YAMAKA-AHI panel Impact test against solid ground. Start date: September 4th 2013( Heisei 25th )

[ Purpose ]
Durability confirmation in the construction of the AHI panel with adhesive glue and pin nails (0.6 mm in diameter).
[ Construction instructions ]
LGS65×40 303 mm pitch (picture 1)
Fasten the 12 mm foundation plywood to LGS with the screws provided (picture 2).
Glue the clear backed 5.5 mm AHI panel (picture 3)
and then hammer the pin nails (diameter: 0.6 mm) in 200 mm pitch to make gapped joints, and the installation is completed. (picture 4).

  1. 1. LGS65×40 303 mm pitch

  2. 2. An 12 mm area of LGS needs to be fasten together with screws

  3. 3. Glue the AHI panel together

  4. Side view of the testing material LGS + 12 mm

  5. Fasten the control panel with screws in 150 mm pitch.

  1. 4.Completed construction

  2. (the completed view of a test installation)

[ Testing procedure ]
Using a Japanese linden antibacterial panel once constructed, pay attention to the surface of the panel and to the form of the pin nails used for construction.
  1. 1. Hang a N0.7 basketball 60 cm (for high school or general use) from the panel and 90 cm distance from the floor with a 130 m string.
  2. 2. After pulling the ball up 220 cm from the floor, release the ball.
    The ball should make an impact on the panel at the same position and trajectory. The additional measurement number is bound by TANITA-PD635 (pedometer with vibration sensor).
  1. Hang a N0.7 basketball ( for high school or general use) from the panel.
  2. Hang 60cm from the panel and 90cm distance from the floor with a 130m string.
  3. After pulling the ball up 220cm from the floor, release the ball.
  4. TANITA-PD635(pedometer with vibration sensor).

YAMAKA-AHI panel Modification method

  • Before repair

  • After repair

repair instructions

  1. 1. Repair flaws and dents with “ALTECO GEL”".

  2. 2. Scrape the surface of the panel to make it flat and smooth.

  3. 3. Wipe off excessive “ALTECO GEL” from around a flaw or dent by a waste cloth.

  4. 4. Spray “ALTECO SPRAY PRIMER” on the part repaired with “ALTECO GEL” but let it harden completely before spraying. (It will harden instantly.)

  5. 5. Sand repaired parts to make it flat and smooth. (around #320→#600 grit sandpaper)

  6. 6. Match the finish of the repaired part to the other parts around it using an AF-AIR FLAT (12-938).

The antibacterial activity of YAMAKA-AHI panel board/The quality preservation

The antibacterial test. Inspected by: Japan Food Research Laboratories Issued date of the test report : 21st October 2011 Test specimen : The panel board with antibacterial activity against Japanese linden.

Testing method : JIS Z 2801: 2010 "The panel board with antibacterial treatment-Testing method for antibacterial activity, antibacterial effects"

Test result (Total viable bacterial count on 24 hours postinoculation)
Testing bacteria: Staphylococcus aurous Blank (The panel board with non antibacterial treatment) The panel board with antibacterial activity against Japanese linden.
Staphylococcus aurous 1.3×105 < 0.63 Non detection
Escherichia coli 1.0×106 < 0.63 Non detection

The total viable bacterial count of the panel board with antibacterial treatment demonstrate a decrease in comparison of antibacterial treatment panel with non treatment, less than 1/130000 at Staphylococcusus aurous, and less than 1/1000000 at Escherichia coli.

Right after inoculating Staphylococcus aurous

Maintenance of the quality

Physical property testing. Issued on 24th October 2011 By the inspection report of Yamagata prefecture Industrial Research Institute ( Test specimen: The panel board with antibacterial activity against Japanese linden.)
Test items The standard of the decorated panel board FW type with special treatment Test result
Category- 2 impregnation test Qualification : The length of each sides of unpeeled adhesive layers of test pieces must be over 50mm. No peelings on the adhesive layers
B test for repetition of cold and heat Qualification : The surface of testing pieces must not have any cracks or blisters, peelings, discolorations and lusterless remarkably. No cracks or blisters, peelings, discolorations and lusterless on the surface.
B test for water‐resistant The surface of testing pieces must not have any cracks or blisters, peelings, discolorations and lusterless remarkably. No cracks or blisters, peelings, discolorations and lusterless on the surface.
B test for contamination Must not have remain colors on the surface of testing pieces. No color remaining
B test for abrasion Must be over 50 at the abrasion level and 0.1 at the abrasion loss. the abrasion level: 59 / the abrasion loss: 0.052g
