Check for any visible defects on the surface of the nipple bag, such as bubbles, cracks, stains, etc.
Physical Performance Inspection
Abrasion Resistance Test: Conduct friction tests to assess the nipple bag's resistance to abrasion, ensuring it does not wear out quickly during extended use.
Pressure Resistance Test: Apply a certain amount of pressure to test the deformation and pressure resistance of the nipple bag.
Chemical Performance Inspection
Food Contact Safety Inspection: Test if the nipple bag releases harmful substances when in contact with food, such as BPA, heavy metals, etc.
pH Value Inspection: Test the acidity or alkalinity of the nipple bag material to ensure it does not affect the pH of the food during use.
Dimension Inspection
Measure the length, diameter, and other dimensions of the nipple bag to ensure compliance with standard size requirements.
Service Life Inspection
Simulate usage conditions to test the service life of the nipple bag, such as whether it ages after multiple sterilizations.
Temperature Deformation Test
Test the deformation of the nipple bag at different temperatures to ensure it does not deform or deteriorate within the normal temperature range of use.
Inspection Standards
GB 4806.7-2016 National Food Safety Standard - Plastic Food Contact Materials and Products:
This standard applies to the production and processing of plastic food contact materials and products, including nipple bags. It includes requirements for material safety, physical performance, chemical properties, etc.
GB/T 17213-2014 Baby Bottles and Nipples:
This standard specifies the technical requirements, test methods, inspection rules, packaging, labeling, transportation, and storage for baby bottles and nipples.
ASTM F963-17 "Toy Safety Standard":
Although it is a toy safety standard, it also includes safety requirements related to infant products, which can be used as a reference standard.
ISO 18373:2015 Infant Toys:
This is an international standard for infant toys, which also includes safety requirements and testing methods for baby products.
The above-listed inspection methods and standards are important measures to ensure the safety and quality of nipple bags. Manufacturers should strictly adhere to these standards during production to ensure that the products meet the relevant national and international requirements.
