Annexes A and B of this standard are for reference only.

소개하다
The rating method described in this standard recognizes that decorative and protective metallic and inorganic coatings on metal substrates may be anodic or cathodic. When rating the corrosion effects of these coatings, two assessments should be made:

— The ability of the coating to protect the substrate from corrosion and thus prevent degradation of the base material;

The ability of the coating to maintain its integrity and thus maintain a satisfactory appearance.

Although these functions overlap, they can be evaluated separately in terms of:

— Level of protection (Rp) related to corrosion of base metals;

— Appearance rating (라) in relation to coating deterioration.

The Protection class (Rp) assigns a number representing the ability of the coating to protect the base material from corrosion.

The appearance rating (라) assigns a series of letters and numbers to the overall appearance of the specimen, which includes all deterioration caused by the corrosion test or the environment.

메모 1 In evaluating inspection results, attention should be paid to exposing defects on the front panel or articles of the test and due consideration should be given. Intentional defects may also be introduced as part of testing procedures.

If the rating system is applied, the coating system must be known and reported. 가능하다면, it is especially important to know whether the coating is an anode or a cathode for the base material.

메모 2 일부 경우에, the determination of anodic and cathodic corrosion mechanisms may be very difficult (zinc chromate on steel or multilayer coatings). For the purposes of the present document, it is not necessary to understand these mechanisms.

1 범위
This standard provides a method for assessing the condition of decorative and protective metallic and inorganic coated panels or articles that have been exposed to corrosive environments for testing or other purposes.

It is suitable for test panels or components that are exposed to natural atmospheres, under moving or static conditions, or undergoing accelerated testing.

메모 1 Examples of such tests are given in the bibliography.

This standard recognizes that levels of protection can be objectively assessed in accordance with Article 6. 하지만, the assessment of appearance depends on a number of subjective factors (보다 6.2).

메모 2 The edges of the test panel or assembly may be protected, for example with tape or wax (paraffin), if this is an agreed part of the test and documented in the test report. If the sample is cut from a larger fragment and has exposed uncoated edges, the importance of this is overstated.

2 용어 및 정의
2.1 Protection Level Rp

The rating (표 참조 1) is assigned to the ability of the coating to protect the base material from corrosion

2.2 Protection Defects

Used to assess defects of the protection level, including shrinkage corrosion, pinhole corrosion, corrosion stains caused by substrate corrosion, blisters, and other defects involving base metal corrosion

메모 1: Blisters on aluminum and zinc alloy die castings usually indicate base metal corrosion, but may require the inspector’s judgment to determine whether bubbling occurs at the substrate coating interface.

2.3 Appearance Rating

Specifies the rating number and symbol used to describe the overall appearance of the sample (표 참조 2), including all defects resulting from exposure

2.4 Appearance Defects

Defects that damage the appearance of the sample (표 참조 2)

2.5 Performance Rating

A combination of the protection grade number (R p) followed by the slash mark followed by the Appearance grade number (라), 즉. R p/RA

2.6 Coating system

A particular series of sediments, including the thickness and type of layers in multilayered sediments and the treatment that has been applied to base metals

2.7 Important Surfaces

The part of the surface that is unutterably important to the appearance or serviceability of the article, and the part that will be covered or covered by the coating (see clause 5)
