ISO 4628-3 Rust Visual Rating Laboratory Testing Service: A Comprehensive Guide
ISO 4628-3 is a widely recognized international standard that governs the visual rating of rust on steel surfaces. This standard is part of the ISO 4628 series, which provides guidelines for assessing the corrosion resistance and durability of steel products. The standard is developed by the International Organization for Standardization (ISO) and is used globally by industries such as construction, manufacturing, and infrastructure development.
The legal and regulatory framework surrounding ISO 4628-3 testing is governed by various national and international standards. In Europe, the European Committee for Standardization (CEN) has adopted ISO 4628-3 as a harmonized standard (EN ISO 4628-3). Similarly, in the United States, the American Society for Testing and Materials (ASTM) has developed an equivalent standard (ASTM A787).
Internationally, the International Electrotechnical Commission (IEC) has recognized ISO 4628-3 as a global standard for rust visual rating. The standard is also referenced in various national standards, including those from Turkey (TSE), China (GB), and India (IS).
The standard development organizations involved in developing and maintaining ISO 4628-3 include:
Standards evolve over time as new technologies, materials, and testing methods emerge. ISO 4628-3 has undergone several revisions since its initial publication in 1979. The latest version, published in 2016, incorporates updated testing methods, equipment, and calibration procedures.

ISO 4628-3 testing involves a series of standardized procedures and protocols. The following steps outline the test conditions and methodology:
1. Sampling: Selecting representative steel samples for testing
2. Preparation: Cleaning, drying, and protecting the sample surfaces
3. Exposure: Exposing the samples to corrosive environments (e.g., humidity chambers)
4. Visual assessment: Rating the rust damage using standardized criteria
5. Calibration: Calibrating the testing equipment according to international standards
The test is conducted in a controlled environment, with precise temperature and humidity conditions.
