What is a check test?

There are two types of Check Test.

The first involves verification of documentation and calculations forming the basis of the Certificate on which a doubt or query has been raised and, if possible, a set of additional measurements made, in accordance with the same standard IWTO Specification (test method) as was adopted for the original test, on that portion of the sample remaining after that original test. Where no sample remains, a Recore Check Test may be carried out as part of the check testing procedures. Check testing is restricted to tests carried out by the Test House that conducted the original test.

The second type of retest is a Recore Check Test. This is a set of measurements made , in accordance with the relevant IWTO Specifications (test methods) and Regulations, on a further sample of raw wool drawn from the delivery or lot as part of check testing procedures. A Recore Check Test may only be conducted where a Certificate has not been delivered in relation to a contract. This means that wool growers or wool buyers cannot request Check Tests after their wool has been sold.

Check testing is restricted to tests carried out by the Test House that conducted the original test.
