4 Technical requirements
4.1 General requirements
4.1.1 Components
4.1.1.1 Appearance
It shall be clean, neat, without foreign objects. There shall be no gaps, holes,
or deformations that affect the use (except for design requirements).
4.1.1.2 Edge and tip
The feeding bottle and its components shall not have sharp edges and sharp
tips that may cause injury or danger.
4.1.1.3 Ink adhesion of printing pattern
For reuse products or components, the ink adhesion of the marked printing
pattern (including text and numbered graduations) shall meet the requirements
When tested according to 5.2.2.6.1, the components of the feeding bottle
(including teat or drinking accessory) shall not protrude from the bottom of the
test template A / template B.
If the teat or drinking accessory protrudes from the bottom of the test template
A / template B, it shall meet the requirements of 4.1.2.6.2.
If the components of the feeding bottle (excluding teat or drinking accessory)
protrude from the bottom of the test template A / template B, it shall meet the
requirements of 4.1.2.6.2.2.
4.1.2.6.2 Other requirements for teat or drinking accessory
