This standard applies to processed products of fruits and vegetables and establishes a photometric method for the determination of nitrates. The standard does not apply to dried foods and food from potatoes. The method consists in the extraction of nitrates from the product, their reduction to nitrites on a cadmium column, photometry of the azo compound solution resulting from the interaction of nitrites with aromatic amines and recalculation of the found amount of nitrites to nitrates taking into account the nitrites contained in the product. The requirements of this standard are mandatory. 1. Sampling and preparation of samples 2. Apparatus, materials, reagents 3. Preparation for testing 4. Conducting a test 5. Processing results 6. Requirements of safety measures during testing
