Some standard content:
Chapters 4 and 5 of this standard are mandatory, while the rest are recommended. 6B19193-2003
Although my country is under great pressure in controlling the occurrence and spread of infectious diseases, the occurrence and spread of infectious diseases are still under pressure. Viral hepatitis and other venereal diseases, transaminase, tadpoles and other sexually transmitted diseases have an increasing incidence in some local areas, and there are also potential causes of AIDS. Therefore, it is very important to do a good job in timely and effective elimination of the source of infection, eliminate the source of infection, and interrupt the spread of the disease. Controlling the occurrence and spread of infectious diseases is necessary. This standard is formulated in accordance with the measures for the implementation of the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases, the Measures for the Implementation of the Law of the People's Republic of China on the Prevention and Control of Infectious Diseases and the Disinfection Management Measures of the Ministry of Health of the People's Republic of my country. In the process of this standard, in addition to referring to actual domestic and foreign data, it also made full use of China's experience and research results in the treatment of infectious diseases and disinfection of epidemic sources over the years. This standard is a normative standard proposed by the Ministry of Health of China. The drafting units of this standard are: Four Health Stations, Fan City Health Station, Yangling City Health Station. The main contributors are: Zhang Jun, Liu Hengchuan, Wu Le, Ye Dumao, Hua Kun, Gao Honglie, etc. 1 Scope

.....( H.4)1. The disinfection effect evaluation is to directly check whether there are pathogens on the disinfected items, but some pathogens are difficult to distinguish. It is necessary to use the indicator biological control method. B.1.2 Every time the disinfection is carried out, there should be a disinfection inspection record or form, which must record the sample source, number, inspection index, sampling date, sampling information, inspection results, inspection and verification personnel's signature, etc. B.1.3 Objects of disinfection effect inspection: Articles: surfaces, clothing, excrement, secretion, vomiting, air, etc. 8.1.4 Evaluation of disinfection effect must be carried out on the same disinfectant. Use a neutralizer or neutralization method that has been proven to be effective in the neutralization test. B.2 Samples and sample processing
B.2.1 Samples are collected from the body surface using a standard plate, and the surface is smeared with a wet cloth. Cut off the part that is in contact with the disinfectant, and put it in the neutralizer. The disinfectant used is listed in the neutralizer list. After neutralization for 1C, shake it or use a standard homogenizer to mix it for later use. B.2.2 Excrement 10g or 10ml of the sample is added with 1U0mL of saline solution, filtered through a homogenizer and cultured in a slurry. B.2.3 Gas sample results shall be carried out according to 1.1 method in Appendix 1 of B15073-1095. B.2.4 Waste water and waste filtration shall be carried out according to 6R978.
