Council Directive of 15 July 1991 concerning the placing of plant protection products on the market (91/414/EEC) (repealed)

[F1 2.8. Technical characteristics of the plant protection product U.K.

The technical characteristics of the preparation must be determined to permit a decision to be made as to its acceptability.

2.8.1. Wettability U.K.

The wettability of solid preparations which are diluted for use (e.g. wettable powders, water soluble powders, water soluble granules and water dispersible granules), must be determined and reported according to CIPAC Method MT 53.3.

2.8.2. Persistent foaming U.K.

The persistence of foaming of preparations to be diluted with water, must be determined and reported according to CIPAC Method MT 47.

2.8.3. Suspensibility and suspension stability U.K.

• The suspensibility of water dispersible products (e.g. wettable powders, water dispersible granules, suspension concentrates) must be determined and reported according to CIPAC Method MT 15, MT 161 or MT 168 as appropriate.

• The spontaneity of dispersion of water dispersible products (e.g. suspension concentrates and water dispersible granules) must be determined and reported according to CIPAC Methods MT 160 or MT 174 as appropriate.

2.8.4. Dilution stability U.K.

The dilution stability of water soluble products must be determined and reported according to CIPAC Method MT 41.

2.8.5. Dry sieve test and wet sieve test U.K.

In order to ensure that dustable powders have a suitable particle size distribution for ease of application, a dry sieve test must be conducted and reported according to CIPAC Method MT 59.1.

In the case of water dispersible products, a wet sieve test must be conducted and reported according to CIPAC Method MT 59.3 or MT 167 as appropriate.

2.8.6. Particle size distribution (dustable and wettable powders, granules), content of dust/fines (granules), attrition and friability (granules) U.K.

2.8.6.1. The size distribution of particles in the case of powders, must be determined and reported according to OECD Method 110. U.K.

The nominal size range of granules for direct application must be determined and reported in accordance with CIPAC MT 58.3, for water dispersible granules in accordance with CIPAC MT 170.

2.8.6.2. The dust content of granular preparations, must be determined and reported according CIPAC Method MT 171. If relevant for operator exposure the particle size of dust must be determined and reported according to OECD Method 110. U.K.

2.8.6.3. The friability and attrition characteristics of granules, must be determined and reported once internationally agreed methods are available. Where already data are available they must be reported together with the method used. U.K.

2.8.7. Emulsifiability, Re-emulsifiability, emulsion stability U.K.

2.8.7.1. The emulsifiability, emulsion stability and re-emul-sifiability of preparations which form emulsions, must be determined and reported according to CIPAC Methods MT 36 or MT 173 as appropriate. U.K.

2.8.7.2. The stability of dilute emulsions and of preparations which are emulsions, must be determined and reported according to CIPAC Method MT 20 or MT 173. U.K.

2.8.8. Flowability, pourability (rinsability) and dustability U.K.

2.8.8.1. The flowability of granular preparations must be determined and reported according to CIPAC Mehtod MT 172. U.K.

2.8.8.2. The pourability (including rinsed residue) of suspensions (e.g. suspension concentrates, suspo-emulsions), must be determined and reported according to CIPAC Method MT 148. U.K.

2.8.8.3. The dustability of dustable powders following accelerated storage according 2.7.1 must be determined and reported according to CIPAC Method MT 34 or another suitable method.] U.K.
