This document specifies a horizontal method for the enumeration of coagulase-positive staphylococci by counting the colonies obtained on a solid medium (Baird-Parker medium)[10] after aerobic incubation at 34 °C to 38 °C and coagulase confirmation.
This document is applicable to:
— products intended for human consumption;
— products intended for animal feeding;
— environmental samples in the area of food and feed production, handling, and
— samples from the primary production stage.
This horizontal method was originally developed for the examination of all samples belonging to the food chain.
Because of the large variety of products in the food chain, it is possible that this horizontal method is not appropriate in every detail for all products. Nevertheless, it is expected that the required modifications are minimized so that they do not result in a significant deviation from this horizontal method.
Based on the information available at the time of publication of this document, this method is not considered to be (fully) suited to the examination of fermented products or other products containing technological flora based on Staphylococcus spp (e.g. S. xylosus) (such as cheeses made from raw milk and certain raw meat products) likely to be contaminated by:
— staphylococci forming atypical colonies on a Baird-Parker agar medium;
— background flora that can obscure the colonies being sought.
Nevertheless, both this document and ISO 6888-2 are given equivalent status.

This document specifies a horizontal method for the enumeration of coagulase-positive staphylococci by counting the colonies obtained on a solid medium (rabbit plasma fibrinogen agar medium) after aerobic incubation at 34 °C to 38 °C (see Reference [10]).

— products intended for animal feeding;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.

This document:
— defines a reference Land Administration Domain Model (LADM) covering basic information-related components of land administration/georegulation;
— provides an abstract, conceptual model with packages related to:
— parties (people and organizations);
— basic administrative units, rights, responsibilities, and restrictions;
— spatial units.
— provides terminology for land administration/georegulation, based on various national and international systems, that is as simple as possible in order to be useful in practice. The terminology allows a shared description of different formal or informal practices and procedures in various
jurisdictions;
— provides a platform for indicators-based comparison and monitoring;
— provides a content model independent of encoding, allowing for the support of various encodings;
— provides a basis for national and regional profiles;
— enables the combining of land administration/georegulation information from different sources in a coherent manner.
The following are outside the scope of this document:
— interference with (national) land administration/georegulation laws that may have any legal implications;
— construction of external databases with party data, address data, land cover data, physical utility network data, archive data and taxation data. However, the LADM provides stereotype classes for these data sets to indicate which data set elements the LADM expects from these external sources, if available.
This document provides the concepts and basic structure for standardization in the land administration/georegulation domain. It defines a general schema that permits regulatory information to be described. It also allows for the relationship to multiple parties and groups to be expressed
together with a referencing structure so that sourcing of all information systems may be maintained.
This document establishes the common elements and basic schema upon which more detailed schema may be established. Other parts of ISO 19152 will address specific areas of the land administration paradigm building upon the common core schema defined in document.
