SATRA Technology Centre

SATRA Technology Centre is an independent research, testing, and certification organisation founded in 1919 and headquartered at Rockingham Road, Kettering, Northamptonshire, UK. Originally established as the Shoe and Allied Trades Research Association, SATRA has grown over more than a century into one of the world's leading technical partners for the footwear, leather goods, personal protective equipment (PPE), furniture, and consumer products industries. With facilities spanning the United Kingdom, Europe, and China, and a team of over 180 scientific, technical, and support staff, the organisation provides testing, product certification, research, standards development, and training services to manufacturers, brands, retailers, and supply-chain partners worldwide.

Footwear testing is one of SATRA's most well-developed areas of expertise. The laboratory evaluates footwear across every category — from safety and occupational boots to sports shoes, children's footwear, and high-fashion designs — against European and international standards. Core standards applied include EN ISO 20345 for safety footwear, EN ISO 20346 for protective footwear, and EN ISO 20347 for occupational footwear, as well as bespoke test methods developed in-house that are unavailable elsewhere. Physical durability assessments cover outsole adhesion, upper flex resistance, heel impact absorption, slip resistance, and stitch strength. Chemical analyses performed on footwear materials include testing for restricted substances under EU REACH, azo dyes, chromium VI in leather components, phthalates, and heavy metals, supporting compliance with European and US regulatory frameworks.

SATRA holds significant standing in the PPE sector as both a test laboratory and a certification body. The organisation is a Notified Body (NB 2777) recognised by the European Commission under the PPE Regulation (EU) 2016/425, and an Approved Body (0321) in Great Britain under the UK PPE regulations, enabling it to issue EU type-examination certificates and UKCA conformity marks directly. PPE testing spans a wide range of product types and protective performance categories. Protective gloves are tested to EN 388 (resistance to mechanical risks), the EN ISO 374 series (protection against chemicals and micro-organisms), EN 21420 (general requirements and test methods), EN ISO 374-6 (protective gloves for hairdressers), and EN 407 (protection against heat and fire). The laboratory also evaluates protective footwear, eye and face protection, head protection, and body protection garments for CE and UKCA markets, and for American, Chinese, and other international standards.

Chemical and restricted-substance testing forms another core service pillar at SATRA. The laboratory operates a dedicated chemicals analysis division staffed by expert chemists and equipped with sophisticated analytical instrumentation for detecting hazardous substances in footwear, leather goods, textiles, PPE, and furniture. Testing encompasses REACH Annex XVII restricted substances, Substances of Very High Concern (SVHC) under REACH Annex XV, harmful azo dyes in textile and leather articles, heavy metals including hexavalent chromium, lead, cadmium, and nickel, phthalates in polymer components, and formaldehyde in finished products. SATRA is also accredited by the US Consumer Product Safety Commission (CPSC) for testing to US market chemical requirements, enabling manufacturers targeting North American retailers to obtain compliant results from a single laboratory engagement.

Leather goods and materials testing is deeply integrated into SATRA's heritage and capabilities. The laboratory evaluates the physical, mechanical, and chemical properties of full-grain, corrected-grain, split, and synthetic leathers, as well as coated fabrics, rubber compounds, textile substrates, and polymer films used across footwear and leather goods supply chains. Performance tests include tensile strength, tear resistance, elongation, colour fastness, rub fastness, water resistance, water vapour permeability, and flex cracking resistance, all conducted in modern temperature- and humidity-controlled environments. These capabilities serve tanneries, component suppliers, brand quality-assurance teams, and importers seeking to benchmark or validate material specifications against procurement standards.

Furniture testing is an established secondary specialism at SATRA, serving UK and European upholstered furniture manufacturers, fabric suppliers, and retailers. The laboratory carries out flammability testing to the UK Furniture and Furnishings (Fire) (Safety) Regulations 1988, covering upholstered seat furniture, bed bases, headboards, pillows, and scatter cushions. Durability and structural integrity testing for seating, storage, and casegoods is performed to relevant EN and BS standards, complementing the chemical and restricted-substance testing applicable to furniture surface materials and component fillings.

SATRA's accreditation framework provides a strong and independently verified quality foundation. The laboratory is accredited by the United Kingdom Accreditation Service (UKAS) to ISO/IEC 17025 with flexible scope — a status that permits the addition of new test methods to its accreditation schedule without requiring individual UKAS re-assessments, reflecting exceptional confidence in SATRA's quality management system. In parallel, SATRA holds ISO/IEC 17065 accreditation for product certification activities, underpinning its CE and UKCA marking services. Beyond its own accreditation, SATRA administers the QS 1000 Laboratory Accreditation programme, an internationally recognised third-party scheme through which it formally accredits other footwear and leather goods test laboratories around the world.

In addition to testing and certification, SATRA develops, manufactures, and commercially distributes its own proprietary test equipment, used in footwear and materials laboratories across the globe. The organisation plays an active role in national and international standards committees, with staff chairing BSI and ISO working groups responsible for key footwear and PPE standards. Training programmes — including the internationally recognised SAFT (SATRA Award for Footwear Technology) qualification, online footwear foundations courses, in-person laboratory open days, and technical webinars on topics from glove performance to laboratory accreditation — are offered regularly to members and the broader industry. Membership of SATRA provides access to laboratory services at preferential rates, technical publications, an online knowledge base, and participation in industry forums, making SATRA a uniquely comprehensive partner across the full lifecycle of product development, compliance, and market access.
