ISO/FDIS 282 is an International Organization for Standardization (ISO) Final Draft International Standard (FDIS) on conveyor belts - Sampling. It specifies how many samples to take for acceptance tests on a batch of conveyor belts, based on the total length ordered by the same user. In practice, it is used to set a consistent sampling plan for belts with the same characteristics, such as quality and width.

What does ISO/FDIS 282 specify?

ISO/FDIS 282 covers sampling for acceptance testing of conveyor belts. It applies when the belts form a batch with the same characteristics and the decision is based on the overall length ordered.

The document is organized into five clauses:

• Clause 1 - Scope
• Clause 2 - Normative references
• Clause 3 - Terms and definitions
• Clause 4 - Specification
• Clause 5 - Sampling

Clause 2 states that there are no normative references. The document therefore stands on its own for the sampling rules it sets out.

What are the key requirements of ISO/FDIS 282?

ISO/FDIS 282 sets the sampling plan by ordered length, then adds rules for how to take the samples from the rolls. For anyone planning acceptance tests, the key point is that the number of samples is fixed by the order size and the way the belts are packed into rolls.

• Clause 1 limits the document to acceptance tests on conveyor belts ordered by the same user. This matters because the sampling plan is intended for receipt or contract checks, not for every possible belt test.
• Clause 4 links the number of samples to the total ordered length through Table 1. In practice, the test plan starts with the order size, not with a guess made by the tester.
• Clause 4 says that when the number of individual rolls is less than or equal to the required number of test samples, one test piece is taken from every roll. This gives full coverage when the order is small.
• Clause 4 says that when there are more rolls than required samples, the rolls are selected at random and only one sample is taken from each selected roll. This is meant to avoid bias in the selection.
• Clause 4 also adds extra samples for very large orders above 10 000 m, with one additional sample for each further 5 000 m. For larger orders, the inspection burden rises with the length supplied.
• Clause 5 requires test samples to be full belt width and long enough for all requested tests. That means the sampler must provide material suitable for the full test program, not just a narrow strip.
• Clause 5 says any extra length needed for the samples is included in the total order length. Buyers and producers therefore need to allow for sampling material when planning the order.

What terms does ISO/FDIS 282 define?

Clause 3 formally defines acceptance test and roll, and the sampling rules also rely on a few operational terms.

• Acceptance test - a test carried out in the producer’s laboratory, by or on behalf of the producer, purchaser or user, to check conformity with the contract.
• Roll - a single length of conveyor belt material wound in spiral form after production to make storage and handling easier.
• Batch - the set of conveyor belts treated together for sampling because they have the same characteristics, such as quality and width.
• Test piece - the piece taken from a roll and used for the acceptance test samples required by the document.

Who uses ISO/FDIS 282?

ISO/FDIS 282 is used by conveyor belt producers, purchasers and users when they need to agree how many samples to take from an order. It is also relevant to laboratory staff and quality personnel who carry out or witness acceptance tests.

In procurement and quality control, the document helps people decide how many rolls to open, how to choose them at random, and how much material must be set aside for testing. That makes it useful whenever a belt order is checked against a contract.

What changed in ISO/FDIS 282 from the previous edition?

ISO/FDIS 282 is the third edition and cancels and replaces ISO 282:1992. The stated changes are the inclusion of the definition for “roll” in Clause 3, a revised sampling specification, and a revised Table 1.

What does the ISO/FDIS 282 document contain?

ISO/FDIS 282 contains the scope, definitions, a specification for sample numbers, and a sampling clause that explains how to take the test pieces. Table 1 gives the sample count by total ordered belt length, while Clause 4 adds the rules for multiple rolls and for larger orders.

Clause 5 describes the physical form of the samples: full-belt-width pieces with enough length for all requested tests. The document also states that extra sample length is part of the total order length, which is important when planning production, testing and acceptance.
