Testing labs in Castellón de la Plana

3 SERCAL, S.L., trading under the brand SC Laboratorio de Calibración (and commercially as SC Servicios Tecnológicos), is an independent calibration and metrology laboratory headquartered in Castellón de la Plana, Spain. Founded in 2006 and operating from its facility at C/ Amalia Abad Pastor, Nº 1, Polígono Industrial la Basala, the laboratory has built close to two decades of experience providing precision measurement and calibration services to industrial clients across Spain and Portugal. The company operates with a small, highly qualified team dedicated to ensuring that customers' measurement and test equipment performs within specified tolerances, thereby helping those clients satisfy the requirements of quality certifications and regulatory audits. The laboratory's core offering is the calibration of a broad range of measurement magnitudes and the instruments that measure them. In the area of mass (masa), SC Laboratorio calibrates single-pan balances and precision scales of all capacities, a scope for which the laboratory holds formal accreditation. In the electrical domain, it calibrates data loggers, ammeters, voltmeters, multimeters, and process calibrators. For temperature, the laboratory handles thermometers, temperature probes, industrial ovens, climatic and thermal chambers, and infrared pyrometers. Dimensional and length calibration covers dial indicators, Vernier calipers, micrometers, and gauge blocks (patrones de longitud), while pressure calibration extends to manometers, pressure transducers, and pressure transmitters. Beyond those primary areas, the laboratory also calibrates force gauges, torque wrenches, and hydraulic presses in the force domain, as well as thermocouples, Pt100 resistance temperature detectors (RTDs), and industrial transmitters in the instrumentation domain. Additional measurement instruments serviced include gas analyzers, lux meters, viscometers, pH meters, and conductivity meters — a breadth that reflects the diverse analytical needs of its client base. All calibration work is performed in compliance with a quality management system founded on UNE-EN ISO/IEC 17025, with uncertainty calculations following the ENAC guidance document EA-4/02 M:2010, and procedures aligned with the methodology established by Spain's Centro Español de Metrología (CEM). SC Laboratorio de Calibración holds accreditation from ENAC (Entidad Nacional de Acreditación), Spain's national accreditation body and the country's single multilateral recognition signatory under the EA (European co-operation for Accreditation) and ILAC frameworks. The laboratory's ENAC accreditation under ISO/IEC 17025 for the mass area — covering single-pan balances and scales — has been in force since April 2009, establishing its long-standing competence in metrological traceability. Non-accredited calibrations performed by the laboratory are nonetheless conducted under the same ISO/IEC 17025-based quality management system, giving clients a consistent standard of reliability across all service areas. Staff qualifications, supervision, and periodic recertification follow the personnel competence requirements set out in ISO/IEC 17025. The laboratory serves a notably diverse set of industrial sectors, with a particularly strong presence in the ceramics and building-materials industries of the Valencia Region — one of Spain's most concentrated manufacturing hubs for ceramic tiles and construction products. Documented clients include internationally recognised tile brands such as Grespania, Porcelanosa, Pamesa, Vives, and Marazzi, as well as construction materials suppliers Kerakol and Macer, and chemical-products manufacturer Quimialmel. Beyond ceramics and construction, SC Laboratorio serves food and alimentary-sector companies, pharmaceutical and chemical-process industries, and general manufacturing clients throughout Spain and, to a growing extent, Portugal. Service delivery is designed around speed and convenience. The laboratory offers both in-house calibration at its Castellón facility and on-site calibration at the client's premises, minimising equipment downtime and reducing logistical complexity for plant managers. Calibration certificates are typically issued and delivered digitally via a secure client portal within one week of the service date. The laboratory also offers customised training sessions in metrology and calibration practice, helping client quality teams build internal competence and better manage their calibration programmes in accordance with ISO 9001, IATF 16949, and other sector-specific management system standards. As a member of the Red de Laboratorios de la Macaronesia (Macaronesia Laboratory Network), SC Laboratorio de Calibración extends its reach beyond mainland Spain, offering its calibration expertise to clients in the Canary Islands and other Atlantic island territories where access to accredited metrology services can otherwise be limited. The laboratory has additionally benefited from EU NextGenerationEU funding to modernise instrumentation and strengthen its quality infrastructure. For manufacturers, food processors, tile producers, and chemical companies whose ISO or customer audits demand demonstrably traceable, independently verified measurement data, 3 SERCAL, S.L. offers a regionally established, ENAC-accredited partner with the responsiveness and technical depth that larger national providers often cannot match at the local level.

