IS 10552: Scope & Key Specifications

Scope (Clause 3.1)

• Defines bucket sizes and capacities as per Table 1.
• Buckets are used for sewer cleaning with hinged flap bottoms.

Table 1: Dimensions of Buckets

Construction Highlights (Clause 4.3)

• Buckets have hinged flap bottoms that:
  • Open automatically when pulled into sewers.
  • Close automatically when pulled out.
• Each bucket has bails for attaching pulling ropes.

Rounding Off (Clause 0.4)

• Test results must be rounded per IS 2-1960.
• Number of significant figures in results = number in the standard.

Bucket Dimensions (Clause 3.1, Table 1)

Additional Notes

• Buckets must have hinged flap bottoms that open/close automatically during pulling (Clause 4.3).
• Bails for rope connection are mandatory.
• Rounding of test results per IS 2-1960.

This ensures compliance with IS 10552 for structural integrity and operational functionality.

IS 10552: Size and Capacity of Buckets

Key Specifications from Table 1 (Clause 3.1)

Construction (Clause 2.3)

• Minimum thickness of steel sheets/plates: 3 mm

Notes on Capacity

• Capacity correlates directly with bucket size (diameter and length).
• Buckets are designed for sewer cleaning using power-driven machines.

Rounding Off (IS 2-1960)

• Final values must be rounded off to the same significant figures as specified in the standard.

Summary

• Choose bucket size (B1 to B4) based on required diameter and length.
• Use steel plates ≥ 3 mm thick for fabrication.
• Follow IS 2-1960 for rounding test/calculation results.

IS 10552: Key Construction Specifications for Buckets

Bucket Dimensions (Table 1)

Construction Details (Clause 4.3)

• Hinged flap bottoms: Automatically open when pulled forward into sewers and close when pulled backward.
• Bails: Each bucket must have bails for attaching pulling ropes.
• Material Thickness: Steel sheets/plates thickness ≥ 3 mm (Clause 2.3).
• Material Quality: Use fusion welding quality structural steel, hot/cold rolled carbon steel sheets, or mild/medium tensile steel bars compliant with relevant IS specifications.

This ensures reliable operation and durability for sewer cleaning buckets per IS 10552.

IS 10552: Key Specifications & Marking for Buckets

Marking (Clause 5.1)

Each bucket must have a firmly attached plate showing:

• Manufacturer's name and trade-mark
• Designation (e.g., B1, B2, B3, B4)
• Year of manufacture

Dimensions of Buckets (Table 1, Clause 3.1)

Construction (Clause 4.3)

• Buckets have hinged flap bottoms that:
  • Open automatically when pulled into sewers
  • Close automatically when pulled out
• Equipped with bails for attaching pulling ropes

Rounding Off Results (Clause 0.4)

• Final test or calculation values must be rounded per IS 2-1960.
• Retain the same number of significant digits as specified in the standard.

This ensures consistent identification, sizing, and functional reliability of buckets used in sewer applications.

Testing and Quality Control - IS 10552 Key Points

Rounding off Test Results (Clause 0.4):

• Final test values must be rounded as per IS 2-1960.
• The number of significant digits in the rounded value should match the specified value's precision.

Bucket Specifications (Clause 3.1 & 4.3):

• Buckets must have hinged flap bottoms that open automatically when pulled into sewers and close when pulled out.
• Bails must be provided for rope connection.

Additional Notes:

• Material specifications refer to relevant IS codes for steel quality and reinforcement.
• Quality control should ensure compliance with dimensions and functional requirements (flap action, bail strength).
