    D[Hand Brake] --> E[Hold Vehicle on 1 in 4 Gradient]

This ensures safety in both motion and stationary conditions as per IS 955.

IS 955 Stability Requirements Summary

• Stability Criterion (Clause 4.11):
  The appliance must not overturn when tilted up to 25° from the horizontal under fully equipped and loaded conditions (excluding crew).

• Interpretation:
  The overturning angle θ ≥ 25° ensures safe operation on inclined surfaces.

Key Formula for Stability Angle

The overturning angle θ can be approximated by:

[ \tan \theta = \frac{B}{2h} ]

Where:

• ( B ) = Track width (distance between wheels)
• ( h ) = Height of the center of gravity (CG) from the ground

To satisfy IS 955:

[ \theta \geq 25^\circ \implies \tan 25^\circ \leq \frac{B}{2h} ]

Or,

[ \frac{B}{2h} \geq 0.466 ]

Design Implications

• Increase track width (B) or lower CG height (h) to improve stability.
• Ensure fully loaded conditions are considered for CG location.
• Stability testing involves tilting the vehicle to 25° sideways without overturning.

graph LR
A[Ground] --> B[Vehicle Base Width (B)]
B --> C[Center of Gravity Height (h)]
C --> D[Overturning Angle (θ)]

Summary:
Design the appliance so that:

[ \boxed{ \frac{B}{2h} \geq \tan 25^\circ \approx 0.466 } ]

to meet IS 955 stability clause 4.11.

IS 955: Workmanship and Finish - Key Points

• Clause 5.1: All parts of the appliance must exhibit good workmanship — smooth, uniform, and free from defects such as cracks, sharp edges, or burrs.

• Clause 3.2:

  • Water-contact parts: Must be made from corrosion-resisting materials (e.g., stainless steel, brass).
  • Exposed metal parts: Either corrosion-resisting or adequately treated (galvanized, painted, or coated) to prevent corrosion.

• Stability (Clause 4.11): The appliance must remain stable up to a tilt angle of 25° under full load (excluding crew).
