2.6
SAMPLING AND TESTING
**************************************************************************
NOTE: Although provision is made for obtaining test
reports, importance of Government testing of each
batch of paint and reflective media is emphasized
where quantities of 200 or more liters (50 or more
gallons) are involved. For 200 (50) or less, the
factor of time and value of material versus cost of
testing may justify acceptance on the basis of test
reports furnished. In such cases acceptability will
be determined by persons within division or district
offices technically qualified and specifically
designated by division engineers. Requirements in
this paragraph for Contractor testing may be
modified to exempt materials that definitely will be
Government tested. If all batches will be
Government tested, requirements for Contractor
testing will be deleted.
**************************************************************************
Materials proposed for use shall be stored on the project site in sealed
and labeled containers, or segregated at source of supply, sufficiently in
advance of needs to allow 60 days for testing. Upon notification by the
Contractor that the material is at the site or source of supply, a sample
shall be taken by random selection from sealed containers by the Contractor
in the presence of a representative of the Contracting Officer. Samples
shall be clearly identified by designated name, specification number, batch
number, manufacturer's formulation number, project contract number,
intended use, and quantity involved. [Materials will be sampled and tested
by the Government. No material shall be used at the project prior to
receipt by the Contractor of written notice that the materials meet the
laboratory requirements. The cost of initial testing of samples from each
lot of materials will be borne by the Government. If the sample fails to
meet specification requirements, the material represented by the sample
shall be replaced and the new material will be tested. Cost of sampling
and testing the new material will be borne by the Contractor.] [Testing
shall be performed in an approved independent laboratory. If materials are
approved based on reports furnished by the Contractor, samples will be
retained by the Government for possible future testing should the material
appear defective during or after application.]

SURFACE PREPARATION
**************************************************************************
NOTE: Newly laid flexible and rigid pavements
require aging prior to painting in order to obtain
satisfactory paint performance. If practicable, all
new pavement surfaces should be at least 30 days old
before applying paint. When earlier application of
paint is necessary because of operations
requirements, the maximum period practicable should
be specified.
**************************************************************************
Surfaces to be marked shall be thoroughly cleaned before application of the
