Testing labs in Heol Klockner

Rhymney Test Equipment LTD is an independent, UKAS-accredited environmental testing and calibration laboratory headquartered at Unit 19, Heads of the Valley Industrial Estate, Rhymney, Tredegar, Wales (NP22 5RL). Incorporated in July 2020, the company holds accreditation to BS EN ISO/IEC 17025 for testing and is also certified to ISO 9001 for its quality management system. The laboratory operates Monday to Friday, 07:00–17:00, and serves a diverse base of product manufacturers, engineers, and quality teams who need their goods formally assessed against recognised environmental performance standards. The company's principal offering is environmental testing — a discipline that subjects products and materials to simulated climatic and mechanical stresses in order to reveal design weaknesses, confirm performance at extremes, or satisfy regulatory and customer requirements. Environmental testing uses controlled-environment chambers to replicate the conditions a product will face during its working lifetime or in the supply chain, and the resulting test records document how the product responds to those conditions. Rhymney Test Equipment maintains a range of accredited test chambers capable of reproducing a wide spectrum of environmental conditions. The laboratory's accredited test repertoire covers temperature testing, humidity testing, thermal shock testing, temperature cycling, climatic testing, corrosion testing, and transport simulation. Life testing and accelerated life testing are also offered, enabling customers to condense years of anticipated field exposure into controlled, time-compressed trials. Production-monitoring programmes can be configured to give ongoing assurance that manufactured goods continue to meet the agreed environmental performance baseline, while testing during design and development helps engineering teams identify and eliminate failure modes before a product reaches market. In addition to in-house laboratory testing, Rhymney Test Equipment provides on-site calibration services for environmental test chambers already installed at customer facilities. Using UKAS-calibrated reference equipment, the company's engineers travel to client sites to carry out temperature and humidity mapping and calibration of climatic chambers, qualifying the performance of those chambers and generating the traceable records needed to maintain a customer's own quality system. This service is particularly valuable for manufacturers who operate their own environmental chambers and must demonstrate calibration traceability as part of ISO or customer audit requirements. Rhymney Test Equipment acts as the authorised European and UK sales agent for Xi'an LIB Environmental Simulation Industries, enabling it to supply both standard and fully bespoke climatic chambers across the UK and Europe. The company also holds a stock of second-hand and refurbished environmental chambers available for outright purchase, providing a cost-effective route for organisations that need in-house test capability. For customers who require periodic or project-specific access to environmental chambers without the capital commitment of ownership, the laboratory offers a chamber hire service; chambers are available for minimum three-month rental periods, and in some cases customers may conduct testing directly at Rhymney's own facility on equipment that cannot be relocated. A sister company, SJJ System Services, complements the group's offering by specialising in the maintenance and servicing of ultra-low temperature chambers operating down to −80 °C and below, covering units ranging from 50 to 1,000 litres and supporting brands including Brunswick, Binder, Sanyo, and Panasonic. This relationship means the wider group can support customers maintaining deep-cold or cryogenic simulation chambers alongside conventional climatic test equipment, making it a more comprehensive environmental test partner. Accreditation to BS EN ISO/IEC 17025 — the internationally recognised standard for the competence of testing and calibration laboratories — is the cornerstone of Rhymney Test Equipment's quality framework. UKAS oversight means the laboratory's technical competence, measurement traceability, and reporting practices are regularly assessed by an independent, government-appointed body. ISO 9001 certification provides a complementary quality management layer covering overall business processes. Together, these accreditations give customers confidence that test results are technically sound, traceable, and defensible for use in product approval documentation, regulatory submissions, safety cases, or supply chain audits. Rhymney Test Equipment is positioned as a flexible, independent partner for any organisation that needs access to accredited environmental testing without the overhead of owning and maintaining a fully equipped in-house laboratory. Whether the requirement is a one-off standards compliance run, an ongoing production-monitoring programme, calibration of existing chambers, or guidance on selecting and procuring new test equipment, the company's combination of accredited laboratory testing, on-site calibration capability, chamber sales expertise, and hire inventory makes it a broadly capable single source for environmental test support in the UK.
