component. Provide shipping documents, including either pre-paid shipping
or a shipper number that can be used by the Contracting Officer to arrange
pickup, addressed to the approved coating testing laboratory.
2.4
ABRASIVE SAMPLE COLLECTION AND SHIPPING KIT
Provide a kit that contains one suitable plastic bag or container for each
sample to be collected. Mark containers for the appropriate component.
Provide shipping documents, including either pre-paid shipping or a shipper
number that can be used by the Contracting Officer to arrange pickup,
addressed to the approved coating testing laboratory.
2.5
SOLUBLE SALTS TEST KITS
2.5.1
Test Kit for Measuring Chlorides on Steel Surfaces
Provide test kits called CHLOR*TEST, as manufactured by CHLOR*RID
International Inc. of Chandler, Arizona (www.chlor-rid.com) or equal.
An
"equal" test kit shall meet the following requirements:
a. Kit contains all materials,supplies, tools and instructions for
field testing and on-site quantitative evaluation;
b. Kit extract solution is acidic, factory pre-measured, pre-packaged,
and of uniform concentration;
c. Kit components and solutions are mercury free and environmentally
friendly;
d. Kit contains a factory sealed titration device;
e. Kit contains new materials and solutions for each test;
f. Test container (vessel, sleeve, cell. etc.) creates a sealed,
encapsulated environment during chloride ion extraction;
g. Test container is suitable for testing the following steel surfaces:
horizontal (up/down configuration), vertical, flat, curved, smooth,
pitted, and rough;
h. Kit uses test container, with resulting chloride ion extract
solution, as the titration container;
i. Chloride ion concentration is directly measured in micrograms per
square centimeter without using either conversion charts or tables.
2.6
ABRASIVE
The referenced abrasive specifications have maximum limits for soluble
salts contamination, however, this maximum level of contamination does not
guarantee that contamination will not be transferred to the steel surface
during abrasive blasting. Other factors such as on-site handling and
recycling can allow contamination of abrasive. Contractors are cautioned
to verify that the chosen abrasive, along with work and storage processes,
allow the final surface cleanliness requirements to be achieved.
Successful testing of chlorides in abrasive does not negate the final
acceptance testing of steel surfaces.
