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

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

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

lowing order:-

1. This order may be cited as the Ready-mixed Gloss Enamel

Paint Order, 1980, and may be referred to as Order No. M 4 of 1980.

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 in the

Gazette.

1. This order applies to ready-mixed gloss enamel paints intend-

ed mainly for painting both interior and exterior surfaces.

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 Institution;

3.] .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, of 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 evaporati o n of the

solvent to the physico-chemica1 reactions of the binding medium,

or to 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 tueky undemeath. 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 further coat can be satisfactorily ap­

plied by brushing, if necessary, after flattening; this term is

a180 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;

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 ability of a coat of paint (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 obli­

terates 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 nat have

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

sent.

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

to in paragraph 15.3 shall not be more than 30 urn.

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

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

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

streakiness. joint lapping, flashing or any other undersirable film charac­

teristics.

1. When tested by the method referred to in paragraph 15.2 the

paint shall have a consistency of 110-190 Krebs-Stormer grams at a

shearing rate of 200 revolutians per minute when measured at a tem­

perature af 25°C ± 0.5°e.

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

method referred to in paragraph 15.3 shaB become surface dry in not

more than 8 hours at 25°e.

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 24 hours at 25°e.

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

referred to in paragraph 15.1 shall conform with the limits for the colour

in question la id down in the United Kingdom Ministry of Defence Spe­

cification DEF 1156A, published in 1964 by Rer Majesty's Stationery

Office in London.

Gloss.

1. When tested by the method referred to in paragraph 15.4 the

paint shall have a gloss of not less than 80%.

1. Seven days after applicatian using a mandrel 6.0 mm dia-

Bend Test.

meter, the paint at a wet film thickness of 50 urn shall not crack or lose

adhesion when tested in the manner referred to in paragraph 15.3.

Resistance to

1. The paint at a wet film thickness of 50 urn shall resist re-

abrasion.

moval after 80,000 oscillations of the abrasion machine under a load of

500 g when tested by the method described in paragraph 15.5.

1. The container shall be strong enough to withstand normal

Container.

usage and shall be adequately sealed to prevent leakage and contami·

nation of contents during handling and transportation.

1. Every container of ready mixed gloss enamel paint shall

bear a label showing in clear and easily readable print the following

information:--

14.1.1.

the colour name of the paint;

14.1.2.

the brand name or trade mark; or

14.1. 3.

name and address of the manufacturer shall be compulsory;

14.1.5.

the net contents in metric volume;

14.1.6. the warnings, or advice and directions as to use as

appropriate.

1. The opacity shall be determined by the method described in

the United Kingdom Ministry of Defence Specification DEF-I053. pub­

tished by Her Ma j esty's Stationery Office in London.

15.2. The consistency shall be determined by the method described

in A.S.T.M. Specification D 562-55.

15.3.

Surface drying time. hard drying time. bend test and fineness

of grind shall be determined by the method described in B.S. 3900.

15.4. The gloss shall be determined by the method

described in

A.S.T.M. Specification D 523-66T.

15.5. Apparatus

The testing shall be canied out on a "REL"

(London) Ltd using a nylon fi1led brush as supplied with the apparatus.

15.6. Procedure: The paint specimen sħall be prepared on a panel,

as described in B.S. 3900 and al10wed to dry hard for 7 days.

The panel shall then be fixed on the bed of the scrubbing

machine and covered with disti 11ed water. The brush shall be

lowered on to the panel and a 500g load applied to the brush. The
