||Coil Coatings Conversion
NCCA Converts to Use of ASTM Standards; Issues Compilation
by David A. Cocuzzi
The National Coil Coating Association has decided to convert from their own test methods, developed
over the past 30 years, to ASTM standards. Additionally, a special
compilation of these standards has been organized and published
as a joint effort between ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications; Subcommittee
D01.53 on Coil Coated Metals; and the NCCA Technology Committee.
This book is a collection of 100 ASTM test methods relevant to
the coil coating industry. Its publication also represents a significant
departure for the NCCA from its historic practice of authoring
and publishing its own test methods.
By cooperating with ASTM to create newand update existingmethods,
NCCA has been able to take advantage of the work done by the 32,000
members of ASTM. NCCA recognizes the international standing that
ASTM enjoys in the area of standards writing, as well as the widespread
acceptance and use of these standards in specifications worldwide.
ASTM, in turn, understands the need for major industries to be
represented in the form of subcommittees, such as D01.53.
Every effort has been made to make this an exhaustive guide to
the standards, test methods, and common practices employed by
the North American coil coatings industry. Within this book can
be found test methods involving the measurement of liquid coating
parameters (e.g., weight per gallon, viscosity, and rheology),
cured-film parameters (coating flexibility, hardness, etc.), appearance
measurements (color, gloss, metamerism, etc.), corrosion and durability
properties, as well as a number of methods associated with the
measurement of solar reflectance. Standard D 3794, Guide for Testing Coil Coatings, even indicates, at a glance,
all of the ASTM test methods that are relevant to the coil coating
industry, accompanied by a descriptive narrative, indicating the
need forand value ofeach test method.
The NCCA will be the sole distributor of this compilation. The
NCCA Technology Committee intends to monitor the trends in the
industry and update this book at least every five years. Standards
that become unnecessary with time will be removed; more importantly,
as new, pertinent standards are published, these will be included
in each update. Managing standards activity, which is of critical
importance at every step of the coil industry supply chain, is
the greatest strength of this NCCA-ASTM partnership.
Given the broad range of coatings-related methods covered, the
special compilation will be of interest to anyone in the field
of decorative and protective coatings, not just specialists in
coil coatings. //
