We plan, organise and analyse interlaboratory comparison rounds, and supply certified reference materials with assigned values — helping laboratories raise testing competence and data credibility.
From scheme design to data analysis — a single service that keeps your proficiency testing programme compliant, credible and sustainable.
Defining test items, parameters, reference standards and the participating laboratory scope
Homogeneity-verified samples, supplied with a homogeneity report and assigned values
Samples shipped to all participating laboratories at the same time, under identical conditions
Results gathered from each laboratory and entered into a single processing platform
Z-scores, performance indices and outlier detection, compiled into an assessment report
Proficiency testing programmes tailored to each laboratory, covering mechanical, thermal, chemical and other test parameters.
Objective, impartial performance assessment of every laboratory using internationally accepted statistical methods.
Reference materials with traceable assigned values, calibrated by an authoritative body, for internal quality control and instrument calibration.
Homogeneity-verified and value-assigned under a strict procedure; every batch ships with its own certificate and uncertainty data.
Certified reference material (CRM) is an essential tool for laboratory quality control and a key basis for instrument calibration and method validation.
Our materials go through:
Each batch ships with a printed and an electronic certificate stating the assigned parameters, measurement conditions, uncertainty and validity period.
30% glass-fibre reinforced polypropylene density reference material, for validating density methods and calibrating instruments.
30% glass-fibre reinforced polypropylene tensile modulus reference material, for validating tensile methods and proficiency comparison.
30% glass-fibre reinforced polypropylene flexural modulus reference material, for validating flexural methods and calibrating instruments.
30% glass-fibre reinforced polypropylene notched impact reference material, for validating impact methods and proficiency comparison.
High-toughness PP/EPDM blend impact reference material, for validating impact methods on high-toughness materials.
Grey ABS heat deflection temperature reference material, for validating HDT methods and calibrating equipment.
Every report is rigorously reviewed — standardised format, transparent data, compliant with CNAS accreditation and ISO/IEC 17043.
Each comparison round comes with a complete analysis report containing raw data, statistical results, performance assessment and improvement recommendations.

Scheme design, sample preparation, data analysis and reporting completed in one place — no coordination across multiple parties.
Reports follow ISO/IEC 17043 and CNAS-CL03 requirements and are recognised by the commissioning OEM.
ISO 13528 methods with Z-scores, En numbers, robust statistics and other assessment systems.
30+ grades of certified reference material covering plastics, rubber and metals, each with a CNAS certificate.
