ISO (Organizația Internațională pentru Standardizare) este o alianță globală a organismelor naționale de standardizare (organismele membre ISO). Elaborarea standardelor internaționale se realizează de obicei prin intermediul comitetelor tehnice ISO. Fiecare instituție membră interesată de un subiect pe care a fost înființat un comitet tehnic are dreptul de a fi reprezentată în comitet. În această activitate sunt implicate și organizații internaționale guvernamentale și neguvernamentale care colaborează cu organizațiile de standardizare. ISO lucrează îndeaproape cu Comisia Electrotehnică Internațională (IEC) în toate problemele de standardizare electrică.

International standards are drafted according to the rules given in Part 3 din Directiva ISO/IEC.

Draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. As members of the international standard release need at least 75% of the agency for approval.

Please note that some of the elements of this standard may be has been the subject of patent rights. ISO nu este responsabil pentru identificarea vreunuia sau a tuturor acestor drepturi de brevet.

International standard ISO3892 was developed by Technical Committee ISO/TC 107, Metallic and other inorganic Coatings, Subcomisia SC 2, Coordination of inspection methods and test methods.

Second edition cancel and replace the first edition (ISO 3892:1980), the revised version has been technology.

Warning – The materials, operations and equipment listed in this standard may be dangerous if appropriate precautions are not followed. This international standard is not intended to address all safety issues associated with its use. It is the user’s responsibility to establish appropriate safety and health practices and determine the applicability of international standards before use of regulatory restrictions.

ISO 3892-2000 “Filme de transformare pe materiale metalice – Măsurarea masei stratului de film pe unitatea de suprafață – metoda gravimetrică”

1 Domeniul de aplicare
This standard specifies the gravimetric method for determining conversion coating per unit area on metallic materials.

Method applicable to the

– phosphate coating on steel;

– Phosphate coating on zinc and cadmium;

– phosphate coating on aluminium and its alloys;

– Chromate coating on zinc and cadmium;

– the chromate coating on aluminium and its alloys.

ISO 3892-2000 “Filme de transformare pe materiale metalice – Măsurarea masei stratului de film pe unitatea de suprafață – metoda gravimetrică”

The method is only applicable to conversion coatings that do not contain any complementary coatings such as oil, water or solvent-based polymers or waxes.

Whether exist in these methods are not indicating measurement area bare spots or thickness is lower than the specified minimum value. în plus, single values obtained from each measurement area is the average thickness of the region. Will not further mathematical analysis on the single value, de exemplu, for the purpose of statistical control.
