No appreciable change after 300 hours of exposure. 
(Test method: Sunshine Carbon Arc testing based on JIS A1 & 15 testing methods)

2-(2) For Belbien EX series. 
No appreciable change after 5000 hours of exposure. 
(Test method: Sunshine Carbon Arc testing)

Taber Abrasion Resistance

More than 5000 cycles with a load of 1 kilogram on CS-17 abrading wheels. 
(More than 1000 cycles for Belbien FR and Belbien Suede series) 
(Testing method is based on a JAS testing standard)

Impact Resistance Under Low Temperature

No cracking observed with impact given to Belbien left under 0 degree Celsius for 24 hours. 
(Testing method is based on ASTM D-1790) 

Adherence Stability Under Higher Temperature

No appreciable defective adhesion after being left under 65 degrees Celsius for 1 month. 
(CI Kasei Co., Ltd.'s in-house testing method is adopted) 

Adherence Stability Under Higher Moisture

No appreciable defective adhesion after being left under 45 degrees Celsius with 95% of moisture for 1 month. 
(CI Kasei Co., Ltd.'s in-house testing method is adopted) 

Measurement stability

7-(1) Shrinkage of Belbien on peeling paper before installation
Width tolerance: +0 millimeter / -3.0 millimeters
7-(2) Shrinkage of Belbien after installation
Shrinkage tolerance: +0 millimeter / -0.3 millimeters
Test method:  Install Belbien (area or 120 x 120 millimeters) on an aluminum plate and cut notches with a range of 100 x 100 millimeters.  Measure the shrinkage between the notches after leaving the plate for 0.5 hours under the temperature of 100 degrees Celsius.
(CI Kasei Co., Ltd.'s in-house testing method is adopted)

Chemical & Solvent Resistance

Test procedure
(1) Drip the following substance onto Belbien's surface and cover the dripped area with a plate for 6 hours.
(2) After the above period, wash the surface with water and leave the surface for 24 hours.
(3) Observe the surface for appreciable change after the above (2) period
(Testing method is based on JIS K 6902)

Note: Belbien Suede series are less stable when applied with alkali and acid substances.

Staining Substance Resistance

Test procedure
(1) Apply the below substances onto the Belbien's surface and leave the surface touched with the substance for 24 hours.
(2) After the above (1) period, wipe the substances with neutral detergent and ethyl alcohol respectively
(Testing method is based on JIS K 6902)

+ indicates that the substance has been wiped off with neutral detergent.
O indicates that the substance has been wiped off with ethyl alcohol.
- indicates that the substance remains as a stain.

Adherence Against Peeling

Test procedure
(1) Adhere Belbien onto the following substrates and leave for 3 days.
(2) After the above (1) period, peel the Belbien adhered with the angle of 180 degrees.
(3) When Belbien is peeled off the surface, measure the peeling weight applied per peeling width of 25 millimeters.

Burning Resistance

The below ratings reflect the result arrived at by the test conducted by UL, Inc. 

UL 723 and ASTM E-84 are tests results that utilized exactly the same test methods.  In other words, when you have a certificate from one of these testing agencies, then it will meet the requirements for the following agencies for flame and smoke development:

UL-723
ASTM E-84
NFPA 255 (National Fire Protection Association)
UBC 8-1 (Uniform Building Code)
BBC E-84 (Boca Building Code)
SBC E-84 (Standard Building Code)
