Food physical and chemical testing refers to the use of chemical analysis methods and devices to conduct food quality and safety testing. The process mainly includes a series of processes such as application acceptance, test method preparation and confirmation, sample collection and disposal, test process control and result confirmation and reporting. This standard is mainly applicable to food physical and chemical testing laboratories engaged in food quality (including sensory and physical and chemical) and chemical substances (including active ingredients, pesticide and veterinary drug residues, food additives, heavy metals, toxins, environmental pollutants, etc.) testing. Chemical testing laboratories engaged in food contact material testing and other fields can refer to this standard. This standard specifies the management requirements, technical requirements, process control requirements and quality assurance requirements for the quality control of food physical and chemical testing laboratories. This standard is applicable to the quality control of food physical and chemical testing laboratories engaged in food quality (including sensory and physical and chemical) and chemical substances (including active ingredients, pesticide and veterinary drug residues, food additives, heavy metals, toxins, environmental pollutants, etc.). Chemical testing laboratories in other disciplines can also use it as a reference. The preparation of this standard is mainly based on GB/T27025 "General requirements for the competence of testing and calibration laboratories", and absorbs the content of GB/T19001-2000 "Quality Management System Requirements", refers to the documents of relevant international professional organizations, applicable contents in domestic and foreign industry standards and professional literature, and fully integrates the management experience of relevant domestic laboratories. This standard aims to standardize, guide and help relevant laboratories to meet the specific requirements of GB/T27025 and quality control in this professional field.
