Isang Paunang Salita
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang alyansa ng mga pambansang pamantayan katawan (Mga katawan ng miyembro ng ISO). Ang pagbuo ng mga internasyonal na pamantayan ay karaniwang isinasagawa sa pamamagitan ng ISO teknikal na komite. Ang bawat institusyon ng miyembro na interesado sa isang paksa kung saan ang isang teknikal na komite ay itinatag ay may karapatang kumatawan sa komite. Ang pamahalaan at mga di pampamahalaang internasyonal na organisasyon na nakikipag ugnayan sa mga organisasyon ng standardization ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.

International standards are drafted according to the rules given in Part 3 ng Direktiba ng 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 ay hindi responsable para sa pagtukoy ng anumang o lahat ng naturang mga karapatan sa patent.

International standard ISO3892 was developed by Technical Committee ISO/TC 107, Metallic and other inorganic Coatings, Subcommittee 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.

Babala – 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 “Transformation films sa metallic materyales – Pagsukat ng masa ng film layer per unit area – paraan ng gravimetric”

1 Saklaw
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 “Transformation films sa metallic materyales – Pagsukat ng masa ng film layer per unit area – paraan ng gravimetric”

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. Bukod pa rito, single values obtained from each measurement area is the average thickness of the region. Will not further mathematical analysis on the single value, halimbawa na lang, for the purpose of statistical control.
