Ta tehnična specifikacija določa metodo za zagotavljanje informacij o storitvah in omrežjih v storitvi TPEG. Aplikacija TPEG-SNI je zasnovana za omogočanje učinkovite in jezikovno neodvisne dostave informacij o razpoložljivosti enake storitve na drugem nosilnem kanalu ali podobnih podatkov o storitvah drugega ponudnika storitev, in sicer neposredno od ponudnika storitev do končnih uporabnikov. Izraz »aplikacija« se v specifikacijah TPEG uporablja za opis posebnih aplikacij, ki so na najvišji plasti sklada protokolov ISO/OSI (ISO/IEC 7498-1). Vsaki aplikaciji TPEG (npr. TPEG-RTM) se dodeli enolična številka, tj. identifikacija aplikacije (AID). AID se opredeli ob razvoju nove aplikacije. AID se v aplikaciji TPEG za informacije o storitvah in omrežjih (ta dokument) uporablja za določanje načina obdelave vsebine TPEG in omogoča usmerjanje podatkov v ustrezen aplikacijski odkodirnik. AID = 0000 se dodeli aplikaciji TPEG-SNI, opisani v tej tehnični specifikaciji. Opisanih je več preglednic z informacijami, ki zagotavljajo izčrpne možnosti za opis storitev, njihovega časovnega razporeda, vsebine, geografske pokritosti itn. V vseh tokovih TPEG je obvezna dostava do t. i. GST. Poleg tega je možno signaliziranje povezav vsebine med različnimi nosilci in storitvami.

Introduction Standardized tests for the determination of bactericidal (incl. Legionella pneumophila), mycobactericidal, sporicidal, fungicidal and virucidal (incl. bacteriophages) activity of chemical disinfectants and antiseptics necessitate the use of test organisms whose purity and identity have been verified and whose biological behaviour remains stable. Therefore it is essential to specify the storage requirements.
This European Standard aims at describing methods for preservation of test organisms used for such purposes. SIST EN 12353:2013

1 Scope This European Standard specifies methods for keeping test organisms used and defined in European Standards for the determination of bactericidal (incl. Legionella pneumophila), mycobactericidal, sporicidal, fungicidal and virucidal (incl. bacteriophages) activity of chemical disinfectants and antiseptics drawn up by CEN/TC 216. These methods for keeping test organisms can only be carried out in connection with at least one of those standards where a reference to this European Standard is established. NOTE 1 Annex A (informative) contains a non-exhaustive list of test organisms for which this standard can be applied. NOTE 2 European Standards (EN and prEN) where this European Standard is referenced are listed in the Bibliography. NOTE 3 A specific part on the preservation of bacterial spores may be added once the results of the ongoing ring trials are available. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14885, Chemical disinfectants and antiseptics — Application of European Standards for chemical disinfectants and antiseptics 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14885 apply. 4 Requirements Each test organism specified in a CEN/TC 216 European Standard and referred to in this European Standard shall be handled as described in this European Standard. The purity and identity of the preserved test organism shall be verified during the preparation and regularly during the storage, except for viruses where only the identity is checked before the stock virus suspension is stored. The preserved test organism – except viruses - should be checked at regular intervals (at least in the case of longer storage than 14 months) to ensure that its susceptibility to products has not changed. As long as CEN/TC 216 has not developed specific tests for this purpose any suitable method can be used e.g. EN 1040 for bacteria, EN 1275 for fungi, EN 14348 for mycobacteria, EN 13623 for Legionella pneumophila, EN 14476 for viruses or EN 13610 for dairy bacteriophages. 5 Methods 5.1 Principle A sample of the test organism – in general in freeze dried form - is obtained from a culture collection. This sample is cultured, prepared for storage, filled into storage vessels and placed in the deep freeze.
The origin (culture collection), taxonomic name and reference number, date of receipt and batch number of the freeze dried test organisms shall be recorded (5.11.2). 5.2.2 Culture media and reagents 5.2.2.1 General The formulas of all media and reagents are given in case commercial ready-to-use material is not used. It is to be checked that each commercial supplier has established an appropriate quality control system.
All weights of chemical substances given in this European Standard refer to the anhydrous salts unless otherwise stated. Hydrated forms may be used as an alternative, but the weights required shall be adjusted to allow for consequent molecular weight differences. The reagents shall be of analytical grade and/or appropriate for microbiological purposes. They shall be free from substances that are toxic or inhibitory to the test organisms. To improve reproducibility, it is recommended that whenever possible, commercially available dehydrated material is used for the preparation of culture media. The manufacturer's instructions relating to the preparation of these products should be rigorously followed.
All specified pH values are measured at (20 ± 1) °C. For each culture medium, cell culture and reagent a limitation for use should be fixed. 5.2.2.2 Water The water shall be freshly glass distilled water and not demineralized water. If distilled water of adequate quality is not available, water for injections (see bibliographic reference [1]) can be used. Sterilize in the autoclave (5.3.2.1a)). Sterilization is not necessary if the water is used for e.g. preparation of culture media and subsequently sterilized. 5.2.2.3 Tryptone Soya Broth (TSB) for bacteria, except Legionella Tryptone soya broth, consisting of: Tryptone, pancreatic digest of casein 17,0 g Soya peptone, papaic digest of soybean meal 3,0 g Sodium chloride (NaCl) 5,0 g Water (5.2.2.2) 800,0 ml
Dipotassium phosphate (K2HPO4) 2,5 g Glucose 2,5 g Water (5.2.2.2)
to 1 000,0 ml Sterilize in the autoclave (5.3.2.1a)). After sterilization the pH of the medium shall be equivalent to 7,2 ± 0,2.
