Paints and varnishes - Electrochemical impedance spectroscopy (EIS) on coated and uncoated metallic specimens - Part 2: Collection of data (ISO 16773-2:2016)

ISO 16773-2:2016 gives guidelines for optimizing the collection of EIS data with focus on high-impedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 Ω⋅cm2. This does not preclude measurements on systems with lower impedance. For uncoated samples extra information can be found in ISO/TR 16208.
ISO 16773-2:2016 deals with the following:
-      instrumental set-up: requirements and pit-falls;
-      data validation: checking the measurement range and the accuracy of the data;
-      performing an EIS measurement: specimen considerations and instrumental parameters;
-      the experimental results: different methods of presenting EIS data.
These guidelines are intended to ensure the acquisition of EIS data that can be used to study the performance of the specimen. This part of ISO 16773 does not give guidelines for the interpretation of the data.

Elektrochemische Impedanzspektroskopie (EIS) an beschichteten und unbeschichteten Proben - Teil 2: Datenerfassung (ISO 16773-2:2016)

Dieser Teil von ISO 16773 enthält einen Leitfaden zum Optimieren der Erfassung von EIS-Daten bei Systemen mit hoher Impedanz. Hohe Impedanz im Zusammenhang mit intakten Beschichtungen bezieht sich auf Systeme, deren Impedanz größer ist als 109 Ω ⋅ cm2. Dies schließt die Messung von Systemen mit niedrigerer Impedanz nicht aus. Zusätzliche Ausführungen über unbeschichtete Proben sind im ISO/TR 16208 enthalten.
Dieser Teil von ISO 16773 behandelt Folgendes:
   Aufbau der Geräte, Anforderungen und „Fallstricke“;
   Gültigkeit, Überprüfung des Messbereiches und Genauigkeit der Daten;
   Durchführung einer EIS-Messung, Überlegungen zu den Proben und Geräteparameter;
   experimentelle Ergebnisse, verschiedene Darstellungsverfahren von EIS-Daten.
Dieser Leitfaden dient dazu, EIS-Daten zu erhalten, die zum Untersuchen Leistungsverhaltens der Probe ver¬wendet werden können. Dieser Teil von ISO 16773 gibt keine Hinweise zur Interpretation der Daten.

Spectroscopie d'impédance électrochimique (SIE) sur des éprouvettes métalliques revêtues et non revêtues - Partie 2: Recueil des données (ISO 16773-2:2016)

ISO 16773-2:106 fournit des lignes directrices pour l'optimisation du recueil des données de SIE en se focalisant en particulier sur les systèmes de haute impédance. Dans le contexte des revêtements intacts, «haute impédance» se réfère à des systèmes ayant une impédance supérieure à 109 Ω⋅cm2. Cela n'empêche pas le mesurage de systèmes d'impédance inférieure. En ce qui concerne les éprouvettes non revêtues, l'ISO/TR 16208 peut être consulté pour obtenir des informations complémentaires.
ISO 16773-2: 2016 traite:
-      du montage instrumental: exigences et problèmes;
-      de la validation des données: vérification de la plage de mesure et de la précision des données;
-      de l'exécution d'un mesurage de SIE: dispositions relatives à l'éprouvette et paramètres instrumentaux;
-      des résultats expérimentaux: les différentes méthodes de présentation des données de SIE.
Ces lignes directrices visent à garantir l'acquisition de données de SIE utilisables pour étudier les performances de l'éprouvette. La présente partie de l'ISO 16773 ne donne aucune ligne directrice concernant l'interprétation des données.

Barve in laki - Elektrokemijska impedančna spektroskopija (EIS) premazanih in nepremazanih kovinskih vzorcev - 2. del: Zbiranje podatkov (ISO 16773-2:2016)

Ta del standarda ISO 16773 podaja navodila za optimizacijo zbirke podatkov elektrokemijske impedančne spektroskopije s poudarkom na visokoimpedančnih sistemih. V okviru nepoškodovanih premazov se visoka impedanca nanaša na sisteme z
impedanco, višjo od 109 Ω⋅cm2. To ne izključuje meritev v sistemih z nižjo
impedanco. Dodatne informacije o nepremazanih vzorcih so podane v standardu ISO/TR 16208.
Ta del standarda ISO 16773 obravnava naslednje:
– priprava instrumentov: zahteve in nevarnosti;
– potrjevanje podatkov: preverjanje merilnega obsega in točnosti podatkov;
– izvajanje merjenja z elektrokemijsko impedančno spektroskopijo: upoštevanje vzorcev in parametrov instrumentov;
– rezultati preskusa: različne metode predstavitve podatkov elektrokemijske impedančne spektroskopije.
Ta navodila so namenjena za zagotavljanje pridobivanja podatkov elektrokemijske impedančne spektroskopije, ki se lahko uporabijo za preučevanje zmogljivosti vzorca. Ta del standarda ISO 16773 ne podaja navodil za razlago podatkov.
