Overview
ASTM D7055-19: Standard Practice for Preparation (by Abrasive Blast Cleaning) of Hot-Rolled Carbon Steel Panels for Testing of Coatings establishes a systematic procedure for preparing hot-rolled carbon steel panels through abrasive blast cleaning. The primary objective is to ensure the panels have a uniform and reproducible surface, which is a critical prerequisite for valid laboratory testing of coatings performance. This standard is instrumental in enhancing the reliability and consistency of laboratory coating evaluations.
ASTM D7055-19 is developed by ASTM International and aligns with internationally recognized standardization principles. The practice clearly outlines methods for degreasing, specifying the required surface cleanliness, selecting abrasive type and profile, and verifying the end-condition of prepared panels.
Key Topics
- Abrasive Blast Cleaning Procedures
- Specifications for degreasing prior to abrasive blast (solvent or alkaline cleaning)
- Detailed instructions on abrasive blast cleaning and acceptable abrasive types
- Specification of surface cleanliness (using SSPC/NACE standards)
- Guidelines on selecting surface profile (fine, medium, coarse)
- Test Panel Requirements
- Material specifications (A36/A36M, A572/A572M, A1011/A1011M, or as agreed)
- Panel dimensions and preconditioning (removal of burrs, breaking sharp edges)
- Rust grade classification prior to cleaning (Grade A: intact mill scale; Grade B: rusted)
- Assessment and Documentation
- Methods for evaluating surface cleanliness and profile
- Use of photographic and instrumental methods for verification
- Comprehensive reporting of panel preparation details
- Preservation Post-Preparation
- Wrapping or storing methods to protect cleaned panels from corrosion prior to coating application
Applications
ASTM D7055-19 is widely used in laboratories and industrial settings where the performance of protective coatings must be tested reliably. Applying this standard ensures that:
- Laboratory Coating Testing: Panels used in cyclic corrosion, salt spray, and adhesion tests have uniform, controlled surface conditions, eliminating variability that can distort results.
- Coating Research and Development: Manufacturers and researchers can demonstrate coating effectiveness on comparably prepared substrates, supporting product claims and regulatory submissions.
- Quality Assurance in Metal Finishing: Companies involved in the production or evaluation of protective coatings use this standard for in-house verification and third-party testing compliance.
The practice is essential for sectors such as automotive, marine, construction, oil & gas, and heavy manufacturing, where coatings must withstand harsh environments.

3. Summary of Practice
3.1 This practice enables the user to specify the level of preparation of hot-rolled carbon steel test panels (prepared by dry
abrasive blast cleaning) for testing of coatings, including the steel composition, the degree of surface cleanliness, and the type of
abrasive.
4. Significance and Use
4.1 The procedures described in this practice are designed to provide hot-rolled, carbon steel panels with uniform and
reproducible abrasive blast cleaned surfaces for testing of coatings.
5. Test Panels
5.1 Prepare the test panels from unpainted hot-rolled steel plate or bar stock.
5.2 The panels shall be made to a size and thickness as agreed upon between the purchaser and seller.
5.3 The steel composition shall be either Specifications A36/A36M, A572/A572M, A1011/A1011M or as agreed upon between
the purchaser and seller.
5.4 The surface condition of the steel prior to surface preparation shall be specified and shall be one of two rust grades based
on SSPC-VIS 1: Grade A, intact mill scale; or Grade B, rusting mill scale. If SSPC-SP 6/NACE No. 3 is specified in 6.2, then the
surface condition shall be Grade B.
5.5 Remove any burr from saw-cut or sheared edges of the test panels.
5.6 Break sharp corners and/or edges using a grinding wheel.
6. Methods of Preparation
6.1 Degreasing—Prior to abrasive blast cleaning degrease the panels surfaces using one of the methods listed below from
SSPC-SP1.

appropriate solvent. If excessive oil or grease is present, power brush the surface vigorously and re-rinse or wipe.
6.1.2 Alkaline or Detergent Cleaning—Aqueous alkaline cleaners are available from a number of sources as proprietary
compounds or processes. Clean the panels with an alkaline solution or cleaner applied by spray or immersion. Brush or wipe in
accordance with the recommendations of the cleaner manufacturer. One or more steps of rinsing with water is required after this
cleaning procedure. To prevent rust formation, force dry the panel surfaces immediately after rinsing.

6.2.3 SSPC-SP 10/NACE No. 2—Near-White Metal Blast Cleaning.
6.2.4 Default Degree of Cleaning—If no degree of cleaning is specified, solvent clean the panels as described in 6.1.1, then
abrasive blast clean the panels to “White Metal Blast Cleaning” as described in 6.2.1.
6.3 Select the Surface Profile (anchor pattern) Depth—Select a surface profile range of fine, medium or coarse as defined below,
or specify an alternative range.
6.3.1 Fine: 1.0 to 2.5 mils (25-63 μm).
6.3.2 Medium: 1.5 to 3.5 mils (38-89 μm).
6.3.3 Coarse: 3.0 to 5.0 mils (75-125 μm).
6.3.4 Alternative Range—Alternative Range: The range between the minimum and maximum shall be at least 1.0 mil (25 μm).
6.3.5 Default Surface Profile Range—Default Surface Profile Range: If no surface profile range is specified, the range shall be
Medium.
6.4 Select the Abrasive Type—Select the abrasive type as defined below, or specify an alternative abrasive.
