1. Scope* 使用范围

 

1.1 This test method covers the evaluation of the degree of rusting on painted steel surfaces. The visual examples which depict the percentage of rusting given in the written specifica-tions form part of the standard. In the event of a dispute, the written definition prevails. These visual examples were developed in cooperation with SSPC: The Society for Protective Coatings to further standardization of methods.

此测试办法针对涂漆钢铁表面锈蚀程度的评定(判定). 描述生锈比例的图示样品也是此标准的一部分. 若图示与书面定义有冲突, 则以书面定义为准. 这些图示经与SSPC合作完成: 保护性涂层协会使方法进一步标准化.

 

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

若存在与使用此标准相关的安全顾虑, 此标准不声称解决. 标准使用者有责任建立正确的安全和健康惯例, 并在使用前确定监管限制的实用性.

3. Significance and Use 重要性和用途

 

3.1 The amount of rusting beneath or through a paint film is a significant factor in determining whether a coating system should be repaired or replaced. This test method provides a standardized means for quantifying the amount and distribution of visible surface rust.

漆层生锈的多少是决定表层系统是否需修补或更换的重要因素. 此测试办法提供标准手段以判定可视生锈的多少及分布状况.

 

3.2 The degree of rusting is evaluated using a zero to ten scale based on the percentage of visible surface rust.

根据可视表面生锈的百分比, 从0-10级判定生锈程度.

 

This test method is under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications and is the direct responsibility of Subcommittee D01.46 on Industrial Protective Coatings.

此测试方法由ASTM(美国材料实验协会)的喷漆&相关涂层, 物质和使用D01委员会管辖, 由其下属的工业保护性涂层委员会D01.46直管.

 

This test method has been jointly approved by ASTM and SSPC: The Society for Protective Coatings.

此测试办法经ASTM和SSPC联合通过.

3.3 The distribution of the rust is classified as spot rust, general rust, pinpoint rust or hybrid rust.

生锈的分布类型有: SPOT RUST(点状生锈), GENERAL RUST(一般性生锈), PINPOINT RUST(针状生锈)或HYBRID RUST(混合生锈). (注: 此分类与后文图示对应)

 

4. Interferences 关联

 

4.1 The visual examples that are part of this test method and the associated rust-grade scale cover only rusting evidenced by visible surface rust. 图示是此标准方法的一部分, 相关的生锈等级只针对可视的表面生锈.

 

4.2 The use of the visual examples requires the following cautions: 使用图示时, 需注意如下:

 

4.2.1 Some finishes are stained by rust. This staining must not be confused with the actual rusting involved. 有些表层受锈蚀污染. 污染区域不得算作实际生锈.

 

4.2.2 Accumulated dirt or other material may make accurate determination of the degree of rusting difficult. 灰尘或其它物价质数的累积将使精确定级的难度增大.

 

4.2.3 Certain types of deposited dirt that contain iron or iron compounds may cause surface discoloration that should not be mistaken for corrosion. 某些沉垫的含铁或铁混合物的灰尘将导致表面变色, 这不能误认为生锈.

 

4.2.4 Failure may vary over a given area. Discretion must therefore be used when selecting a single rust grade or rust distribution that is to be representative of a large area or structure, or in subdividing a structure for evaluation. 面积不同, 失效可能也不同. 所以, 当选择单个生锈等级或分布作为大面积或结构的代表时, 必须准确判断, 或者细分结构再评估.

 

4.2.5 The color of the finish coating should be taken into account in evaluating surfaces as failures will be more apparent on a finish that shows color contrast with rust, such as used in these reference standards, than on a similar color, such as an iron oxide finish. 在评估表面情况时, 涂层的颜色应考虑进去. 颜色与锈蚀对比差别较大时, 失效更容易看出来, 而如果颜色与锈蚀接近时, 则没那么明显.

 

5. Procedure 步骤

 

5.1 Select an area to be evaluated. 选定需评估的区域.

 

5.2 Determine the type of rust distribution using definitions in Table 1 and visual examples in Fig. 1, Fig. 2, and Fig. 3. 根据Table 1(表格1)和视图Fig.1, Fig.2&Fig.3的定义判断生锈分布的类型.

