Overview

SIST ISO 7622-2:1999 outlines a standardized method for determining the longitudinal tensile strength of steel cord conveyor belts using a specific traction test. This standard, developed by the International Organization for Standardization and adopted by SIST, ensures reliable and consistent measurement of tensile strength exclusively for conveyor belts with a steel carcass. The procedure provides vital data for quality assurance, particularly when certificates of compliance are unavailable or in dispute cases.

Key Topics

Longitudinal Traction Test: Defines a destructive testing method targeting the steel cords that make up the conveyor belt carcass, providing a direct measurement of tensile strength in the direction of belt travel.

Test Specimen Preparation: Specifies detailed requirements for preparing test specimens, including dimensions, placement of cords, and types A and B preparations to ensure consistent testing conditions.

Testing Apparatus: Describes suitable dynamometric tensile testing machines, specifying:

Capacity to accommodate various specimen strengths
Adjustable and constant jaw separation rates
Secure grips to eliminate slippage

Testing Procedure: Outlines conditions for test execution, including the number of specimens, environmental settings (temperature and humidity), and measurement accuracy.

Reporting Results: Requires clear documentation of testing conditions, mean breaking forces, and calculation of longitudinal tensile strength according to standardized formulas.

Applications

Steel cord conveyor belts are integral in industries such as mining, bulk material handling, and manufacturing due to their strength and longevity. This standard finds practical value in:

Quality Control: Manufacturers can verify that steel cord conveyor belts conform to specified tensile strength requirements, ensuring product reliability.

Compliance Verification: Used by third-party laboratories or buyers in case of disputes over product strength or in the absence of compliance certificates.

Safety Assurance: Accurate measurement of tensile strength helps prevent equipment failure and operational hazards in conveyor systems.

Comparative Benchmarking: Provides a consistent baseline for comparing belt tensile strength across suppliers and production batches.

Related Standards

For comprehensive quality assurance and compatibility with SIST ISO 7622-2:1999, consider the following related standards:

ISO 7622-1: Steel cord conveyor belts - Part 1 covers the measurement of elastic elongation.

ISO 471: Specifies standard temperatures, humidities, and conditioning times for rubber testing, ensuring consistent test environments.

ISO/TC 41 Standards: Additional standardized testing and technical requirements for belts and pulleys.

Conclusion

SIST ISO 7622-2:1999 is essential for manufacturers, quality control engineers, and purchasers involved with steel cord conveyor belts, providing a standardized method to quantify longitudinal tensile strength. Adherence to this standard supports product reliability, safety, and international trade compliance, making it highly relevant for conveyor belt testing in diverse industrial applications. Using recognized standards also facilitates transparent reporting and trust in the supply chain, reinforcing the value of ISO-compliant quality assessments.
