Test method
4.1 Determination of acephate content
Determination shall be carried out in accordance with the provisions of GB6698.
Approved by the Ministry of Chemical Industry of the People's Republic of China on November 18, 1991, and implemented on July 1, 1992
W.bzsoso, com4.2 Determination of water content
Determination shall be carried out in accordance with the Karl Fischer method in GB1600. 4.3 Determination of acidity
4.3.1 Reagents and solutions
4.3.1.1 Anhydrous ethanol (GB678): analytical grade. HG2211—91
4.3.1.2 Standard titration solution of sodium hydroxide (GB629): c(NaOH)=0.05mol/L, prepared and calibrated according to GB601. 4.3.1.3 Methyl red indicator solution: 2g/L ethanol solution. 4.3.2 Determination steps
Accurately weigh 1~2g of the sample (weighed to 0.0002g) in a 100mL conical flask, add 25mL of anhydrous ethanol (4.3.1.1), add 3 drops of methyl red indicator (4.3.1.3), and titrate with standard titration solution of sodium hydroxide (4.3.1.2) until the solution changes from red to yellow as the end point, and perform a blank test at the same time.
4.3.3 Calculation of results
The percentage of acidity (in HSO,) (X) is calculated as follows: (-V) · oX 0. 049 × 100
Wherein: V1--the volume of sodium hydroxide standard titration solution consumed by the sample, mLV.--the volume of sodium hydroxide standard titration solution consumed by the blank test, mL,--the concentration of sodium hydroxide standard titration solution, mol/L--the mass of the sample, g,
0.049--the mass of sulfuric acid equivalent to 1.00mL sodium hydroxide standard titration solution [c(Na0H)=1.000mol/L), expressed in grams.
5 Inspection rules
Carry out in accordance with the provisions of GB1604.
6 Marking, packaging, transportation, storage
6.1 Marking
Each package shall be marked in accordance with the relevant provisions of GB3796. 6.2 Packaging
Acephate technical should be packed in clean double-layer plastic bags, exhaust the air, seal the bag tightly, and then put it into cardboard boxes or calcium plastic boxes or pack it according to user requirements. Each small package should not exceed 1kg, and the net weight of each box should not exceed 25kg. The box should be accompanied by a product manual and a certificate of conformity, including: manufacturer name, product name, batch number, production date, net weight and proof that the product quality meets this standard. 6.3 Transportation
When shipping, this product should be handled with care according to the requirements for drug loading and unloading, and should not be thrown or dropped randomly. When the package is stored in the cargo yard or dock, it must be covered with bitter cloth.
6.4 Storage
When storing, this product should be protected from moisture, rain and sunlight, and maintained with good ventilation. It should not be mixed with food, seeds, and feed, and should avoid contact with skin and eyes, and prevent inhalation through the mouth and nose.
7 Safety measures for use
7.1 The concentration and dosage of the pesticide should be strictly in accordance with the instructions for use. 7.2 When the skin comes into contact with this product or the product is sprayed, the exposed parts of the body and the liquid should be washed with soap after contact. 2
