The pH of an aqueous dispersion shall be 4.5 to 7.5

  Pourability

Maximum “residue”: 5%

  Spontaneity of dispersion

A minimum of 90% of the deltamethrin content found in suspension after 5 min in CIPAC Standard Water D at 30 ± 2°C

  Suspensibility

A minimum of 90% of the Deltamethrin content found in suspension after 30 min in CIPAC Standard Water D at 30 ± 2°C

  Wet sieve test

Maximum: 2% retained on a 75 μm test sieve.

 

Persistent foam

Maximum: 50 ml after 1 min
