Toy Templates A, B, and C are specialized test fixtures used to determine whether rattles intended for infants up to 18 months of age present choking or suffocation hazards. During testing, the rattle is placed into the opening of the test template. If any part of the rattle passes completely through the opening without the application of force (push or pull), the product is considered to have failed the safety requirement.

For rattles incorporating nearly spherical, hemispherical, or circular flared ends, a Supplemental Rattle Test Fixture is used to conduct additional safety evaluation. These templates are essential tools for toy safety laboratories and manufacturers to ensure compliance with infant safety standards and prevent choking risks.
