When the top part cannot be sampled and the material is relatively uniform, sampling can be done at the discharge port of the tanker. The sampler should be made of glass or polyethylene plastic. The sample volume taken shall not be less than 500mL. After mixing, place in treated clean, dry hard glass bottles or polyethylene bottles. A label should be attached to the bottle to indicate: manufacturer name, product name, specifications, grade, batch number and sampling date. If any indicator in the inspection results does not meet the requirements of this standard, samples should be taken from twice the number of packaging barrels for 6.5
verification. If even one indicator in the verification result does not meet the requirements of this standard, the entire batch of products will be deemed unqualified. 6.6 When the supply and demand parties have objections to product quality, they shall be handled in accordance with the provisions of the "Interim Measures for National Product Quality Arbitration and Inspection". Marking, packaging, transportation, storage
7.1
Industrial hydrogen peroxide is packaged in polyethylene barrels, aluminum barrels or aluminum tank trucks. There should be vent holes on the lids of various packaging containers. Packed in polyethylene drums, the net weight of each piece does not exceed 50kg; packed in aluminum drums, the net weight of each piece does not exceed 100kg. 7.2
Each batch of packaged finished products should be accompanied by a quality certificate in a certain format. The content includes: manufacturer name, product name, specifications, etc. 7.3
grade, batch number, production date, net weight and this standard number. Packaging containers should be firmly marked. The content includes: manufacturer name, product name, specifications, grade, production date, batch number and 7.4
net weight, this standard number and its trademark.
7.5 Industrial hydrogen peroxide products are strong oxidants and corrosive. The packaging container should be painted with the "Figure 9 Oxidizer Mark" and "Figure 18 Corrosive Materials Mark" specified in GB190, as well as the "Figure 3 Upward Mark" specified in GB191. GB1616-88
Industrial hydrogen peroxide should be stored in a cool and ventilated place. During storage and transportation, avoid sunlight or heat. Cannot be mixed with flammable 7.6
products and reducing agents. If the container breaks or leaks, flush it with plenty of water. Additional notes:

6.4.1 When industrial hydrogen peroxide is packed in barrels, if the total number of packaging barrels is less than 500, the number of sampling barrels shall be selected according to the provisions of Table 2; if it is greater than 500, the number of sampling barrels shall be selected according to 3VN (N is the total packaging number of barrels). When loading by tanker, select from each tanker. Total number of packaging barrels
