panimula
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang pederasyon ng mga pambansang pamantayan ng 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 grupo ng miyembro na interesado sa isang paksa kung saan ang isang teknikal na komite ay itinatag ay may karapatang kumatawan sa Komite. Mga internasyonal na organisasyon, ang mga pamahalaan at mga non government organization na nakikipag ugnayan sa ISO ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.

Ang draft international standard na pinagtibay ng Technical Committee ay ipapakalat sa mga miyembro ng mga katawan para sa pagboto. Publication as an international standard requires approval by a vote of at least 75% of the member bodies.

The international standard ISO 8502-5 was developed by Technical Committee ISO/TC 35, Mga Pintura at Varnishes, Sub-Committee SC 12, Preparation of steel substrates prior to the application of paints and related products.

ISO 8502 binubuo ng mga sumusunod na bahagi, under the general heading Preparation of steel substrates prior to painting and associated products – Surface cleanliness assessment tests:

ISO 8502-5-1998 Preparation of steel substrates before painting and related products – Test for assessment of surface cleanliness – Bahagi 5: Measurement of chlorides on steel surfaces ready for painting (ion tube method)

– Bahagi 1: Field tests of soluble iron corrosion products [Technical report]

– Bahagi 2: Laboratory determination of chlorides on clean surfaces

– Bahagi 3: Assessment of dust on the surface of steel prepared for coating (pressure sensitive tape method)

– Bahagi 4: Guidelines for estimating condensation probability before painting

– Bahagi 5: Determination of chlorides on coated steel surfaces (ion tube method)

– Bahagi 6: Extraction of soluble contaminants for analysis – Bresle method

– Bahagi 8: Field method for determination of moisture refraction

– Bahagi 9: Field method for determination of conductance of water-soluble salts.

– Bahagi 10: Field method for titration of chlorides

Other parts are being planned.

ISO 8502-5-1998 Preparation of steel substrates before painting and related products – Test for assessment of surface cleanliness – Bahagi 5: Measurement of chlorides on steel surfaces ready for painting (ion tube method)

1 Saklaw ng Aplikasyon
Ang bahaging ito ng ISO 8502 describes field tests using special detection tubes to measure chloride ions.

With suitable surface sampling techniques, the test applies to steel surfaces before and after cleaning, as well as painted surfaces between coats.

ISO 8502-2, Preparation of steel substrates before painting and related products – Mga pagsubok para sa pagtatasa ng kalinisan ng ibabaw – Bahagi 2: Laboratory determination of chlorides on clean surfaces – Laboratory method for determination of chlorides on surfaces is described.
