I was bathtub toys for the bathtub toys competition and it dawned on me that I wanted the kiddos to be safe and issue advisories for potential choking hazards! I wanted a little tester like at the airport for carry on's (lol) so I could just off hand see if parts were safe, so this was born. Hope it helps you too.

Keep in mind this doesn't take into account sharp corners on objects, objects that have holes otherwise that would allow airflow etc. etc. .. this tool is just a little baseline for your consideration. More or less, if an individual part completely fits in the tester.. uh oh.. it might cause a little one to choke.

These dimensions are according to CHATGPT4 (full conversation below ;TLDR). I can't stress that enough (for personal liability reasons!) and I've pasted the entire conversations below. Looking at it in hand I think it's a sound baseline and honestly impressive work on the GPT's part.

FYI: I found another similar model said to be for US regulations. The maker said ‘The part is not a choking hazard if parts protrude from the top surface.’ I have added text to the surface (they need it, I'd never remember what these were just laying around the workshop!) and included that model as well in the downloads.

Post makes and leave feedback if you know something that's helpful for the community, it's an important subject matter!

CHATGPT4 CONVERSATION 22 FEB 2014.

You

is there an international standard for small parts for children for non choking?

ChatGPT

Yes, there are international standards for small parts in children's toys to prevent choking hazards. These standards vary by region but have similar goals to protect children from choking risks associated with small parts in toys.

For children up to and including 36 months of age, the international standard ISO 8124-1:2022 outlines safety aspects related to mechanical and physical properties of toys. This standard is recognized in Australia under AS/NZS ISO 8124.1:2023, and it requires toys to be designed, manufactured, and labeled to prevent small parts from causing choking, suffocation, or death during play or after reasonable wear and tear.

In the European Union, the EN 71-1 standard, harmonized under the Toy Safety Directive, specifies requirements for toys containing small parts intended for children under 36 months. It includes criteria for toys that are intended to be put into the mouths of children, highlighting that such toys should not contain small parts that may cause choking hazards.

Australia's mandatory toy safety standards, enforced by the Australian Competition and Consumer Commission (ACCC), align with the Australian/New Zealand standard AS/NZS ISO 8124. This includes specific sections derived from the voluntary standard for toys for children up to and including 36 months of age. This standard aims to address choking hazards caused by small parts either by design or as a result of wear and tear.

These standards emphasize the importance of designing and constructing toys in a way that minimizes the risk of small parts becoming choking hazards. They also include requirements for labeling to ensure caregivers are aware of potential risks. Manufacturers and suppliers must ensure their products comply with these standards to sell toys in these regions safely.

I want to create a tester box like that are at the airports for a good general rule of thumb for 3d designers. what should the interior dimensions be to cover most of the international standards?

ChatGPT

To create a tester box that aligns with international safety standards for toys, it's essential to consider the dimensions specified for the small parts cylinder used in safety tests. While the specific dimensions of the small parts cylinder were not directly found in the sources reviewed, such standards typically define a cylinder to simulate the size of a child's throat. Historically, this has been around 31.7 mm in diameter and 25.4 mm in depth, but you should verify the current ISO 8124-1:2022 or similar standards to ensure accuracy. This would provide a good general rule of thumb for designing toys intended for children under 36 months to prevent choking hazards. For the most accurate and up-to-date dimensions, referring directly to the ISO 8124-1:2022 standard is recommended.

You

can you give me a direct citation for the 31.7 diameter and 25.4 depth

ChatGPT

The dimensions I mentioned for the small parts tester cylinder, 31.7 mm in diameter and 25.4 mm in depth, are commonly referenced in discussions about toy safety but were not directly cited from the sources I accessed. For precise and officially cited dimensions according to the latest international safety standards for toys, it's best to consult the actual text of the ISO 8124-1:2022 standard or similar regulatory documents.

You

give me one source I can use where it is mentioned in discusion

ChatGPT

A commonly referenced source for discussions around toy safety and the dimensions of a small parts tester is the U.S. Consumer Product Safety Commission (CPSC). The CPSC specifies a small parts test fixture that reflects these dimensions to prevent choking hazards for children under three years of age. For detailed specifications and guidelines, directly consulting the CPSC's guidelines or the ISO 8124-1:2022 standard would be recommended.

You

i need a link where i can see those dimension so i can cite it in the printables listing

ChatGPT

For accurate dimensions of the small parts tester, directly referring to the U.S. Consumer Product Safety Commission's (CPSC) guidelines on toy safety would be the most authoritative source. You can find this information on the CPSC's official website, where they provide detailed safety standards and testing methods for toys, including the specifications for small parts to prevent choking hazards for children under three years of age.
