In which, for IS-IT, IL-IT type sodium hydroxide and sodium chloride, they are the exit- factory inspection items of type inspection items; the rest are sampling items of type inspection items. For IS-DT, IS-CT, IL-DT and IL-CT type sodium hydroxide, sodium carbonate, and sodium chloride, they are the exit-factory inspection items of type inspection items; the rest are sampling items of type inspection items. If there are following conditions. the resumption from production shutdown, the production process has changed significantly (such as materials, process conditions, etc.), contract requirements, etc., it shall conduct type inspection. Under normal production conditions, type inspection shall be conducted at least once a month. 7.4 Before sodium hydroxide products are factory-exited, it shall be inspected by the manufacturing enterprise’s quality supervision & inspection department, and attached with quality certificate. The content includes. manufacturer name, product name, model specifications, quality indicators, grade, batch number or production date, the implemented standards.
