ISO 282:1992

Overview - ISO 282:1992 (Conveyor belts - Sampling)

ISO 282:1992 defines sampling requirements for conveyor belts used in acceptance testing. The standard specifies how many samples to take from an order (batch) of conveyor belts depending on the total length ordered by the same user. It applies to batches of belts that share the same characteristics (quality, width, etc.) and supports consistent quality control and contract verification between purchaser and producer.

Key topics and requirements

• Scope: Number of samples for acceptance tests is determined by the total ordered belt length (L). Applicable when belts in the batch have the same characteristics.
• Sampling table (number of samples based on total length L):
  • L < 500 m: 1 sample
  • 500 < L < 1 000 m: 2 samples
  • 1 000 < L ≤ 2 000 m: 3 samples
  • 2 000 < L < 3 500 m: 4 samples
  • 3 500 < L < 5 000 m: 5 samples
  • 5 000 < L ≤ 7 000 m: 6 samples
  • 7 000 < L < 10 000 m: 7 samples
  • Above 10 000 m: add one sample for every additional 5 000 m
• Acceptance test definition: Tests conducted at the producer’s laboratory, by or on behalf of the producer or the purchaser, to verify compliance with contract requirements.
• Sample form and length:
  • Samples shall be of full-belt width and of sufficient length to perform all requested tests.
  • Additional length required for test samples must be included in the total order length.
  • The standard does not make a recommendation on the specific location on the belt from which samples should be taken.

Applications - who uses ISO 282:1992

• Manufacturers and producers of conveyor belts use the standard to plan and provide the correct number and size of test samples for acceptance testing.
• Purchasers and end users (mining, bulk materials handling, manufacturing, logistics) reference the standard when specifying contract requirements and verifying incoming belt quality.
• Quality assurance and testing laboratories rely on the sampling rules to ensure consistent, contract-compliant acceptance testing.
• Useful for procurement teams, contract managers, and engineers specifying belt orders and inspection routines.

Related standards

• ISO 282:1992 was prepared by ISO/TC 41 (Pulleys and belts), Sub-Committee SC 3 (Conveyor belts). For comprehensive belt specification and testing programs, consult other ISO standards on conveyor belts, testing methods and pulleys maintained by ISO/TC 41.
