Summary of Regulations
In order for a package to be considered child resistant, it must be tested with children ages 42-51 months using the protocol detailed in 16 CFR 1700. Testing is performed to ensure that young children are unable to access potentially dangerous substances. Each package is tested with at least 50 children (and a maximum of 200 children) to determine the effectiveness of the package.
In addition, the package must also be tested with senior adults (ages 50-70 years) to make sure it is not too difficult to use. For this portion of testing, at least 90% of the adults tested must be able to successfully open and, if applicable, re-close the package two sequential times within the allotted test periods.
