（China）YY NH225 Yellowing Resistance Aging Oven
Summary:
It is manufactured in accordance with ASTM D1148 GB/T2454HG/T 3689-2001, and its function
is to simulate the ultraviolet radiation and heat of sunlight. The sample is exposed to ultraviolet
radiation and temperature in the machine, and after a period of time, the degree of yellowing
resistance of the sample is observed. The staining gray label can be used as a reference to
determine the grade of yellowing. The product is affected by sunlight radiation during use or the
influence of the container environment during transportation, resulting in the color change of the
product.
