GB T 24218-2 Upholstery fabrics Determination of tear strength
The determination of tear strength in upholstery fabrics is a critical parameter that ensures the durability and longevity of home textiles. This service aligns with the stringent requirements outlined in GB/T 24218-2, which specifies a method for determining the tear resistance of upholstery fabrics.
Upholstery fabrics are subjected to various stresses during use, including stretching, pulling, and tearing. Understanding how these fabrics withstand such forces is essential for manufacturers seeking to produce high-quality products. The test procedure detailed in GB/T 24218-2 involves a specific specimen preparation process followed by the application of defined tensile stress until failure.
The tear strength testing method outlined in this standard provides a standardized approach to measure the resistance of upholstery fabrics to tearing under specified conditions. This ensures that all tests conducted adhere to consistent methodologies, thereby facilitating comparability and repeatability across different laboratories and manufacturers.
In practice, this service involves several key steps:
- Specimen preparation according to the specifications in GB/T 24218-2.
- Clamping of prepared specimens into a tensile testing machine.
- Application of controlled stress until failure, recording the force at which this occurs.
The data obtained from these tests is crucial for quality managers and compliance officers to ensure that their products meet regulatory requirements. For R&D engineers, this service provides insights into material properties that can be used to improve product design. Procurement teams benefit by having reliable tear strength data when selecting suppliers.
GB/T 24218-2 is widely recognized in China and internationally for its accuracy and reliability. This standard ensures that the testing process is consistent, reproducible, and adheres to the highest quality standards. The results generated from this test can be used not only within the Chinese market but also in international markets where compliance with local standards is necessary.

| GB/T 24218-2 | Determination of tear strength of upholstery fabrics |
The table above summarizes the key standard that governs this service. Adherence to these standards ensures consistent and reliable results, which is crucial for maintaining product quality and compliance.
Applied Standards
In addition to GB/T 24218-2, there are other international standards that also address the determination of tear strength in fabrics. These include ISO 37:2006 and ASTM D5966-15, both of which provide alternative methods for assessing fabric tear resistance.
| Standard Code | Title |
|---|---|
| ISO 37:2006 | Determination of tear strength in fabrics - Method A (Zwicker method) |
| ASTM D5966-15 | Tear testing of fabrics - Constant rate of extension machine method |
The use of multiple standards allows for flexibility and adaptability in determining tear strength, ensuring that the chosen method best suits the specific requirements of the product being tested.
International Acceptance and Recognition
GB/T 24218-2 is widely recognized within China for its role in quality assurance, particularly for home textile products. However, as more global brands enter the Chinese market or expand their operations there, compliance with international standards such as ISO and ASTM becomes increasingly important.
The International Organization for Standardization (ISO) and ASTM International have developed alternative methods that are accepted globally. These include:
- ISO 37:2006
- ASTM D5966-15
While GB/T 24218-2 is primarily a Chinese standard, its principles and methodologies are consistent with internationally recognized practices. This ensures that any testing conducted using this method can be easily compared to results from other laboratories around the world.
The acceptance of these standards in international markets underscores their importance for manufacturers seeking to ensure product quality across diverse geographical areas. Compliance with such standards not only enhances reputation but also facilitates smoother trade processes and greater market access.
Environmental and Sustainability Contributions
The determination of tear strength through GB/T 24218-2 not only benefits product quality but also contributes positively to environmental sustainability. By ensuring that upholstery fabrics are robust enough to last longer, this test indirectly supports efforts towards waste reduction and resource conservation.
- Extended product lifespan reduces the frequency of replacement and disposal.
- Encourages the use of sustainable materials in fabric production.
- Promotes recycling by enhancing material quality.
