The standard applies a global factor of safety built from multiple sub-factors (K-factors). These account for: Method of manufacture (hand lay-up vs. filament winding) Chemical environment and corrosion allowances Operating temperature and thermal degradation Long-term creep and fatigue under sustained load 4. Testing and Quality Control

BS 4994 uses "unit properties" (force per unit width per layer of reinforcement, e.g., N/mm per kg/m² of glass) instead of standard stress units (N/mm²). This accommodates the variable thickness of handmade composite laminates, ensuring structural calculations rely strictly on the amount of glass fiber reinforcement present. 4.
