Irrigation equipment - Safety devices for chemigation - Part 1: Small plastics valves for chemigation (ISO 13693-1:2013)

ISO 13693-1:2013 specifies the general requirements and test methods for small plastics-bodied valves used for chemigation, intended for operation in irrigation pipe systems which may contain fertilizers and chemicals of the type and concentration used in agriculture.
It is applicable to controllable safety devices (also known as backflow preventers) with a reduced pressure zone (RPZ), intended to prevent backflow by back-siphonage or backpressure of irrigation water into an upstream potable water distribution system, whenever the pressure in the latter is lower than that in the system located downstream.
It is applicable to such devices of nominal size up to and including DN 50 (2"), with a nominal pressure of PN10, that are capable of working without modification or adjustment at any pressure up to 1 MPa (10 bar), with any pressure variation up to 1 MPa (10 bar), and in permanent duty at temperatures up to 45 °C and for 1 h at 65 °C.

Bewässerungsausrüstung - Sicherheitsvorrichtungen für Beimischungseinrichtungen - Teil 1: Kleine Kunststoffventile für Beimischungseinrichtungen (ISO 13693-1:2013)

Dieser Teil von ISO 13693 legt die allgemeinen Anforderungen und Prüfverfahren für kleine Kunststoff¬ventile zur Verwendung in Beimischungseinrichtungen fest, die im Folgenden als "Vorrichtung" bezeichnet werden und die für den Einsatz in Bewässerungssystemen vorgesehen sind, bei denen Düngemittel und Chemikalien in für die landwirtschaftliche Anwendung üblichen Konzentrationen direkt dem Bewässerungs¬wasser zugegeben werden dürfen.
Er ist anwendbar für regelbare Sicherheitsventile (Rückschlagventile) mit Druckminderer, die den Rückfluss von Bewässerungswasser durch rückläufige Heberwirkung oder Gegendruck in angeschlossene Trinkwasserleitungssysteme verhindern sollen, falls der Druck in der Trinkwasserleitung kleiner als im Bewässerungssystem sein sollte.
Er ist auf Ventile mit Nennweiten bis einschließlich DN 50 (2 inch) mit einem Nenndruck von PN 10 anwendbar, die ohne Modifikation oder Anpassungen
-   bei jedem Druck bis zu 1 MPa (10 bar),
-   bei jeder Druckänderung bis zu 1 MPa (10 bar) und
im Dauerbetrieb bei Temperaturen bis zu 45 °C und für 1 h bei 65 °C betätigt werden können.

Matériel d'irrigation - Dispositifs de sécurité pour l'application de produits chimiques par irrigation - Partie 1: Petites vannes en matière plastique pour l'application de produits chimiques par irrigation (ISO 13693-1:2013)

L'ISO 13693-1:2013 fixe les exigences générales et les méthodes d'essai des petites vannes en matière plastique utilisées pour l'application de produits chimiques par irrigation, par la suite appelées «le dispositif», et prévues pour un fonctionnement dans des systèmes de tuyaux d'irrigation qui peuvent contenir des engrais et des produits chimiques du type et dans une concentration employés dans l'agriculture.
L'ISO 13693-1:2013 est applicable aux dispositifs de sécurité (également appelés disconnecteurs hydrauliques) contrôlables à zone de pression réduite (ZPR), destinés à empêcher les phénomènes de reflux par siphonnement inversé ou par contre-pression de l'eau d'irrigation dans un système amont de distribution d'eau potable chaque fois que la pression dans ce dernier est inférieure à celle qui règne dans le système en aval.
L'ISO 13693-1:2013 est applicable aux dispositifs concernés dont la dimension nominale est inférieure ou égale à DN 50 (2"), avec une pression nominale égale à PN 10 et qui sont capables de fonctionner sans modification ni réglage:
-      à toute pression inférieure ou égale à 1 MPa (10 bar);
-      pour toute variation de pression inférieure ou égale à 1 MPa (10 bar); et
-      en service permanent à des températures inférieures ou égales à 45 °C et pendant 1 h à 65 °C.

Namakalna oprema - Varnostne naprave za dodajanje pesticidov preko namakalnega sistema - 1. del: Mali plastični ventili za dodajanje pesticidov preko namakalnega sistema (ISO 13693-1:2013)

ISO 13693-1:2013 določa splošne zahteve in preskusne metode za male ventile za dodajanje pesticidov prek namakalnega sistema s plastičnim ohišjem za uporabo v namakalnih cevovodnih sistemih, ki lahko vsebujejo vrste in koncentracije gnojil in kemikalij, ki se uporabljajo v kmetijstvu.
Uporablja se za nadzorovane varnostne naprave (poznane tudi kot preprečevalniki povratnega toka) z območjem z zmanjšanim tlakom (RPZ), ki so namenjene za preprečevanje povratnega toka zaradi povratnega vodnega udara ali protitlaka namakalne vode v sistem za porazdelitev pitne vode proti toku, kadar koli je tlak v slednjem nižji od tlaka v sistemu na nižji stopnji toka.
Uporablja se za naprave z nazivno velikostjo največ DN 50 (2 palca) in nazivnim tlakom PN10, ki lahko obratujejo brez spremembe ali prilagoditve na katero koli vrednost tlaka do 1 MPa (10 barov), s kakršno koli spremembo tlaka največ 1 MPa (10 barov) in pri stalnem obratovanju pri temperaturah do 45 °C in za 1 h pri 65 °C.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13693-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture
and forestry, Subcommittee SC 18, Irrigation and drainage equipment and systems.
ISO 13693 consists of the following parts, under the general title Irrigation equipment — Safety devices
for chemigation:
— Part 1: Small plastics valves for chemigation
Chemigation valve assemblies from DN 75 to DN 350 are to form the subject of a future part 2.
