1980.

1.2. This order shall become operative on a da te after the lapse

of 20 days from the day on which it is la id on the Table of the House

paints intended mainly for painting both interior and exterior surfaces

for domestic use.

In this order -

3.1.1. "A.S.T.M." means the American Society for Testing

and Materials;

3.1.2. "B.S." refers to the British Standard of the British

Standards Institution;

3.1.3. "consistency" means the apparent viscosity of a paint

when shearing forces of varying degrees are applied to it in various

ways, such as when it is stirred in the can, poured from the vessel

to the other, brushed, or otherwise spread over a surface;

3.1.4. "drying" means the process of change of a coat of

paint from a liquid to the solid state, due to the evaporation of

the solvent to the physico-chemical reactions of the binding

medium, or to a combination of these causes. Various successive

stages in the drying of paint are distinguished by the following

qualifying terms, with corresponding times;

3.1.4.1. "surface dry" - when the paint is dry on the

surface but is soft and tucky underneath, which is also

commonly known as "sand-dry";

3.1.4.2. "hard dry" - when drying has reached such a

stage that, if desired, a further coat can be satisfactori1y applied

by brushing, if necessary, after flattening; this term is also used

to describe certain degrees of film hardness when tested by spe­

cific methods;

3.1.5. "drying time" means the time which elapses between

the application of a coat of paint and the attainment of a specified

dry state;

3.1.6. "enamel" means paints which, when dried,

have a

characteristic smoothness and gloss;

3.1.7. "gloss" means the degrees to which a painted surface

possesses the property of reflecting light in a mirror-like manner;

3.1.8. "opacity" means -

3.1.8.1. qualitatively, the abi1ity of a coat

(or a paint

system) to obliterate the colour of the surface to which it is

applied;

3.1.8.2. quantitatively, the extent to which a paint

obliterates the colour of an underlying surface of a different

colour when a film of it is applied by some standard method.

1. The paint shall be free from surface skin, it shall not have

jellied, its settling shall be soft and there shall be no foreign matter

present.

1. The fineness of grind, when measured by the method referred

to in paragraph 15.3 shall not be more than 60 urn.

1. The paint shall on application flow and spread well and shall

show no excessive pulI under the brush. The paint film shall be free

from sags and runs, shall show no brushmarks, flotation of the pigment,

streakiness, joint lapping, flashing or any other undesirable film

characteristics.

1. When tested by the method referred to in paragraph 15.1

the paint shall have a consistency of 180 to 280 Krebs-Stormer grams

at a shearing rate of 200 revolutions per minute when measured at a

temperature of 25°C ± 0.5°C.

1. The paint shall be in such a condition that when tested by

the method referred to in paragraph 15.3 shall become surface dry in

not more than 5 hours at 25°C.

8.2. The paint shall be in such a condition that when tested by

the method referred to in paragraph 15.3 shall become hard dry in not

more than 16 hours at 25°C.

1. The opacity of the film, prepared and tested by the method

referred to in paragraph 15.1 shall be not less than 80% .

1. Meta teżaminaha bil-metodu msemmi fil-paragrafu 15.4 iż-

żebgħa jrid ikollha leqqa ta mhux iktar minn 20%.

1. Sebat ijiem wara li tapplikaha, bI-użu ta' mandrel ta' dija-

metru ta' 6.0 mm iż-żebgħa b'passata frisk a tal-ħxuna ta' 50 urn ma

għandhiex tinqasam jew tinqala' meta teżaminaha kif deskritt fil-para­
