CONDITION IN CONTAINER
1. SCOPE
1.1 Scope. This method covers procedures for determining changes in properties of paints and
related materials after packaging.
2. APPARATUS
2.1 Apparatus. No special apparatus required.
3. REAGENTS
3.1 Reagents. None required.
4. PROCEDURES
4.1 General. Before agitating the contents of the container in which the material was originally
packaged or transmitted for test, open the container by suitable means and determine the condition
of the material by one of the following applicable procedures against specified requirements.
4.1.1 Ready-mixed pigmented materials (paints, enamels, and so forth). Note whether skinning
has occurred and remove any continuous skin with a spatula by first carefully cutting the skin free
from the container. Lower a stiff spatula or paddle into the container and observe if the material is
abnormally thick or livered and to what extent settling or caking exists. Just stirring can usually
break up soft caking. When firm or hard caking is encountered, the supernatant liquid shall be
poured into a clean container and then added back in small amounts with continuous stirring until
the pigment has been reincorporated to form a homogeneous material suitable for use or until it is
determined that the pigment cannot be reincorporated by hand stirring. After the material has been
thoroughly stirred, examine for presence of gell bodies or undispersed conglomerates as it flows
from the spatula or paddle. Immediately after stirring examine the surface of the material for
floating pigments. Flow some of the material on a tin or glass panel; allow draining in a vertical
position and examining for loss of drying ability, color drift, seeding, and coarse particle. Check for
change in viscosity per applicable method such as ASTM D562.
4.1.2 Ready-for-use clear materials (varnishes, lacquers, oils, and so forth). Examine for skinning,
thickening, livering gelatinous masses, ingredient separation, and other specially defined
characteristics that may be objectionable for the specified material such as in 4.1.5. Examination shall
be made with the use of a spatula or paddle or by transferring the material to a clear glass container.
4.1.3 Pastes-in-oil and concentrates. Lower the spatula or paddle into the material and pass it
over the bottom of the container to determine the extent of caking. Add slowly with constant
stirring the specified thinning material and determine whether the paste or concentrate breaks up
readily to a smooth, homogeneous mixture of satisfactory brushing consistence.
