ASTM Proposes New Metal
Corrosion Standard to
Test Potential Coatings for
Sewer Environments
The headspace in domestic wastewater
collection and treatment systems is a severe environment that can impact even
high performance protective coatings.
A proposed new ASTM International
standard covers an apparatus and set of
procedures that are used to create and
maintain a simulated sewer headspace
environment to be used to test potential
coatings.
ASTM WK33537, Practice for
Operating the Severe Wastewater
Analysis Testing Apparatus, is being developed by Subcommittee G01.05 on
Laboratory Corrosion Tests, part of
ASTM International Committee G01 on
Corrosion of Metals.
The apparatus described in ASTM
WK33537 is designed to simulate the
pertinent attributes of a typical domestic
sewer wastewater headspace found in a
sewer. Testing is done within two phases
in the chamber: a liquid phase contain-
ing a prescribed acid and saline solution;
and a vapor phase consisting of air, hu-
midity and concentrated sewer gas, which
is composed of hydrogen sulfide, carbon
dioxide and methane gases.
The temperature of the test chamber is
elevated to create accelerated conditions
and reaction rates.
While certain chemical and physical
properties of coating systems can be determined in laboratories, testing with the
apparatus and procedures described in
ASTM WK33537 will provide a more accurate simulation of the environment of
an actual sewer system.
Randolph Products Receives
New QPD Listing
Randolph Products Company has received a new QPD listing for its MIL-
PRF-22750G Type 3 DTM epoxy to add
to their list of Qualified Products.
This new Qualified Products listed
spec joins Randolph’s other 2013 QPD
approved product MIL-PRF-24667C
Comp G Ty I and II non-skid which was
approved in January after testing on the
U.S.S. George H.W. Bush (CVN- 77) aircraft carrier.
The new QPD MIL-PRF-22750G
Type 3 epoxy DTM Mil-Spec coating
eliminates the need for primer on Army
ground equipment and is used for both
interior and exterior applications.
CeralUSA Achieves
AS9100C Compliance
CeralUSA LLC, manufacturer of environ-
mentally friendly coatings for the aero-
space, power generation and oil and gas
industries, recently announced that its
Quality Management System was audited
and found to be in full compliance with
the widely adopted and standardized qual-
ity management system for the aerospace
industry, AS9100C. The Moore Norman
Technology Center’s certified AS9100C au-
ditors deemed CeralUSA’s processes and in-
ternal documentation to be fully compliant.
Foreign Paint Firms
Cornering Vietnam
Manufacturers
Foreign-invested paint companies in
Vietnam are putting pressure on local
manufacturers.
The Vietnam Paint and Ink Association
said the country has an annual total output of 250 million liters of paint, including 180 million liters of decorative paint.
Chalermsak Pimolsri, marketing director of the foreign-invested Four Oranges
Paint Company, said the average consumption was 1.5 liters of paint per head
per year in Vietnam, much lower than the
four liters a year in Thailand and seven
liters in developed countries.
Foreign-invested paint makers already
hold 65 percent of the local market and
have advantages with trade marks, finance
and diversification of products, he said.
Another foreign-invested paint firm,
Jotun Vietnam Co. Ltd., has expanded its
factory and increase capacity to 25 million litres of paint per year.
Director of AkzoNobel Paints Vietnam,
David Teng, said the company had invested
€ 13 million ($17.3 million) to develop a factory in southern Binh Duong Province.
The association said Vietnam has approximately 600 paint companies, including 30 foreign-invested firms holding
the lion’s share of the market. Local paint
