GB/T5009.72—2003
This standard replaces GB/T6009.72—1996 Analysis method for aluminum high-end and high-end sanitary special standard 3. The main functions of this standard are as follows: According to BT0001.4-2C5. Standard Part 4: Chemical analysis method, the original standard was revised.
This standard was proposed and approved by the Ministry of Health of the People's Republic of China. This standard was first issued in 1995 and revised for the first time in 19864. This is the second revision. 534
1 Scope
Analysis method for hygienic standard of aluminium containers GB/T 5C09.72—2003
Specifies the hygienic indicators of various tableware, eating utensils and containers made of aluminium as raw material through stamping or casting.
This standard is mainly used for analysis of hygienic indicators of food storage services.

For all the cited documents beyond the legal date, all subsequent amendments (excluding errata) shall apply to this standard. However, for the purpose of research and development based on the standard, the latest versions of these documents shall be used. For all documents without an errata note, the latest version shall apply to GB/T 5(S.11-20) 3 Definition of Total and Inorganic Foods GRT 514-23 Food standard
GB/T509.1233 Food standard analysis method GH11333 Food standard 3 sampling method
According to the number of products, the sample is produced in small batches, and each time a number of samples are collected, the product name, batch and sampling period are noted respectively. One half of the sample is for testing, and the other half is kept for one week and one month, and is prepared for secondary analysis. 4 External inspection and avoidance indicators
The shape of the container is even, the surface is smooth, and the packaging is uniform. Spoon wave, secretion spot, fixed part of the large cell. It should comply with the provisions of 6K11333: 5 diffusion parts

% take glacial acetic acid or 35% acid! To 1
5.2 Diffusion method
First brush the test tube with fertilizer, rinse it with self-water, wash it with steamed water, dry it for later use, take two pieces from each batch, add acetic acid (1> to 5 "ml from the upper edge, heat it to 30rmim, keep it boiling, and add acetic acid (-%) to record it. Volume, after 24h at room temperature, pour 1 bottle of disinfectant into the instrument for trial use, fill it up to 5 places from the mouth, add 2mL and place it at room temperature. The volume of the insensitive body is calculated by multiplying 2mL per square meter of the core area. The instrument is divided into several parts, and the total volume is calculated. If the entire instrument is filled with liquid, it is calculated on both sides. The volume of the added liquid should be multiplied by 26.
