The design of this revised standard is based on the original professional standard and is implemented according to the product quality situation of the selected industry. The product quality may be affected by the influence of species, climate, etc. According to the measured data, this standard is revised at the following points: The original chemical method for measuring the content of aromatic alcohol in the sample is changed to the gas color method, which can more accurately reflect the content of aromatic alcohol.
2, the source of the alcohol is 0% (/V) technical alcohol: changed to: Appendix A in the standard.
This standard is issued by the Quality Standards Department of China Light Industry General Association. This standard is under the jurisdiction of the National Fragrance Standardization Center. The starting unit of this standard: Fujian Fragrance Cosmetics Industry Association. The main drafters of this standard are Chen Xian, Jinxiu County, Hangzhou, and Shimei. The implementation of this standard is based on the professional standard ZTY4-6 issued by the Ministry of Light Industry of the People's Republic of China. This standard defines the technical requirements for white orchid leaf oil. Test methods and test period are included. Q8/T 2239.-16

6.1 The manufacturer guarantees that the products meet the requirements of technical standards. Each batch of products is accompanied by a quality certificate, including: manufacturer name, product name, trademark, production date, batch number, net weight, product compliance certificate and product number. 6.2 The acceptance unit has the right to inspect whether the products meet the requirements of the standard. One batch is selected for one acceptance, and no separate acceptance is required.
8.8 Sampling method: G3/T: 4455.2, the minimum volume of the product is 1mL. Each packaging unit is discarded: less than 200 pieces, more than 200 pieces Take two samples of 1ce oil. Take 0~[ccm3mL with a sample tube, mix all the white oil samples in a sampler, take 50~1cm3 of them and put them into a blue glass bottle, and then put them into a blue glass bottle. The name of the manufacturer, product name, number of samples and sampling date. "Bottle inspection, service: keep them separately. 64 If one of the measures in the acceptance results does not meet the requirements of this standard, the production department will re-examine the samples from the 2 times the amount of packaging together with the production department. If the re-examination results are still unqualified, the batch of products will be judged to be unqualified. 6 When the supply and demand parties have different opinions on the product, they can reach an agreement to resolve the problem. The second element is cut 7 standard, full packaging, transportation, storage
