CCCR 2001- What is a Leak Test?


By: Ivy Tang, Product Safety Specialist, email

Containers holding liquid chemicals must pass the Leak Test, as laid out in Schedule 3 of the Consumer Chemicals and Containers Regulations, 2001.  While not every container in a production lot needs to be tested, it is important to ensure that leakage does not occur, as it may harm the consumer. It is important to note the following:

  • The test must be completed on the product as it is sold to the consumer. You cannot substitute a different liquid or container.
  • Empty containers that are intended to store or dispense the product, must also be tested.
  • The test takes into account containers that are meant to release fumes or vapors.
  • Single-use containers are exempt from this test after opening. This is why single-use containers have specific labeling requirements.

To conduct the leak test, the sample is inverted at 45° below the horizontal, over a piece of blotting paper. The containers must be temperature-conditioned. Any seals must be removed, and the closure must be in the lowest possible position. After an hour, the paper is examined for evidence of contact with liquid. The leak test is a pass-fail test. Upon failure, the entire production lot is considered to have failed as well.

Other similar tests include aging or life tests, which ensure containers are still compliant over the course of their shelf life. Such tests may also be conducted to support packaging requirements for transport.

Make sure your containers pass this important test, with the help of an ISO-accredited laboratory. Dell Tech can assist, along with ensuring that your labeling is compliant with CCCR 2001. Contact Dell Tech today and inquire about our testing capabilities and compliance services.
