Accreditation is an independent assessment of the competence of a laboratory to produce and/or certify samples or products. Manufacturers all over the world want to be assured that suppliers can deliver their products to the required quality. That is why accreditation is an important aspect in the production of specialty gases. Many of our HiQ® specialty gas facilities have received certification as a producer under ISO 9001 standards and follow additional programmes, such as:
ISO 6141 (requirement for certificates for calibration gas mixtures)
ISO 6142 (preparation of calibration gas mixtures by gravimetric method)
ISO 6143 (comparison methods for determining and checking the composition of calibration gas mixtures)
ISO 6144 (preparation of calibration gas mixtures by volumetric method)
ISO 6976 (specified method for the calculation of the calorific value and the Wobbe index of dry natural gas and other combustible gaseous fuels)
In addition, dedicated Linde specialty gas facilities have received further accreditation to the highest possible standards.
Accreditation - ISO 17025:2005 Testing and/or calibrating laboratory
ISO 17025:2005 specifies the general requirements for the competence to carry out tests and/or calibration, including sampling. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods. It is applicable to all organizations performing tests and/or calibration.
These include, for example, first-, second- and third-party laboratories, and laboratories where testing and/or calibration forms part of inspection and product certification.
Accreditation - ISO Guide 34: 2000 Competence of reference material producers.
Linde Specialty gas facilities in the United Kingdom, Germany, Czech Republic, Australia and Thailand have received accreditation to ISO Guide 34. ISO Guide 34 provides the highest level of quality assurance and allows Linde to confidently state that the methods used to certify their certified reference standards are accurate, consistent, documented and validated.
ISO Guide 34 defines reference materials as substances with a precise composition traceable to the International System of Units (SI) using accurate measurements.
