Ceramic products are indispensable in daily life and have a wide range of applications. Besides meeting performance standards, products also have certain requirements for appearance. Therefore, quality inspection must comprehensively consider the interests of the company, society, and consumers.
As the birthplace of ceramics, China has seen rapid development of this traditional industry since joining the World Trade Organization, with production now ranking first in the world. However, there is still a gap in product quality compared to developed countries. Rigorous quality inspection is crucial to improving product quality.
Inspección de calidad refers to the process of testing one or more product properties using instruments and human senses, comparing the results with specified quality standards, and determining whether the product meets the standards.
Take Hanyu Ceramics Technology Co., Ltd. as an example. The company regularly participates in national ceramic product quality inspections each year. After rigorous testing by the Chaozhou Quality and Metrology Supervision and Inspection Institute in Guangdong Province, it received a qualified inspection report, ensuring the continued high quality of ceramic sinks.
How can you understand product quality from an inspection report?
A complete quality inspection report typically covers multiple key indicators. For example, Hanyu Ceramics recently underwent testing that included the following:
1. Consignor and Manufacturer: Guangdong Hanyu Ceramics Technology Co., Ltd.
2. Testing Agency: National Ceramics and Plumbing Products Quality Inspection and Testing Center
3. Testing Basis:
- GB/T 6952-2015 “Sanitary Ceramics”
- GB 6566-2010 “Limits of Radionuclides in Building Materials”
4. Testing Environment: Temperature 21-24°C, Relative Humidity 50%-70%
Main Inspection Items and Results:
- Appearance Quality (Glaze and External Defects, No Color Differences for the Same Product or Matching Products) – Compliant
- Allowable Deformation Range (Mounting Surface ≤ 3mm, Surface ≤ 6mm, Overall ≤ 8mm, Edge ≤ 4mm) – Compliant
- Water Absorption (Porcelain ≤ 0.5%) – Compliant
- Crack Resistance (No glaze cracks or body cracks after testing) – Compliant
- Load Capacity (Wall-mounted basin withstood 1.1 kN load, no structural failure or deformation upon testing) – in compliance.
Not only do such tests ensure the product’s durability and safe use, but also lay the critical basis for companies to achieve the respective certifications and access to the market. Products need to pass such tests before distribution in markets with mandatory certification.
How Can Consumers Evaluate Ceramic Basin Quality Inspection Themselves?
Even without a professional test report, there are a few simple ways of first estimating the quality of a ceramic basin when purchasing:
- Inspection of glaze: A good ceramic sink has a bright, glossy glaze with a pure color that resists stains easily and is easy to clean. Observe it from various positions in direct light. Good glaze should be free from color, pinholes, pinholes, or bubbles and should reflect light evenly and softly.
- Touch it: The surface should be level and even, without bumps or indentations. Some professionals also recommend that if there is a faint “rustling” sound when rubbing the back of the ceramic, it typically indicates high density and high-grade material.
- Comparison: If conditions permit, check side by side products of different brands to more readily detect differences in glaze color, shape, and craftsmanship.
