适用范围：This International Standard specifies an atomic absorption spectrometric method for the determination of the tin content of fruit and vegetable products in the concentration range 10 mg/kg to 500 mg/kg. It is a rapid method, especially suitable for routine determinations of tin in canned fruits and vegetables contaminated with tin which has migrated from the can. The method can be applied with the prescribed amount of sample to products with a maximum total dry matter content of 30 %. Products with higher contents of total solids can be analysed using smaller amounts of sample after corresponding dilution with deionized water. NOTE The method of tin determination in fruit and vegetables products is based on NMKL method No 126/1988 (reference [1] in Annex A).
