  • Comparison with other manufacturers’ P5A security glass
  • Materials for the Steel Ball Drop Impact Test:
    P5A flat glass (7.7mm thick) of another manufacturer
    HERCULES III (7.5mm thick)
  • Test Method for Steel Ball Drop Impact Resistance
    The Steel Ball Drop Impact Test is to free-fall a solid steel ball (100mm in diameter, weighing 4.11Kgs) from the height of nine (9) meters above the surface of test material having measurements of 900mm x 1,100mm.
    The drop points are the apexes of a regular triangle having a side length of 130mm each. The steel ball free-drops on each apex of the triangle, and the dropping is repeated three (3) times, making the total number of the dropping nine (9) times.
    If the glass endures the foregoing drop impacts with no break-through at any apex, the glass is graded Class P5A in accordance with the Test Criteria of The Flat Glass Manufacturers Association of Japan.
  • Result of Steel Ball Drop Impact Test
    HERCULES III showed outstanding performance unparalleled with other manufacturers. HERCULES III was penetrated at the 17th drop, while the other glass penetrated at the 11th drop.

    • HERCULES V Blast-Resistant Glass (Anti-Terrorism)
    Overcome grenade attack by terrorists
  • HERCULES V is composed of two panes of float glass and a polycarbonate sheet sandwiched in between and firmly bonded together with polyurethane. Overall thickness is 19mm.
  • Recently, there is growing concern over the blast caused by terrorists, bomb attacks, accidental chemical reaction at production plants or research facilities, etc. Shock waves and flames generated by blast endanger human lives, properties and facilities.
  • HERCULES V provides "shield against blast"
    HERCULES V blocks shock waves generated by blast, and prevents damage from the shatters and fragments from the explosive.

  • HERCULES V features blast-resistant performance equivalent to that of the glass which has passed Bomb Blast - Hand Grenade HE High Explosive HG85 Test specified in Australian and New Zealand Standard AS/NZS 2343:1997.
  • The purpose of the blast-resistance test is to examine whether any penetration of fragments occurs by the specified detonation test which comprises two times of detonation of HG85 hand grenades; the 1st detonation on the ground and one meter distant from the glass, and thereafter the 2nd one at the height of 30cm above ground and also one meter distant from the glass.
  • Hercules V’s Anti-burglary Performance
    Hercules V substantially endures any of burglar’s break-in attempts either by torching typically with oxy-acetylene torch, impact tools such as hammers and axes, glass cutting with disc grinder.
    It takes eight (8) minutes to break Hercules V in combination of torching and impacts by experienced burglars. (In the case of the window having two crescent locks, it takes 16 minutes for breaking.) In Japan, burglars usually give up break-in attempts, if it is unsuccessful within five (5) minutes.
