ISTA Test Procedure 2C is a partial simulation test for individual packaged furniture products, also known as case goods.  Although the traditional furniture definition of case goods is for hard goods and not upholstered furniture, it can be used for any furniture transported in a container.

For ISTA 2C, the shipper must determine the following prior to testing:

  • What constitutes damage to the product and
  • What damage tolerance level is allowable, if any, and
  • The correct methodology to determine product condition at the conclusion of the tests and
  • The acceptable package condition at the conclusion of the test.

The ISTA 2C test blocks that follow contain tables that indicate the required steps for each test in the procedure.
