Fatty food - Determination of pesticides and polychlorinated biphenyls (PCBs) - Part 2: Extraction of fat, pesticides and PCBs, and determination of fat content
Scope: This part of prEN 1528 specifies a range of analytical procedures for extractingthe fat portion containing the pesticide and PCB residues from different groups of fat-containing foodstuffs.
Base documents: EN 1528-2:1996
EVS-EN 1528-3:2000
Fatty food - Determination of pesticides and polychlorinated biphenyls (PCBs) - Part 3: Clean-up methods
Scope: This part of EN 1528 specifies the details of methods A to H for the clean-up of fats and oils or the isolated fat portion, respectively, using techniques such as liquid/liquid partition, adsorption or gel permeation column chromatography. The applicable usage of the methods A to H is given in detail ineach method described. Note: See also prEN 1528-4 which lists a clean-up procedure for the removal of the bulk of lipids when analysing large quantities of fat.

Fatty food - Determination of pesticides and polychlorinated biphenyls (PCBs) - Part 4: Determination, confirmatory tests, miscellaneous
Scope: This part of prEN 1528:1994 specifies some recommended techniques for the determination of pesticides and PCBs in fatty foodstuffs, confirmation of results and an additional clean-up procedure.

Milk - Enumeration of somatic cells - Part 1: Microscopic method (Reference method) (ISO/DIS 13366-1:2026)
Scope: This document specifies a microscopic method (reference method) for the counting of somatic cells in both raw and chemically preserved milk. This document 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 values that are required for calibrating mechanized and automated cell-counting methods.

Milk - Enumeration of somatic cells - Part 2: Flow cytometry method (ISO/DIS 13366-2:2026)
Scope: This document gives guidance on the operating conditions for counting the total number of somatic cells, in both raw and chemically preserved milk, using flow cytometers.
The guidance is applicable to the counting of somatic cells in raw cow milk. The guidance is also applicable to raw milk of other species, such as goat, sheep and buffalo, if the specified prerequisites are met.
