What Methods Can Be Used To Determine The Quality Standard Of Latex Teether?
The methods for determining the quality standard of latex dental adhesive mainly include appearance inspection, size measurement, material inspection, chemical property test and safety test.
Appearance inspection: By observing the appearance of the latex teether, can be preliminarily judged its quality. Good quality latex gums should have a smooth surface, no obvious cracks or dents and other defects. In addition, can also feel whether the texture is even by touching the surface of the latex dental adhesive, , which is helpful to judge the quality of the production process and material.
Size measurement: to accurately measure the size of the latex teether, to ensure that it conforms to the specified standard size. This can be done by using measuring tools such as calipers, microscope, etc. to ensure that the latex teether will achieve the desired effect and safety when applied.
Material inspection: check whether the material of latex teether meets the standard, by smelling its smell, observe its color and texture and other ways. Natural latex products usually have a faint natural rubber tree scent, a milky matte color, surface will have a natural texture and irregular tear marks and some minor imperfections. In addition, can also be measured by the content of latex to judge its quality, good quality latex products latex content is basically more than 90%.
Chemical properties test: to evaluate the chemical properties of latex teether, including volatile compound content test, etc. Volatile compound content is tested according to relevant standards, such as GB28482-2012 " Safety requirements for infant and toddler pacifiers" , to ensure that the chemicals in latex dental adhesives do not have adverse effects on the health of infants and young children.
Safety test: for latex tether safety test, including parts separation test, to assess whether there is a risk of parts separation of latex products. If parts of the latex product are separated, separated parts may be swallowed by the baby, resulting in a risk such as suffocation. Therefore, testing the integrity of latex teether is also an important part of assessing its safety.
The above methods can be used to comprehensively evaluate the quality and safety of latex dental adhesive, to ensure that it complies with relevant standards and regulations, to protect the safety and health of consumers.
