What size specimen is tested in a SBI test?
Each specimen is constructed from a “short wing” and a “long wing”. The long wing is 1500mm high by 1000mm wide. The short wing is 1500mm high by 495mm wide. All tolerances are ± 5mm. A minimum of 3 specimens are required. Further specimens may be required if a product produces a result on the border line between two classification and the higher classification is sought. Further specimens may also be required for testing of variations in the product.
