The term "rugged" refers to three key protections: waterproof, shockproof, and dustproof. Ruggedness standards are based on national technical specifications, tailored to market and customer needs, and classified into three tiers:

Ruggedness Classification:

1. Basic Rugged (IP56)

   • Dustproof: Level 5 (limited ingress, no harmful deposits)

   • Waterproof: Level 6 (powerful water jets)

   • Drop Resistance: 1.5 meters

   • Vibration: Standard industrial testing

2. Intermediate Rugged (IP57)

   • Dustproof: Level 5

   • Waterproof: Level 7 (immersion up to 1m/30min)

   • Drop Resistance: 3 meters

   • Vibration: Standard

3. Professional Rugged (IP68)

   • Dustproof: Level 6 (total dust ingress protection)

   • Waterproof: Level 8 (continuous immersion beyond 1m)

   • Drop Resistance: 5 meters

   • Vibration: Standard

What is a Rugged Phone?

By definition, a rugged phone is a waterproof, shockproof, and dustproof mobile device. These phones primarily serve:

• Professional outdoor enthusiasts

• Military personnel

Types of Rugged Phones:

1. Outdoor/Military-Grade Rugged Phones

   • Higher protection standards (IP68+): Survives submersion, desert conditions, and heavy impacts

   • Robust design: Thickness typically 16-25mm, functional but less aesthetically focused

   • Primary users: Adventurers, hikers, soldiers

   • Main manufacturers: European/American companies

2. Fashion Rugged Phones

   • Moderate protection (focus on water resistance, e.g., IP67)

   • Sleek design: Thinner (<15mm), smart features (Android/iOS)

   • Primary users: Style-conscious youth

   • Main manufacturers: Japanese/Korean brands

The Runbo Standard for True Ruggedness

As a leader in high-quality outdoor rugged phones, Runbo has established an industry-defining benchmark by:

• Combining IPXX sealing ratings with advanced shock/drop resistance

• Setting strict criteria for pressure/impact resilience

• Requiring full compliance to earn the "True Rugged Phone" certification
