4 Generalarrangement
4.1 General
The parties concerned or their representatives may be given the opportunity to be present whensamplingis performed.
Whenever special, e.g statutory, requirements are given for the sampling and/or arise from a specificanalysis to be performed, these requirements shall be followed.

They shall be clearly identified.
The minimum details that shall accompany the samples are: the nature of the matrix, its identification,the name or initials of the person responsible for taking the samples, as well as the date, time (ifappropriate), and place of sampling.
This information should be recorded on a form. One form can be used for several samples provided eachhas unique identification and the samples are accompanied by the sampling form which lists the sampledetails with their unique identifying codes.
4.4 Preparation of a sampling form
Samples shall be accompanied by a report, ideally completed on a standard form provided by thelaboratory, signed orinitialled by the sampling personnel.The report shall give the following particulars:
— the place, date and time (if appropriate)of sampling;
— the names of the sampling personnel;
— the nature, number, and identity of samples constituting the consignment;
— the purpose of sampling and the microorganisms to be sought.
When appropriate, the report shall also include any relevant conditions or circumstances, and any special information relating to the product being sampled, e.g. difficulty in achieving representative samples.
If any additives such as diluents, transport media or neutralizing agents are used, these shall be recorded.
5 Diluents and disinfectants
5.1 Diluents.
5.1.1 General. Diluent used for moistening all kind of swabs (bootswabs, stick swabs etc.):
— peptone salt solution prepared according to ISO 6887-1;
— buffered peptone water prepared according to ISO 6887-1;
— sterile water;
— potable water for samples where this would not interfere with the analysis, e.g. bootswabs.
