Yes. REBO complies with global standards for acid proof bricks. REBO products meet the key requirements of ISO 10080. These standards cover acid resistance, water absorption, and mechanical strength. REBO also holds ISO 9001 and ISO 14001 certifications. SGS and TÜV independently verify its performance data. This allows REBO to serve chemical, metallurgical, and environmental projects worldwide.
Global Standards for Acid Resistant Bricks
Standard codes like ISO, ASTM, or EN may set the benchmarks for acid resistant bricks and tiles worldwide, but they all converge on one critical metric: zero-compromise chemical resistance. REBO products are rigorously engineered and certified to ISO standards consistently outperforming threshold parameters to deliver ultimate durability in the harshest corrosive environments.
| Standard System | Standard No. | Core Role | Scope | Key Content |
|---|---|---|---|---|
| ISO Standards | ISO 10080 | Product Classification Framework | Dense, Shaped Acid Resistant Products | 3 groups by sulfuric acid resistance (mass loss ≤2%, 2–4%, 4–7%); 2 sub-groups by apparent porosity (≤15%, >15%). Lower numbers=better acid resistance and higher density. |
| ISO 10545 Series | General Test Methods | All Ceramic Tiles | Defines how to test. Part 13 covers chemical resistance. Does not classify product grades. | |
| European Standards | EN 14411 | Product Definition & Classification | Extruded Or Dry-Pressed Ceramic Tiles | Classified by forming method: A (extruded), B (dry-pressed); grouped by water absorption. Group BIa requires ≤0.5% absorption, best for acid resistance. |
| EN ISO 10545-13 | Chemical Resistance Testing | All Ceramic Tiles | European adoption of ISO test method. Measures resistance to acids, alkalis, and salts. | |
| US Standards | ASTM C279 | Acid Resistant Brick Performance Spec | Acid Resistant Masonry In Chemical Environments | Three types: I, II, III. Type III requires lowest water absorption <1% and lowest acid solubility <8%. |
| ASTM C410 | Industrial Floor Brick Performance Spec | Industrial Flooring Bricks | Four types: T, H, M, L. T=thermal shock resistance; H=chemical resistance; M=low absorption; L=lowest absorption+high chemical resistance. | |
| Third-Party Verification | SGS/TÜV | Independent Compliance Verification | Does Not Set Standards, Only Verifies Compliance | Tests products per ISO, EN, ASTM standards and issues reports. Proves whether products truly meet standards. Key evidence for project tenders and CE certification. |
Critical Parameters of Acid Proof Bricks
| Parameter | Standard Requirement | REBO Test Data | Compliance/Performance | Why It Matters |
|---|---|---|---|---|
| Water Absorption | ≤ 0.5% (EN 14411 Group BIa) | ≤ 0.2% | ✓ Exceeds Standard | Minimizes Acid Penetration And Prevents Sub-Layer Corrosion. |
| Acid Resistance | High Class (ISO 10080) | ≥ 99.8% | ✓ Fully Compliant | Maximize Equipment Service Life In Harsh Chemical Environments. |
| Flexural Strength | > 35 N/mm² (EN 14411) | ≥ 120 MPa (~120 N/mm²) | ✓ Far Exceeds Standard (3x+ Strength) | Ensures High Load-Bearing Capacity Under Heavy Industrial Traffic. |
| Dimensional Tolerance | Compliant (ASTM C410) | ± 0.5 mm | ✓ High Precision | Ensures Tight Masonry Joint Alignment And Superior Sealing Quality. |
| Quality Certifications | Third-party Verified | ISO 9001/14001, SGS, TÜV | ✓ Fully Documented | Guarantees Batch-To-Batch Consistency And International Compliance. |