The Instituto de Tecnología Cerámica (ITC), managed under the Asociación de Investigación de las Industrias Cerámicas (AICE), is one of Europe's leading technology centers and accredited testing laboratories serving the ceramics and advanced-materials industries. Established in 1969 as a joint institute between AICE and the Universitat Jaume I de Castellón de la Plana (UJI), ITC is headquartered at the UJI campus in Castellón, Spain, with an additional branch facility in Almassora (Polígono Industrial Supoi-8)—the heart of Europe's most concentrated ceramic tile manufacturing cluster. With more than five decades of continuous activity, ITC is recognized internationally as a benchmark testing, certification, and research partner for ceramic manufacturers, raw-material suppliers, equipment makers, and regulatory bodies across Spain and beyond. ITC holds ENAC (Entidad Nacional de Acreditación, Spain's national accreditation body) accreditation under UNE-EN ISO/IEC 17025, with accreditation number 2/LE004 (current revision Edition Nº 29, dated 12 July 2024). Uninterrupted ENAC accreditation has been maintained since 1988, covering a scope of testing across ceramic tiles, sanitary ware, bathtubs, structural ceramics, flooring, and related construction materials. This long-standing accreditation positions ITC among the most credible independent testing authorities in the European ceramics sector, enabling it to issue test reports recognized by international buyers, certification bodies, and regulatory authorities. The institute's testing portfolio comprises more than 475 distinct test methods. For ceramic tiles, ITC performs the full suite of physical, mechanical, and chemical tests prescribed by the UNE-EN ISO 10545 standard series, including dimensional conformance (ITC is the only ENAC-accredited laboratory in Spain capable of dimensional testing under UNE-EN ISO 10545-2 for tiles up to 3 meters in length), water absorption, breaking strength, modulus of rupture, thermal shock resistance, frost resistance, slip resistance, surface and deep abrasion, chemical resistance, stain resistance, coefficient of thermal linear expansion (UNE-EN ISO 10545-18, unique in Spain), and determination of small colour differences (UNE-EN ISO 10545-16, also exclusive to ITC in Spain). ITC is the only laboratory in Spain able to perform all tests required for the French QB-UPEC and QB-WallPEC ceramic tile quality marks. In sanitary ware and bathroom equipment, ITC is the only ENAC-accredited laboratory in Spain for testing toilets, bidets, shower trays, and bathtubs, and was the national pioneer in offering third-party certification for these product categories. Testing covers dimensional verification, structural load-bearing and strength performance, water tightness, glaze surface quality, and compliance with applicable European and national standards. For construction ceramics such as clay roofing tiles and structural masonry products, ITC similarly holds accreditation for standardization tests under UNE-EN 13004 and related specifications. Beyond finished-product characterization, ITC operates advanced analytical chemistry and materials science laboratories capable of chemical analysis of solid, liquid, and gas samples from ppb detection levels upward. Instrumental techniques include scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS) for surface and microstructural defect analysis, X-ray photoelectron spectroscopy (XPS) for compositional analysis of nanometric layers, X-ray diffraction (XRD) for phase identification, and a broad range of spectroscopic and chromatographic methods. These capabilities enable comprehensive chemical characterization of ceramic bodies, glazes, frits, engobes, and raw materials such as feldspar, kaolin, and ball clay, as well as composites, glasses, metals, and carbonaceous materials. The laboratory also performs food-contact suitability testing of ceramic articles and packaging materials, including migration testing for potentially hazardous substances. ITC operates the only ENAC-accredited capability in Spain for measuring the nitrogen oxide (NOx) elimination performance of photocatalytic materials under ISO 22197-1:2016 and UNE 127197-1:2013, supporting the expanding market for air-purifying ceramic products used in urban and architectural applications. Additionally, the institute conducts industrial hygiene measurements that are unique in Spain, including accredited determination of respirable dust and crystalline silica (quartz and cristobalite) fractions in workplace air—a critical service for ceramic manufacturing facilities operating under European Directive 2017/164/EU worker health requirements. ITC's research and applied-services activities are organized into thematic knowledge areas: advanced materials, decarbonization of industrial processes, digital transformation of manufacturing, circular economy and waste valorization, sustainable and green chemistry, environmental health, urban solutions with ceramic materials, and computational modeling and simulation. The institute operates a fully equipped ceramic-processing pilot plant with grinding, drying, forming (pressing and extrusion), and kiln-firing capabilities that replicate real industrial conditions at reduced scale, enabling process optimization studies, new-product development trials, and systematic quality troubleshooting. These capabilities, combined with an exceptionally broad accredited testing scope, decades of specialized sector expertise, and formal alignment with ESG (environmental, social, and governance) criteria, make ITC a uniquely comprehensive testing and technology partner for any organization operating in the global ceramics, construction materials, and advanced-materials supply chain.
