Shenzhen Jingzhuoke Chemical Technology Talks about the Inspection Standards of Industrial Sulfuric Acid

Industrial sulfuric acid is different from ordinary sulfuric acid. Its quality must meet the corresponding requirements before it can produce qualified products. Therefore, it needs to be inspected before use. Let me share with you the inspection standards of industrial sulfuric acid. , Hurry up and take a look with me.

1. The inspection of industrial sulfuric acid products produced from sulfate ore and sulfur as raw materials is divided into two types: factory inspection and type inspection. All items of type inspection of factory inspection items. Under normal circumstances, a type inspection should be carried out every month.

2. Batch-based inspection Take each storage tank as a batch of products and carry out sampling according to regulations. The total sample volume of each batch shall not be less than 500mL, and after mixing, the samples shall be placed in clean, dry glass bottles with ground stoppers, and the labels shall be marked on the bottles to indicate the name of the manufacturer, product name, batch number, category, grade, sampling Date and name of sampler, etc.

In the process of testing industrial sulfuric acid, if there is one item that does not meet the standards, under normal circumstances, double the amount of samples will be taken again for testing. If there is one item that is unqualified, the product will not be allowed to be put on sale, that is to say, the manufacturer must follow the national standard. Carry out manufacturing and safeguard the rights and interests of consumers.
