The table below provides a clear breakdown of the dust particle size classes as defined by the standard. iso 85023 dust level chart pdf updated

ISO 8502-3 specifies a simple, field-friendly method using (commonly a transparent Scotch tape of defined tackiness) to lift dust from a prepared steel surface. The tape is then applied to a contrasting background (typically a white or black card), and the extracted dust is compared against a standardized reference scale.

Inspectors must also classify the physical size of the dust particles using an illuminated hand lens with 10x magnification. Description Particle Size Dimension Particles not visible Under 50 µm in diameter Class 1 Small particles Visible only under 10x magnification (50 µm to 100 µm) Class 2 Medium particles Note: Any overall discoloration of the tape (such

The size class defines the physical dimensions of the dust particles captured on the tape:

: Essential to protect the testing area from body oils and sweat. Execution Process ISO 8502-3 specifies a simple, field-friendly method using

Use clean, washed, and properly screened abrasives. Low-quality recyclables often break down into excessive fine dust.

The quantity rating evaluates the density of the dust particles trapped on the tape. The standard utilizes a visual comparative chart ranging from 0 to 5:

The International Organization for Standardization (ISO) has been a driving force in establishing standards for various industries worldwide. One such standard is ISO 8502, which deals with the preparation of steel surfaces for painting and other coatings. Specifically, ISO 8502-3 provides guidelines for assessing the dust level on steel surfaces before coating application. This essay will discuss the updated ISO 8502-3 dust level chart PDF and its significance in ensuring the quality of coating applications.
