ISO 488 | IDF 105: 2008 – Milk – Determination of fat content – Gerber butyrometers
This standard specifies the characteristics of seven types of butyrometer for use in the determination of the fat content of whole milk, partly skimmed milk and skimmed milk by the Gerber method specified in ISO 2446. ISO 488 | IDF 105:2008 is withdrawn and replaced with ISO 19662 | IDF 238:2018
ISO 1737 | IDF 13: 2008 – Evaporated milk and sweetened condensed milk – Determination of fat content – Gravimetric method (Reference method)
Withdrawn and replaced by the joint standard ISO 23318 | IDF 249: 2022
ISO 1736 | IDF 9: 2008 – Dried milk and dried milk products – Determination of fat content – Gravimetric method (Reference method)
Withdrawn and replaced by the joint IDF/ISO standard ISO 23318 | IDF 249: 2022
ISO 13366-1 | IDF 148-1: 2008 / COR 1: 2009 – Milk – Enumeration of somatic cells – Part 1: Microscopic method (Reference method) / Technical Corrigendum 1
This standard specifies a microscopic method (reference method) for the counting of somatic cells in both raw and chemically preserved milk. This standard is applicable for the counting of somatic cells in cows’ milk, provided that the eventually mentioned prerequisites are met. This method is suitable for preparing standard test samples and determining reference method […]
ISO 9231 | IDF 139: 2008 – Milk and milk products – Determination of the benzoic and sorbic acid contents
This standard specifies a method for the determination of the benzoic and sorbic acid contents in milk and milk products. The method is applicable to milk, dried milk, yogurt and other fermented milks, and cheese and processed cheese, and is suitable for measuring the contents of both compounds at levels of more than 5 mg/kg.
ISO 8260 | IDF 130: 2008 – Milk and milk products – Determination of organochlorine pesticides and polychlorobiphenyls
Method using capillary gas-liquid chromatography with electron-capture detection This standard specifies a method for the determination of the contents of individual organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in milk, evaporated milk, sweetened condensed milk, powdered milk products, butter and butterfat, cheese and other milk products. The method is capable of determining low levels of […]
ISO 2446 | IDF 226: 2008 – Milk – Determination of fat content
This standard specifies a routine method (the Gerber method) for the determination of the fat content of milk and includes guidance on the determination of the appropriate capacity of the milk pipette and on the determination of the corrections to apply to the results if the milk is not of average fat content. The procedure […]
ISO 20541 | IDF 197: 2008 – Milk and milk products – Determination of nitrate content – Method by enzymatic reduction and molecular-absorption spectrometry after Griess reaction
This standard specifies a method for the determination of the nitrate content of milk and milk products by molecular-absorption spectrometry after Griess reaction (preceded by enzymatic reduction). The method is, in particular, applicable to whole, partly skimmed, skimmed and dried milk, hard, semi-hard and soft cheeses, processed cheese, whey cheese, caseins, caseinates, dried whey and […]
ISO 3433 | IDF 222: 2008 – Cheese – Determination of fat content – Van Gulik method
This standard specifies the Van Gulik method for the determination of the fat content, as a mass fraction, of cheese. This method is applicable to all types of cheese. However, it may not give completely satisfactory results when applied to cheeses with an internal mould (blue-veined cheeses).
ISO 3432 | IDF 221: 2008 – Cheese – Determination of fat content – Butyrometer for Van Gulik method
This standard specifies the characteristics of a butyrometer (including stoppers) for the determination of the fat content, in the range 0 % mass fraction to 40 % mass fraction, of cheese by the Van Gulik method and illustrates suitable devices for weighing and introducing the cheese test portion.
