1a237a,—,Potassium diformate,     Additive composition       Potassium diformate: 50 ± 5 %,      Water: 50 ± 5 %.         Characterisation of the active substance     Potassium diformate    CAS No 20642-05-1    C 2 H 3 O 4 K    Produced by chemical synthesis       Method of Analysis        Determination of potassium in the feed additive:    EN ISO 6869: atomic absorption spectrometry (AAS) or EN 15510: inductively coupled plasma atomic emission spectrometry (ICP-AES)      Determination of total formate in the feed additive: EN 15909: reverse phase HPLC-UV    For the determination of total formate in premixtures and feedingstuffs:    Ion-exclusion high performance liquid chromatography with UV or refractive index detection (HPLC-UV/RI) or ion chromatography method equipped with electrical conductivity detection (IC-ECD).      ,All animal species,—,—,—,  1.   Only permitted in raw fish and fish by-products for feed use with a maximum content of 9 000 mg potassium diformate as active substance per kg raw fish.     2.   For use in feed for pigs, the mixture of different sources of potassium diformate shall not exceed the permitted maximum level in complete feedingstuff of 18 000 mg per kg complete feedingstuff for weaned piglets and 12 000 mg per kg complete feedingstuff for sows and pigs for fattening.     3.  Indicate in the instructions for use:     The simultaneous use of other organic acids at the maximum permitted doses is contraindicated    .     4.     For safety: breathing protection, eye protection and gloves shall be used during handling    .   ,11 May 2022,
