Skip to content Our textile testing laboratory operates as a specialized scientific facility that verifies the physical, mechanical, chemical, and dimensional properties of fibers, yarns, fabrics, and finished garments through standardized test protocols. By conditioning samples in controlled standard atmospheres and subjecting them to calibrated analytical instrumentation, a textile testing laboratory evaluates material performance against national and international regulatory thresholds before commercial shipment.

As Pakistan’s trusted technical evaluation partner, SAB Labs provides a one-stop solution covering accredited testing and third-party inspection services to guarantee full export compliance for regional textile mills.
Partnering with an accredited textile testing laboratory provides manufacturers and exporters with three primary benefits:
A modern testing laboratory comprises four essential technical divisions:
These represent the essential baseline testing services required by textile mills, spinning units, and apparel exporters at every stage from raw fiber to finished garments:
Mandatory regulatory and ecological screening to clear international customs and satisfy EU/US buyer Restricted Substances Lists (RSL):
Factory audits, auxiliary component verification, and export packaging testing required by international buyers:
Compliance verification enables frictionless international customs clearance and eliminates the threat of buyer chargebacks, shipment rejections, or port detentions.
Exporters shipping goods to international markets must meet the specific standard authorized by the purchasing territory. SAB Labs aligns its testing protocols with American (AATCC/ASTM), International (ISO), British (BS), German (DIN), and Chinese (GB) requirements. Testing instruments, load cells, and bath temperatures adapt strictly to the explicit procedural requirements of each standard.
SAB Labs screens raw materials, input chemicals, dyestuffs, and finished textiles against the industry’s most stringent chemical restrictions:
SAB Labs provides independent inspection and verification services across industrial manufacturing hubs in Pakistan to verify product quantity, packaging, labeling, and craftsmanship before export dispatch.
Pre-production inspection prevents defective inputs from entering commercial cutting lines. Quality auditors inspect greige and processed fabric rolls using the international 4-Point System (ASTM D5430) to evaluate weaving flaws, yarn slubs, barre, hole defects, and color shading variations across roll width.
Trims, interlinings, sewing threads, zippers, and care labels undergo rigorous status check inspections to confirm shade matching under standardized D65 lighting booths, tensile stability, and dimensional compatibility before cutting begins.
During Production Inspection (DUPRO) takes place when 15% to 40% of the production order is completed. SAB Labs inspectors assess semi-finished and finished units on the sewing lines to detect:
Defect analysis provides immediate root-cause feedback to factory floor managers, allowing operational corrections before defective lots accumulate.
Final Random Inspection (FRI) occurs when an order is 100% produced and at least 80% packaged in export master cartons. Quality auditors draw statistical sample quantities based on the internationally recognized ISO 2859-1 (ANSI/ASQ Z1.4) sampling tables using Acceptance Quality Limit (AQL) standards—typically AQL 1.5 for critical defects, AQL 2.5 for major defects, and AQL 4.0 for minor defects.
Inspections include carton drop tests, gross and net weight verification, barcode scan readability checks, polybag suffocating warning label audits, and export container supervision of loading to safeguard shipment integrity.
SAB Labs delivers reliable textile testing with accredited facilities, calibrated equipment, fast turnaround, and verified test reports. Manufacturers and exporters can rely on accurate results for quality control, compliance, and buyer requirements.
SAB Labs is accredited by PNAC under laboratory reference LAB-185, demonstrating technical competence, reliable test methods, calibrated equipment, and controlled laboratory procedures.
Testing is performed using calibrated laboratory equipment and controlled atmospheric conditions to maintain accuracy and consistency across physical and chemical textile tests.
Receive certified test reports within 3–5 business days. Same-day express testing is also available, with results delivered within 12–24 hours for urgent production, audit, or export requirements.
SAB Labs test certificates include digital QR-code verification, allowing buyers and sourcing teams to quickly verify report authenticity and access certificate details online.
