Overview
SIST EN ISO 10764:2016 - Footwear - Test methods for slide fasteners - Lateral strength sets out a standardized method for assessing the lateral strength of closed slide fasteners (zippers) used in footwear. As published by CEN and identical to ISO 10764:2016, this standard is applicable to all types of slide fasteners fitted in footwear, enabling manufacturers, quality controllers, and testing laboratories to evaluate the durability and reliability of shoe fasteners under lateral force. Consistent testing practices support the production of high-quality, long-lasting footwear products, ensuring consumer satisfaction and safety.
Key Topics
-
Test Methodology: SIST EN ISO 10764:2016 details the process for measuring the lateral strength of slide fasteners when closed and subjected to a specified force. This includes conditioning, equipment requirements (such as tensile testing machines), specimen preparation, and reporting protocols.
-
Applicability: The method can be used on all types of slide fasteners, including metal, plastic, and coil zippers commonly found in various types of footwear.
-
Repeatable Results: By providing clear instructions, the standard ensures repeatability and comparability of results across different laboratories and among footwear producers.
-
Quality Assurance: Following SIST EN ISO 10764:2016 contributes to robust quality management in the footwear industry by identifying weak points in fastener attachment or materials.
-
International Alignment: As a harmonized European and ISO standard, it supports global trade and compliance, helping manufacturers meet both European and international regulatory expectations.
Applications
SIST EN ISO 10764:2016 is vital for a range of stakeholders in the footwear industry:
-
Footwear Manufacturers: Facilitates in-house quality control of zippers, enabling detection of potential issues before products reach the market. Supports product development and benchmarking of fastener strength.
-
Testing Laboratories: Provides a reference method for independent assessment of footwear fasteners’ lateral strength, useful in certification and compliance testing.
-
Suppliers and Component Makers: Assists suppliers of zippers or slide fasteners in demonstrating the compliance and durability of their products to footwear brands.
-
Retailers and Buyers: Ensures that the footwear sourced meets recognized durability expectations, reducing returns and increasing consumer trust.
-
Regulatory Authorities: Aids in benchmarking products against regional, national, and international requirements, supporting market surveillance.
The standard is especially valuable in the production of sports, work, and outdoor shoes where reliability of fasteners is mission-critical. Ensuring zippers can withstand lateral forces during normal use protects both the integrity of the footwear and the safety of the wearer.
Related Standards
To carry out the testing procedures described in SIST EN ISO 10764:2016, reference is made to several supporting standards:
- ISO 7500-1: Metallic materials - Verification of static uniaxial testing machines - ensures test equipment calibration.
- ISO 18454: Footwear - Standard atmospheres for conditioning and testing of footwear and components of footwear.
- ISO 19952: Footwear - Vocabulary - defines key terms used throughout testing and documentation.
Other relevant standards within footwear testing and fastener evaluation may include those covering durability, attachment strength, and overall product safety.
By following SIST EN ISO 10764:2016, organizations demonstrate a commitment to quality and consistency in footwear fastener testing, supporting product reliability and compliance across markets.
