The British Standards Institute was established in 1901 and incorporated by Royal Charter in 1929. Its mission then, as now, is to protect consumer and supplier interests through a wide range of quality and inspection services. BSI operates in over 90 countries developing standards and specifications, systems assessments, product testing, product certification and materials inspection.

BSI have over this period evolved the Kite Mark scheme that has achieved recognition as the premier international quality seal of approval. Sternfenster is proud of its association with BSI and will continue to strive to meet the high quality standards required.
