What Is The Inspection Standards for Finished Ceramic Toilets?

Ceramic toilets play an essential role in modern sanitation systems, providing efficient waste management and hygiene assurance. To ensure the quality and reliability of these necessary fixtures, strict inspection standards must be followed. The following is a detailed discussion of the inspection standards for ceramic toilets, covering aspects such as appearance, dimensions, crack resistance, structure, drainage, load resistance, compatibility with flushing devices, sealing requirements, and packaging.

1. Appearance Requirements

① Color Variance: The ceramic toilet should exhibit a uniform color without noticeable color differences. Color variance can be evaluated through visual inspection under standard lighting conditions.

② Surface Oil Layer and Smoothness: The surface should be free from oil layers or irregularities. Inspections are conducted through visual and tactile assessment.

③ Pinholes, Black Spots, and Cracks: The toilet surface should be free from pinholes, black spots, and cracks. These defects are identified through visual inspection.

④ Billet Cracks and Glaze Cracks: Both the ceramic body and the glaze need to be checked for cracks, using visual inspection and careful observation to discover these flaws.

⑤ Dents, Paint, Stains, Pits, Bumps, and Glaze Bubbles: These defects must be recorded through visual inspection to document any abnormalities on the toilet surface.

2. Dimensions

① Height: Measure the height of the toilet using calibrated measuring tools.

② Aperture: Use appropriate tools to measure the aperture of the toilet.

③ Sewage Outlet Installation Distance: Accurately measure the distance from the center of the sewage outlet to the reference point.

④ Installation Surface Flatness: Check the flatness of the installation surface using visual inspection and measuring tools.

⑤ Verticality of Installation Holes: Measure the verticality of the installation holes with a level or similar instrument.

3. Crack Resistance

Assess the crack resistance of the toilet by applying impact or pressure tests. After testing, check for any visible cracks or damage to the toilet.

4. Structure

① Ligand Thickness and Glaze Layer Thickness: The thickness of the ligand and glaze layers is measured using appropriate tools.

② Water Seal Depth and Area: Measure the depth and area of the water seal to ensure effective sealing and prevent odor leakage.

③ Adaptability: Evaluate the toilet's adaptability to various installation conditions and sanitary fittings by checking the compatibility of different components.

5. Drainage

① Red Ink Test: Inspect the effectiveness of the water flow during flushing to ensure the toilet can adequately disperse the ink.

② Artificial Stool Test and Ball Test: Assess the toilet's ability to efficiently discharge solid waste, ensuring it can move the sphere correctly and is free from blockages.

③ Water Consumption and Sewage Replacement: Measure the water consumption and the amount of sewage replaced during flushing to evaluate the efficiency of water use and waste disposal.

6. Load Resistance

Evaluate the load capacity of the toilet by applying specific weights or pressure tests. The toilet should withstand loading without structural deformation or damage.

7. Compatibility of Flushing Devices

① Technical Requirements of Flushing Devices: Assess the compatibility of the toilet with different types of flushing devices through functional and fitting tests.

② Technical Requirements for Safe Water Level: Determine the safe water level of the toilet to prevent overflow and ensure optimal water use, requiring accurate measurements and adjustments.

8.Sealing Requirements for Links

Sealing requirements involve the connections between the toilet and other sanitary fittings (such as supply and drainage pipes). Proper sealing is crucial to prevent leaks and ensure efficient operation.

9. Packaging

The packaging of completed ceramic toilets must be inspected to ensure adequate protection during transport and storage. Packaging should be sturdy, clearly marked, and provide sufficient cushioning to prevent breakage or damage.