 

5.3 Estimate percentage of surface area rusted using the visual examples in Fig. 1, Fig. 2, and Fig. 3 or SSPC-VIS 2, or both, by electronic scanning techniques or other method agreed upon by contracting parties. 参照视图Fig.1, Fig.2, Fig.3, 或SSPC-VIS 2, 或两者同时使用, 通过电子扫描技术或当事方同意的其它方法估算生锈的比例.

 

NOTE 1—The numerical rust grade scale is an exponential function of the area of rust. The rust grade versus area of rust is a straight line plot on semilogarithmic coordinate from rust grade 10 to rust grade 4. The slope of the curve was changed at 10 % of the area rusted to 100 % rusted to permit inclusion of complete rusting on the 0 to 10 rust scale. 注解1-数字等级是生锈面积的指数. 在生锈等级10级-4级之间, 生锈等级与生锈面积直线型的半对数关联. 当生锈面积在10%-100%之间时, 曲线的斜度将会改变, 以在0-10的生锈比例中包括完全生锈.

Summary of Changes section appears at the end of this standard. 修改概要见本标准末尾

 

TABLE 1 Scale and Description of Rust Ratings 生锈等级的比例和描述

 

Rust Distribution Types(生锈分布类型):

 

S: Spot Rusting—Spot rusting occurs when the bulk of the rusting is concentrated in a few localized areas of the painted surface. The visual examples depicting this type of rusting are labeled 9-S thru 1-S (See Fig. 1, Fig. 2, and Fig. 3). 点状-当生锈集中于某些区域时. 图示为9-S至1-S (见Fig.1, Fig.2, Fig.3)

 

G: General Rusting—General rusting occurs when various size rust spots are randomly distributed across the surface. The visual examples depicting this type of rusting are labeled 9-G thru 1-G. (See Fig. 1, Fig. 2, and Fig. 3). 一般性-当大小不一的锈点随意分布于表面时. 图示为9-G至1-G (见Fig.1, Fig.2, Fig.3)

 

P: Pinpoint Rusting—Pinpoint rusting occurs when the rust is distributed across the surface as very small individual specks of rust. The visual examples depicting this type of rusting are labeled 9-P through 1-P. (See Fig. 1, Fig. 2, and Fig. 3). 针状- 当生锈呈很小单个斑点分布于表面时. 图示为9-P至1-P (见Fig.1, Fig.2, Fig.3)

 

H: Hybrid Rusting—An actual rusting surface may be a hybrid of the types of rust distribution depicted in the visual examples. In this case, report the total percent of rust to classify the surface. 9-H through 1-H. 混合性-实际生锈表面可能是以上多种类型混合在一起. 此时, 根据总的生锈面积判定等级. 9-H至1-H.

 

5.4 Use percentage of surface area rusted to identify rust grade (see Table 1). Assign rust rating using rust grade of 0-10 followed by the type of rust distribution identified by S for spot, G for general, P for pinpoint or H for Hybrid. 根据生锈表面判定等级(见Table 1). 通过S(点状), G(一般性), P(针状)和H(混合性)区别具体分布.

 

5.5 The visual examples are not required for use of the rust-grade scale since the scale is based upon the percent of the area rusted and any method of assessing area rust may be used to determine the rust grade. 由于生锈比例以生锈面积为基础, 使用生锈等级表时不要求图标; 而且, 可能会用到各种判定生锈等级的方法.

6. Report 报告

6.1 Identify sample or area evaluated. 描述/说明被评估的样品或区域.

6.2 Report rust grade using rating of 0-10. 报告生锈等级(1-10)

6.3 Report rust distribution using S for Spot, G for General, P for Pinpoint and H for Hybrid. 报告生锈类型.

7. Precision and Bias 精确度和边缘性

7.1 No precision or bias statement can be made for this test method. 没相关声明

8. Keywords 主题词

8.1 corrosion; rusting 腐蚀; 生锈
