6 Inspection rules
QB1954-94
6.1 Ethyl propionate shall be inspected by the technical inspection department of the manufacturer. The manufacturer shall ensure that all products leaving the factory meet the requirements of this standard. Each batch of products leaving the factory shall be accompanied by a quality certificate, which shall include: manufacturer name, product name, production date, batch number, net weight, product quality certificate of compliance with this standard and standard number. 6.2 The acceptance unit has the right to inspect whether the quality of the received products meets the requirements of this standard in accordance with the provisions of this standard. Each batch number shall be inspected once, and different batch numbers shall be inspected separately. 6.3 For each batch of packaging units, two barrels (bottles) shall be selected for less than 100 barrels (bottles), and three barrels (bottles) shall be selected for more than 100 barrels (bottles). When opening the package for sampling, the appearance should be checked for moisture and impurities, and then shake to mix thoroughly. Then use a glass sampling tube to absorb 50-100 mL of the sample. Inject into the sample mixer and mix evenly, and put into two clean, dry glass bottles with ground stoppers. Indicate the manufacturer's name, product name, batch number, quantity and sampling date on the bottles. One bottle is used for inspection, and the other bottle is kept for reference. 6.4 If one of the indicators in the acceptance results does not meet the requirements of this standard, the manufacturer can re-examine the sample from twice the amount of packaging together with the manufacturer. If the re-examination results still show unqualified indicators, the batch of products cannot be accepted. 6.5 When the supply and demand parties have objections to the product quality, they can resolve them by agreement or by arbitration by the statutory testing agency. The cost shall be borne by the investor.
7 Marking, packaging, transportation and storage
7.1 Ethyl propionate is packed in iron barrels or glass bottles. The packaging is marked with: food additive product name, manufacturer name, batch number, net weight, tare weight, date of manufacture, this standard number and the "flammable goods" mark in GB190. If the ordering unit has special requirements, it can make a separate agreement with the manufacturer. 7.2 This product should be stored in a dry, ventilated and cool warehouse to prevent contamination by foreign air and keep away from fire sources. Transportation must comply with the regulations of relevant departments.
7.3 This product has a shelf life of one year if it meets the specified storage and transportation conditions, the packaging is intact and has not been opened. Additional instructions:
