发布日期：2021-11-05阅读量：12069发布者：超级管理员
According to the food safety law and its implementation regulations and the decision of the State Council on strengthening food safety, in order to implement the task of food standard cleaning and integration in the 12th Five Year Plan of the national food safety supervision system and the 12th Five Year Plan of the national food safety standards, in May 2014, The national health and Family Planning Commission issued the work plan for the integration of national food safety standards (2014-2015), which started the task of cleaning up and integrating food standards, including the integration of standards for food related products.
The health and Family Planning Commission takes the lead in integrating the current standards of food containers, packaging materials and other food related products according to the classification of food related products and the catalogue of food related product safety standards, so as to form the basic standards and product standards of food related products. By the end of 2015, the task of cleaning and integrating food related product safety standards has been successfully completed, and the new standard framework has been gradually formed and improved. The revised safety standards for food contact materials have also been released in 2015 and 2016.

Sample size
1. Filling sample: one sample is required for each project. (filling volume above 100ml) 2. Flake type sample: one sample is required for each project. (more than 100 square centimeters in area) 3. Corresponding volume type sample: one sample is required for each item with sealing effect (silicone ring, cover). (if the corresponding volume is more than 100ml, the customer needs to provide the corresponding volume) Note: if the single area or volume is insufficient, use multiple samples
Sample requirements
1. The sample quantity is calculated according to the finished product. If the volume of the finished product is too small, it is calculated according to the area; 2. Color mixing side is not accepted; 3. Single item retest is not accepted
Test cycle
Routine test cycle of migration test: contact time < 24h, 5D; Contact time = 24 hours, 7 days; Contact time = 72 h, 12 D; Contact time = 240 hours, 12 days; The accelerated test cycle is shortened by one day on the basis of conventional test cycle; The non migration test cycle is detailed in the specific project
