This paper explains the services rendered by the Canadian Standards Association (CSA) as a national standards writing body and as a testing laboratory. The paper shows how CSA certified that a given product line or system meets a specified standard once a prototype has been satisfactorily tested to the requirements of that standard.
The historical development in Canada of child-resistant packaging is related with the development in the United States of the “child-adult test protocol.”
The need for scientific test measurements of the anthropometric forces used in opening and closing child-resistant packages is explained. The use of these scientific test measurements has enabled the CSA to certify that packages in the marketplace are effectively identical to those originally submitted to the child-adult protocol test.
Several provincial governments in Canada have mandated the CSA certification of child-resistant packages. In so doing, these governments have established a “preclearance” of a package's child resistant and adult use capabilities. Otherwise, the need to prove compliance or non-compliance of the package's intended integrity in the marketplace remains a burden-some and difficult problem of resolve.
