories to achieve this certification — a distinction that reflects its long-standing commitment to technical competence, measurement traceability, and internationally recognized test results.

The laboratory's core offering encompasses mechanical testing (prove meccaniche) performed across a wide range of standardized and project-specific methods. Tensile testing is executed to ISO 6892-1 and ASTM A370/E8/E21, delivering yield strength, ultimate tensile strength, elongation at break, and reduction-of-area measurements. Complementary mechanical tests include Brinell, Rockwell, and Vickers hardness testing; Charpy impact testing to ISO 148-1 for fracture toughness and ductile-to-brittle transition evaluation; bend testing; fatigue testing; and compression testing. These capabilities support characterization of steels, stainless steels, cast irons, aluminum alloys, nickel-base superalloys, and non-ferrous metals, as well as composites and polymeric materials.

Chemical analysis (analisi chimiche) at Sider Test covers elemental composition determination for metallic materials and related products. The laboratory applies optical emission spectrometry (OES), X-ray fluorescence (XRF), and complementary wet chemistry methods to identify and quantify alloying elements, trace impurities, and contaminants including carbon, sulfur, phosphorus, nitrogen, and a full suite of metallic and tramp elements. These services underpin incoming material inspection, alloy grade confirmation, supplier qualification, and investigations where off-specification chemistry is suspected as a contributing cause of in-service degradation or failure.

Metallographic examination (esami metallografici) is a flagship discipline of Sider Test. Micro- and macro-metallographic techniques reveal grain structure, inclusion distribution, case and carburizing depth, decarburization layers, weld heat-affected zone (HAZ) characterization, coating and plating thickness, and phase morphology. Grain size measurement is performed per ASTM E112 and ISO 643; inclusion rating follows ASTM E45; and microhardness traverse profiling supports case depth and surface treatment verification. Optical microscopy and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) are available for detailed characterization of fracture surfaces, interface regions, and surface anomalies.

Corrosion testing (prove di corrosione) encompasses a comprehensive set of accelerated and standardized methods for materials qualification and product development. Available techniques include salt spray testing to ISO 9227 and ASTM B117, intergranular corrosion susceptibility assessment per ISO 3651, disbonding tests for coated and clad materials to NACE and ISO standards, and stress corrosion cracking (SCC) evaluation. These services are in particular demand from oil and gas, pipeline, offshore, and petrochemical sector clients — sectors in which Sider Test has developed specific expertise, having participated in energy-industry business forums such as OMC Med Energy.

Non-destructive testing (controlli non distruttivi — NDT) capabilities allow Sider Test to inspect components, weldments, and structural elements without compromising their integrity. Methods include ultrasonic testing (UT), magnetic particle inspection (MPI), liquid penetrant testing (PT), and visual examination, applied to forgings, castings, welds, and fabricated assemblies to detect surface and sub-surface discontinuities. NDT is especially relevant for pressure vessel, structural, and mechanical engineering clients requiring integrity verification before commissioning or after in-service exposure.

Failure analysis (failure analysis) is a high-value consultancy service integrating mechanical, chemical, metallographic, and NDT findings to determine the root cause of component or material failures. The laboratory follows a systematic engineering approach — examining fracture morphology, microstructural anomalies, dimensional deviations, and in-service loading conditions — to deliver technically defensible conclusions suitable for litigation support, warranty disputes, and process improvement. Sider Test also offers heat treatment simulation (simulazione di trattamenti termici), enabling clients to develop, optimize, and validate thermal processing cycles under controlled laboratory conditions before committing to production. Fully customized testing programs are designed to address proprietary standards, research and development requirements, or unique project specifications.

With over 35 years of continuous operation, Accredia ISO 17025 accreditation, and a full-spectrum laboratory covering mechanical, chemical, metallographic, corrosion, non-destructive, and forensic consultancy services, Sider Test Srl is a credible and well-established testing partner for manufacturers, engineering firms, and quality assurance teams across the materials processing, oil and gas, petrochemical, automotive, and mechanical engineering industries. Its location in the industrial heartland of the Piacenza–Emilia-Romagna region of northern Italy provides convenient access for European clients, while its documented accreditation framework ensures internationally recognized and traceable test data.
