another. Today the market is much better prepared to
use colorimetry in day-to-day business. Brazil is one
of the most developed countries in Latin America, but
it still has a long way to go to get to the level of kno-
wledge of using colorimetry in paints that is found
in first-world countries,” says Ricardo Gargalaca,
director at Coralis.
With colorimetry, the whole subjectivity of human
vision is turned into a measurable attribute, with co-
lor behavior figures and numeric tolerance ranges on
both the dimensional
and behavioral levels.
It is important to use a
tool which, combined
with human skill, can
accurately solve any
doubts about the beha-
vior of a given product
as regards color (tone,
undertone, metame-
rism, hiding power).
The benefits provided
by this technology in-
clude fast color analy-
ses, numerous illumi-
nants, modern com-
putation methods for
viewing color behavior
(quality control), and,
of course, formulation
and correction, shorte-
ning both making and
correction times for the
colors required, which
altogether makes colo-
rimetry an important
tool for colorists and
other professionals of
the industry.
Groupack - Into the standard
Established 13 years ago to serve the nation’s che-
mical industry, Groupack opted to add security to
its packaging materials from the outset. “We were
one of the first bucket manufacturers in the natio-
nal territory to get an ISO 9000 certification, and
the first manufacturer in Brazil to certify and put
on the market a plastic bucket for general purpo-
ses, rather than a specific one for just one custo-
mer, meeting the requirements of Resolution 420 of
the ANTT (National Inland Transportation Agency)
for carriage of hazardous materials,” stresses
Groupack’s director Pablo Horácio Conte.
He also says that, because it is a new standard, ANTT
420 is still in the process of being assimilated by the
chemical industry, and many chemical companies are
just starting to review the kinds of packaging that
they are provided with. “But a standard has been in
existence since 2003 which is hardly ever mentioned,
ABNT NBR 14952:2003. It was specifically designed
by the Brazilian Association for Technical Standar-
dization for injected plastic buckets for industrial
purposes, and takes
a very comprehensive
approach to this kind of
packaging. This standard
puts everything to the
test, from the loop to fall
and stack resistance,”
says Conte.
Since it is a responsibility
standard, rather than
a compulsory one, such
as ANTT 420, the NBR
14952 standard is barely
known to customers.
“The problem is it doesn’t
distinguish the buckets
used in the food industry
from those used in the
chemical industry. That
detail, which is seemin-
gly irrelevant, actually
causes a lot of nuisance
in the marketplace, as
we all know that olive
bucket that leaking in
the trunk of our cars is
not so disturbing as a
leaking paint bucket,”
says Conte.
In Conte’s opinion, there should be different requi-
rements for food and chemical packaging materials,
as price is more important than safety in the first
case, but it is the exact opposite in the second one.
“In an attempt to minimize these divergent inte-
rests, Groupack provides both the food and chemical
industries, whose main concern is to ensure the in-
tegrity of their products, with a range of 1 to 20-li-
ter buckets that are manufactured in accordance
with the requirements of the NBR 14952 standard.
These buckets are specifically designed and impro-
ved for chlorine, adhesives, sealants and gelcoats,”
Conte concludes.
