ISO 9001 is the world’s most recognised quality management system standard, established by the International Organisation for Standardization (ISO). First certified in 2020, Petrolab has since been recertified to October 2024. This certification represents complying with the standards for customer-focused quality management with a focus on continuous improvement. Petrolab are proud of this achievement and it’s focus on listening to client feedback and at the end increasing the quality of our output and the satisfaction of our customers.
The Nevada Division of Environmental Protection (NDEP) is the regulatory body the oversees the preservation and enhancement of the environment of the state in order to protect public health, sustain healthy ecosystems and contribute to a vibrant economy. Since 2020 Petrolab has been certified to work within the State for fully automated and semi-automated SEM-EDX analysis. Petrolab was recently recertified until 2024 for this analysis and as of 2023 is now certified for XRD analysis. Petrolab is proud of these achievements and its recognition of the quality management system that we have in place for these critical analytical tools.
Petrography is a diverse discipline covering the analysis of multiple materials from geomaterials (e.g. concrete, mortar, industrial products), to original quarried rock destined for various end purposes (e.g. aggregate, slate and stone) to multiple applications in the mining industry (automated mineralogy, exploration and paragenesis studies). As petrography is an integral part of the analysis of all these materials Petrolab offers internal recognition of competency in petrography based on years of experience (at least 5), training, separate recognition by another Competent Petrographer and example reports held within a personal portfolio. All work undertaken for Clients is led by staff (either directly or through technical review) who are considered Competent in the field in question.
