penetration resistance การใช้

• Textile armor is tested for both penetration resistance by bullets and for the impact energy transmitted to the wearer.
• This history helps explain an important factor in Ballistics and Stab armor testing, backing stiffness affects armor penetration resistance.
• The turret was then mounted on a Type 97 Chi-Ha's hull and underwent penetration resistance testing.
• Vest specifications will typically include both penetration resistance requirements and limits on the amount of impact energy that is delivered to the body.
• When this occurs, soil in areas where horses are prevalent has a water penetration resistance over 15 times higher than that in areas without horses.
• In an effort to reduce the contamination of healthcare uniforms, ASTM International is developing standards to specifically address liquid penetration resistance, liquid repellency, bacterial decontamination, and antimicrobial properties of such uniforms.
• In practice the formal mechanical and structural factors related to snowpack instability are not directly observable outside of laboratories, thus the more easily observed properties of the snow layers ( e . g . penetration resistance, grain size, grain type, temperature ) are used as index measurements of the mechanical properties of the snow ( e . g . tensile strength, friction coefficients, shear strength, and ductile strength ).
