ISO 13202:2003

Overview

ISO 13202:2003 provides guidelines for measuring the velocity and time parameters of cranes and other lifting appliances with suspended loads as defined in ISO 7363. This standard is complementary to ISO 4310 and is intended for the types of cranes specified therein. The standard focuses on reliable, repeatable measurement practice to support performance verification, commissioning and safety compliance.

Key Topics

• Scope and applicability: Measurement of linear and angular velocity and associated time parameters for suspended-load lifting appliances consistent with ISO 7363 and ISO 4310.
• Test conditions: Tests must be carried out under the conditions specified in ISO 4310. Systems and mechanisms should be checked for correct unloaded operation prior to measurement.
• Measurement devices and accuracy: Measuring instruments must meet the precision requirements of ISO 9373 and applicable national specifications. The standard requires appropriate selection of devices and adherence to accuracy tolerances referenced in ISO 9373.
• Test procedure:
  • Perform preliminary test cycles to ensure correct operation of components.
  • Measure maximum, minimum and intermediate velocities and corresponding time parameters, as appropriate, under loaded and unloaded conditions.
  • Determine linear velocity from time measurements over the measured length of travel; determine angular velocity from time measurements over the measured arc. Parts of motion involving acceleration and deceleration are to be excluded from the calculations.
• Recording results: Results must be recorded and can be presented in example formats (Annex A, Tables A.1 and A.2) for linear and angular velocity measurements.
• Test report content: The report must include equipment identification, manufacturer, serial number, date, test conditions, measurement devices and methods, test configuration, measured results (tabulated), and the supervising tester's name.

Applications

ISO 13202:2003 is applicable to:

• Commissioning and acceptance testing of cranes and lifting appliances.
• Periodic inspection and maintenance verification to confirm performance parameters.
• Safety and regulatory compliance checks where validated velocity/time data are required.
• Quality assurance and factory testing when integrated with ISO 7363 equipment specifications.

Benefits include improved measurement consistency, traceable test records, and clearer communication of test results between manufacturers, owners and inspectors.

Related Standards

• ISO 4310 - Code and test methods for lifting appliances (test conditions and general procedures).
• ISO 7363 - Technical characteristics and acceptance documentation for cranes and lifting appliances.
• ISO 9373 - Requirements on measurement accuracy for parameters used during testing.

For practical implementation, follow the referenced ISO documents together: ISO 4310 for test conditions, ISO 7363 for equipment configuration, and ISO 9373 for measurement precision.
