Kovinske prevleke - Preskusne metode za galvansko nanašanje zlata in njegovih zlitin - 3. del: Elektrografsko ugotavljanje poroznosti (ISO 4524-3:2021)

Ta dokument določa:
– mere ter mehanske, hidravlične in akustične značilnosti, ki jim naj ustrezajo regulatorji pretoka za sanitarne armature (z regulacijo pretoka in brez nje);
– postopke za preskušanje teh značilnosti.
Ta dokument se uporablja za:
– regulatorje pretoka za sanitarne armature, namenjene za namestitev na armature, ki se uporabljajo s sanitarnimi napravami v straniščih, kopalnicah in kuhinjah (npr. enojne pipe, kombinirane pipe, mehanski mešalni ventili, termostatski mešalni ventili);
– regulatorje pretoka za sanitarne armature, ki se uporabljajo v naslednjih tlačnih in temperaturnih pogojih:
Opomba 1: Regulatorje pretoka za sanitarne armature je mogoče priključiti samo za tesnilom sanitarne armature.
Opomba 2: Zaradi jedrnatosti se v preostalem delu tega dokumenta namesto izraza regulatorji pretoka za sanitarne armature uporablja samo izraz regulatorji pretoka.
Opomba 3: Preskusi, opisani v tem dokumentu, so tipski preskusi (laboratorijski preskusi) in ne kontrolni preskusi kakovosti, opravljeni med proizvodnjo.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
