Domestic sanitary insecticidal - Aerosols
1 Scope
This Standard specifies the terms and definitions, requirements, test methods,
inspection rules and marking, packaging, transportation, storage, and
instructions for use of domestic sanitary aerosols insecticide.
This Standard applies to products that are formulated from active constituents
and suitable solvents and auxiliaries. It uses propellants as an impetus to fill in
the pressure-resistant container; the contents are ejected in a predetermined
form to kill injurious insects.
2 Normative references
The following documents are indispensable for the application of this document.
For dated references, only the dated version applies to this document. For
undated references, the latest edition (including all amendments) applies to this
document.
GB/T 601, Chemical reagent - Preparations of reference titration solutions
GB/T 1600-2001, Testing method of water in pesticides
GB/T 1601, Determination method of pH value for pesticides
GB/T 2828.1-2012, Sampling procedures for inspection by attributes - Part
1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot
inspection
GB/T 2829-2002, Sampling procedures and tables for periodic inspection by
attributes (apply to inspection of process stability)
GB 24330, General security technical specification for domestic sanitary
insecticide
3 Terms and definitions
The following terms and definitions are applicable to this document.
3.1 Aerosols insecticide
5 Test method
5.1 General
Requirements for use of active constituents, toxicology, active constituent
content and allowable fluctuation range, pesticide effect, heat storage stability,
aerosols insecticide methanol content, aerosols insecticide internal pressure,
aerosols insecticide net content shall be tested according to the provisions of
GB 24330.
5.2 Appearance and senses
5.2.1 Appearance is inspected visually.
5.2.2 Senses are judged from smell.
5.3 Spray rate
5.3.1 Instruments
5.3.1.1 Constant temperature water bath: temperature control accuracy of
±2 °C.
5.3.1.2 Balance: the division value is not less than 0.01 g.
5.3.2 Test steps
Take the sample in a water bath at (25 ± 2) °C; soak the water to four-fifths of
the sample height; keep the temperature constant for 30 min; remove the
sample and dry it; weigh the mass m1 (accurate to 0.1 g); shake the sample;
spray the contents according to the spray direction that is marked by the sample
until the contents cannot be sprayed; then, weigh the mass m2 (accurate to 0.1
g); open the sample and remove the remaining liquid; then, weigh the tare m3
(accurate to 0.1 g).
The spray rate is calculated according to Formula (1):
Where:
rs -- spray rate;
m1 -- the mass of the sample before spraying, in grams (g);
m2 -- the mass of the sample after spraying, in grams (g);
V1 -- the volume of potassium hydroxide standard titration solution that is
consumed by the titration sample solution, in milliliters (mL);
m4 -- sample mass before sampling, in grams (g);
m5 -- sample mass after sampling, in grams (g);
0.0365 -- the mass of hydrochloric acid (HCl) that is equivalent to the
concentration of 1.00 mL of potassium hydroxide standard titration
solution [c (KOH) = 1.00 mol/L].
5.4.2 pH measurement (water-based, alcohol-based products)
Shake the sample; use a nozzle with a catheter to slowly spray the appropriate
amount of insecticide into the test tube; put it in a 55 °C water bath; after the
propellant is slowly exhausted (until there are no obvious bubbles), perform the
test according to the method of GB/T 1601.
5.5 Moisture
Take the sample after pretreatment, according to the Karl Fischer method in
GB/T 1600-2001 (it is allowed to use a trace moisture analyzer of the same
accuracy).
Note: "sample after pretreatment" is the sample that has been pretreated during
the measurement of the content of the active constituent.
6 Inspection rules
6.1 Inspection classification
Inspection is divided into delivery inspection and type inspection.
6.2 Delivery inspection
The product can only be delivered after being inspected by the quality
inspection department of the manufacturer in accordance with this Standard; it
is accompanied by instructions for use and inspection mark. The delivery
inspection adopts the normal inspection single sampling plan of GB/T 2828.1-
2012 special inspection level S-2. The inspection items, requirements, test
methods and acceptance quality limit AQL value are shown in Table 1.
