Red Lead Priming Paint Order, 1982

(Ordni Nru. M 12 ta' 1·1982)

IN exercise of the powers conferred by section 3 of the Quality

Control (lmports, Exports and Local Goods) Act, 1971, and in accord-

ance with that section, the Malta Board of Standards has made the

following order:-

1. This order may be cited as the Red Lead Priming Paint

Order, 1982, and may be referred to as Order No. M 12 of 1982.

1.2. This order shall become operative on a date after the lapse of

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

Representatives which date shall be notified by the Board by notice in

the Gazette.

1.

This order applies to ready-mixed red lead priming paint.

In this order -

1.

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 Institute;

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 reaction of the binding medium, or to a

combination of these causes. Various successive stages in the drying

of the 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 com-

monly known as "sand-dry";

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

stage that, if desired, a second coat can be satisfactorily applied

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

to describe certain degrees of film hardness when tested by

specific 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.

1. The paint in freshly opened containers shall, on receipt, be COlldition in

free from skins, shall show no livering, lnstability, or caking, and shall container.

resin and not more than 22 % solvent. The pigment shall consist of not

less than 55 % red lead expressed as Pb. s 0 1 •

1. vVhen tested by the method referred to in paragraph 14.1 the Consistency.

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

ture of 25 ° ± O.5°C.

1. The paint shall brush easily and the resultant film shall be BTUshing

uniform and free from roughness and grit. It shall show no running or appearance.

sagging tendencies and not more than s11ght brush-marks.

ti an of resin content. Dry centrifuge tube in an oven at 105°-
