Laboratory Quality-Control Practices

PRACTICAL GUIDE

Project context

Practical controls that make test results traceable and defensible. For projects in Afghanistan, early definition of operating conditions, site access, utilities, local skills and maintenance capability helps prevent avoidable procurement changes.

Planning and specification

Written methods, equipment calibration, blanks, duplicates, control samples and review of outliers should form one system. Requirements should be recorded in a clear datasheet and linked to applicable standards, inspection stages, documentation, delivery conditions and acceptance criteria.

Typical equipment and supply scope

Calibration weights, standards, reference materials, LIMS tools, environmental monitors and service kits. The final package should also consider commissioning materials, recommended spares, special tools, training, warranty support and export packing suitable for the complete transport route.

Procurement approach

Comparable bids require one consistent technical scope. Supplier deviations should be listed separately, while drawings, certificates, test reports, country of origin, delivery schedule and after-sales support are evaluated before award.
