METHOD OF TEST:  Coatings were subjected to the above chemicals according to the specification procedure as outlined in ASTM C 744 and S-C-621b and FR tests. 

FACING ADHESION TEST
PERFORMANCE:  No failure of adhesion of the facing material to the concrete surfaces.
METHOD OF TEST:  Weighed specimens of Spectra-Glaze® II coating immersed in distilled water at 70° F for three (3) consecutive 8-hour periods.  Specimens were dried superficially with towel to remove surface moisture only and weighed after each 8 hour exposure to determine rate of absorption. 

ABRASION RESISTANCE
PERFORMANCE:  Minimum standard allowed shall not exceed 130 wear factor.  Average actual result equals 43.3 per Taber Wear Factor.  Lower readings indicate better abrasion resistance.
METHOD OF TEST:  Specimens of Spectra-Glaze® II coatings, 4 inches square and 1/8 inch in thickness tested for resistance to abrasion using Taber Abraser equipped with CS-17 calibrase wheels with 1,000 gram loading, for 500 wear cycles.

FIRE RATING & SURFACE BURNING
PERFORMANCE:  Up to 4 hours fire rating.  Flame spread less than 25, fuel contribution 0, smoke density less than 50.
METHOD OF TEST:  Tested in accordance with ASTM E 119 and ASTM E 84.

ENVIRONMENTAL ELEMENTS RESISTANCE
PERFORMANCE:  On comparing test specimens with duplicate unexposed specimens, no significant change in color, gloss or texture detected after 500 hrs. of accelerated weatherometer.
METHOD OF TEST:  Coated specimens with duplicate unexposed specimens, no significant change in color, gloss or texture detected after 500 hrs. of accelerated weatherometere.
METHOD OF TEST:  Coated specimens 3 inch by 6 inch, exposed to 500 hours of accelerated weathering consisting of repeated cycles of 102 minutes of ultraviolet radiation followed by 18 minutes of radiation plus water spray.

CLEANSIBILITY & RESISTANCE TO SOILING
PERFORMANCE:  (A):  Stain removed in accordance with applicable standards as outlined in ASTM C 744 and Fed. Specs. SS-C-621 b, Form B. Meets or exceeds standards for staining as outlined in appropriate specifications.
METHODS OF TEST:  Stain consisting of 0.5 gram of oil-soluble range dye (C.1 solvent orange 7, C.1, 12140), 1.0 gram of lanolin, and 5.0 grams of S.A.E.  10 lubricating oil applied to area of coating approximately ½ inch in diameter for period of 4 days.  Test specimen then cleaned by placing in Gardner M-105-A washabilly machine, using industrial grade “Lestoil” as cleansing agent.  After 80 cycles the surface was examined. 

CLEANSIBILITY AND RESISTANCE TO SOILING
PERFORMANCE:  (B): 
Stain  Cycles Effect
Lead Pencil 10 None
Black Crayon   60 None
Magic Marker  150  None
Lanolin & Carbon Paper 60  None


METHOD OF TEST:  Each of the above staining media was applied to test specimens:  lead pencil #2 black crayon; magic marker (Speedry Products, Inc); lanolin and carbon paper (Fed. Spec. TT-P-29).  Specimens were cleaned using Gardner M-105-A washability machine, with “Lestoil” commercial grade and paint thinner (Magic Marker stain).

ACID RAIN RESISTANCE
PERFORMANCE:  No change to surface characteristics after 20 year simulated explosure.
METHOD OF TEST:  Glazed surface exposed to acid rain (70% sulfuric/30% nitric) for a period that simulated 20 consecutive years in environmental conditions of New York City. 

GAMMA RADIANCE RESISTANCE
PERFORMANCE:  1. No change when exposed to normal doses.  2.  Slight darkening in accident conditions.
METHOD OF TEST: (Normal Dose) Equivalent to 40 years exposure in normal use in nuclear power plant in vicinity of nuclear reactor.  (Accident) Equivalent to 6 months exposure during accident conditions defined as a loss of coolant accident (Loca).  Test conducted by Radiation Technology, Inc. 

FREEZE/THAW DURABILITY
PERFORMANCE:  No separation, spalling, cracking or disintegration of facing. 
METHOD OF TEST:  Glazed face tested at a level of 50 cycles according to ASTM C67-68 Para. 8 and Thermal Shock Test B 100-JL, 24P.

LIGHT REFLECTANCE VALUES
PERFORMANCE:  Light reflectance values for all standard Spectra-Glaze® block colors are available from your local manufacturer or The Burns & Russell Co.
METHOD OF TEST:  Light reflectance values developed using standard light reflectance meter.
