6 Inspection rules
QE 1778-93
6,1 Each batch of ethylhexanoate products shall be technically inspected by the inspection department of the manufacturer. The manufacturer shall ensure that the products meet the requirements of this standard: Each batch of products shall be accompanied by a quality certificate, which shall include: manufacturer name, product name, trademark, export date, batch number, purity, product certification and standard number. 6.2 Inspection form should be made according to this standard to check the quality of the products received. Each batch number should be inspected once, and different batch numbers should be inspected separately. B.3 For each batch of packaging units, two bottles should be collected if the number is less than 1 barrel (bottle), and three barrels (bottles) should be collected if the number is more than 14 barrels (bottles). Take the packaging from the laboratory, check the moisture and impurities, and then heat the sample tube for 5-10 μm: the sample is fully dried and the sand is uniformly discharged. The manufacturer, product name, batch number, quantity and collection period are listed on the sample, one for inspection and the other for confidential storage.
. If any indicator does not meet the requirements of this standard, the production station may stop the production and re-inspect the product. If the re-inspection result still indicates that it is not qualified, the batch of products cannot be accepted. 6.5 If the parties have any objection, they may decide to solve the problem or invite a legal inspection agency to do so, and the party shall bear the cost.
6. Color, acid value, desorption capacity are factory inspection indicators, relative density, optical density, and solubility are type inspection indicators, and inspection shall be conducted once a quarter.
Marking, packaging, transportation, and storage
7.1 The following iron barrels or packagings should be marked with: product name, manufacturer name, trademark, approval letter, and packaging letter. If the investment unit has special requirements, please discuss and negotiate with the manufacturer. 2. During transportation, the product should be protected from exposure to sunlight, rain, and heat, and should not be mixed with aldehydes. 7.3 The product should be stored in a dry, ventilated, and shaded warehouse. Prevent air pollution and transport away from fire sources. A

A Determination of column efficiency
A Name.1 Chemical properties test
The test shall be carried out according to the method specified in Article 3, 1 of GB1153, and the general requirements shall be met.
A3.2 Column efficiency
The column efficiency shall be measured by the percentage method specified in Article 8.2 of GD11%B0. A4 Determination method
The internal normalization route shall be carried out according to Article 19, and the specified method shall be carried out. A5 Complexation and result expression
The test shall be carried out according to Article 11.4 of G11338, and the result shall be met. The standard is proposed by the Quality Standards Department of the Ministry of Light Industry. This standard is issued by the Shanghai Spice Factory under the supervision of the Shanghai Spice Factory and the Jiang Spice Factory. The main drafter of this standard is Luo Xilin. This standard is equivalent to the American Association of Standards E0A No. 172. From the date of implementation of this standard, the former Ministry of Light Industry standard Q866-83 is used as the standard for ethyl acetate.
