Solar energy - Solar thermal collectors - Test methods (ISO 9806:2017)

This document specifies test methods for assessing the durability, reliability, safety and thermal
performance of fluid heating solar collectors. The test methods are applicable for laboratory testing
and for in situ testing.
This document is applicable to all types of fluid heating solar collectors, air heating solar collectors,
hybrid solar collectors co-generating heat and electric power, as well as to solar collectors using
external power sources for normal operation and/or safety purposes. It does not cover electrical safety
aspects or other specific properties directly related to electric power generation.
This document is not applicable to those devices in which a thermal storage unit is an integral part to
such an extent that the collection process cannot be separated from the storage process for making the
collector thermal performance measurements.

Solarenergie - Thermische Sonnenkollektoren - Prüfverfahren (ISO 9806:2017)

Énergie solaire - Capteurs thermiques solaires - Méthodes d'essai (ISO 9806:2017)

L'ISO 9806:2017 spécifie les méthodes d'essai permettant d'évaluer la durabilité, la fiabilité, la sécurité et la performance thermique des capteurs solaires à circulation de fluide. Les méthodes d'essai sont applicables pour les essais en laboratoire et les essais in situ.
L'ISO 9806:2017 s'applique à tous les types de capteurs solaires à circulation de liquide, de capteurs solaires à air, de capteurs hybrides solaires produisant de l'énergie thermique et électrique ainsi que des capteurs solaires utilisant des sources d'alimentation externes pour leur fonctionnement normal et/ou à des fins de sécurité. Il ne traite pas des aspects de sécurité électrique ni d'autres propriétés spécifiques directement en rapport avec la production d'énergie électrique.
L'ISO 9806:2017 ne s'applique pas aux appareils dans lesquels un dispositif de stockage thermique fait partie intégrante dans la mesure où les opérations de captage et de stockage de l'énergie ne peuvent pas être séparées en vue d'effectuer des mesures de performance thermique du capteur.

Sončna energija - Sprejemniki sončne energije - Preskusne metode (ISO 9806:2017)

Ta dokument določa preskusne metode za ocenjevanje trajnosti, zanesljivosti, varnosti in toplotne učinkovitosti sprejemnikov sončne energije za ogrevanje tekočine. Preskusne metode se uporabljajo za laboratorijsko preskušanje in preskušanje na mestu uporabe.
Ta dokument se uporablja za vse vrste sprejemnikov sončne energije za ogrevanje tekočine, sprejemnikov sončne energije za ogrevanje zraka, hibridne sprejemnike sončne energije, ki proizvajajo toploto in električno energijo, ter sprejemnikov sončne energije, ki uporabljajo zunanje vire energije za normalno delovanje in/ali varnostne namene. Ne vključuje vidikov električne varnosti
ali drugih določenih lastnosti, ki so neposredno povezane s proizvodnjo električne energije.
Ta dokument se ne uporablja za naprave, pri katerih je enota za shranjevanje toplote sestavni del do te mere, da postopka sprejemanja ni mogoče ločiti od postopka shranjevanja za pripravo meritev toplotne učinkovitosti sprejemnika.
