BATH COMPARISON TESTS: Overview

Test:	EC	GC	ACRYLIC Cultured Marble
Front Impact- chip or mark (1)	1-2"	12-24"	>24"
Reverse Impact (1)	<=36" dent	<=36" cracks	>36"
Hot Water - Color Change (2)	delta L = -2.4 delta a = 0.2 delta b = 4.99	delta L = -1.0 delta a = -0.4 delta b = 0.76	delta L = -2.4 delta a = -1.0 delta b = 10.2
Hot Water Resistance - damage? (3)	OK	OK	OK
Heat Loss (4)	Low	Low	Med. Low
Rust Stain Test (5)	?	OK	?

Notes:

(1) 2" diameter stell ball drop: Damage Height, inches, on either Front (top) or Reverse (bottom) surface. Similar to ANSI Z124.1 test (1.5" ball).

(2) ANSI Z124.1 - 100 hours contact with 150F water. Color change in L, a, b colorimeter units. Run again. Request to set up rig was made.

(3) Hot Water Resistance, ANSI Z124.1 - 500 cycles. See sample. The acrylic and cultured marble showed slight blistering. After sitting on the shelf, the CM part shows many spots of blistering or delamination. Need to run again.

(4) Temperature drop versus time for hot water held in bat. Demonstrate thermal differences.

(5) Rust stain test. Ran acrylic vs. Centrex in Fite Rd. ditch before. Run again with ES, GC, CM.
