A cot or a pushchair is designed against a written standard rather than against general good judgement. Understanding how those documents are produced explains both their strengths and their gaps.
Standards start from recorded injuries
Committees draw on injury surveillance data, recall records and incident reports to identify how children are actually being hurt by a category of product.
Each identified mechanism becomes a requirement. Gaps that trap fingers, slats spaced widely enough to trap a head, and small components that detach are all responses to documented cases.
This makes standards retrospective by construction. They encode what has already gone wrong, which is thorough for established categories and thin for new ones.
Requirements become laboratory tests
A requirement is only useful if it can be verified identically in different laboratories, so each becomes a procedure with specified forces, dimensions and durations.
Small parts are checked against a cylinder representing a young child's throat. Structures are loaded repeatedly to simulate years of use. Fabrics are tested for how they burn.
The tests are deliberately mechanical and reproducible, which means they measure defined hazards rather than assessing whether a product is broadly sensible.
Mandatory and voluntary standards differ
Some standards are written into law, and a product failing them cannot legally be sold. Others are voluntary, and compliance is a commercial decision rather than a legal requirement.
Which categories fall into which group varies between countries, and a product legally sold in one market may not meet the mandatory requirements of another.
Marks and certification labels also differ in meaning. Some indicate independent testing, while others are a manufacturer's own declaration of conformity.
New categories arrive before the standard
Products that do not fit an existing category can be sold before any specific standard exists, tested only against general safety requirements.
Standards for genuinely new types of product typically follow the product to market by a considerable period, because the committee process is slow and evidence has to accumulate first.
This is the structural reason novel sleep, carrying and monitoring products have repeatedly been withdrawn after reaching households in large numbers.
What a standard does not promise
Compliance means a product passed defined tests under defined conditions. It says nothing about misuse, worn components, missing parts or use outside the intended age range.
Assembly is a common failure point, since a correctly designed product assembled incorrectly may fail in exactly the way the standard was written to prevent.
Instructions and weight or age limits are part of the certified design rather than suggestions, and equipment used outside those limits is outside what was tested.
