The ASTM D6344 standard is intended to evaluate the ability of packaging to resist the force of concentrated impacts from outside sources, such as those encountered in various modes of transportation and handling. Damage to enclosures can impair the function of the equipment installed within (e. the con-trol systems of machines) or even, in the worst case, render it non-functional. Accordingly, in addition to IP protection (protection against dust, contact and water), enclosures must also have an adequate. 4. This test method is intended to determine the ability of packaging to protect. The first digit is our shield against these invaders: IP5X (Level 5): Dust-resistant—keeps out most particles but not completely dust-tight. Perfect for urban events or lightly dusty areas. IP6X (Level 6): Dust-tight—absolute protection against fine powders and particles. Essential for quarries or. Please review the permitted and restricted actions below: Standard Test Method for Concentrated Impacts to Transport Packages 1. 1 This test method covers procedures and equipment for testing complete filled transport packages for resistance against concentrated low-level impacts typical of those.
