IS 7344:1974 is the Indian Standard (BIS) for bamboo tent poles. This standard specifies the requirements for materials, dimensions, manufacture, workmanship, finish, and testing of bamboo tent poles. It covers different types of poles such as ridge poles, wall poles, and corner poles used in various types of tents.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Straightness | Deviation from straightness shall not exceed 40 mm over a 3 m length. | Graded by deviation per meter; Grade A requires <10 mm/m, Grade B allows 10-25 mm/m. | ISO 19624:2018 |
| Preservative Treatment | Mandatory treatment with Copper-Chrome-Arsenic (CCA) or Acid-Cupric-Chromate (ACC) composition as per IS 401. | Recommends preservation based on use case and biological hazard class; does not mandate specific chemicals. | ISO 22156:2021 |
| Material Defects | Poles must be free from splits, cracks, rot, and live borer/termite attack. | Culms are graded (A, B, C) based on the size, location, and density of defects such as borer holes and cracks. | ISO 19624:2018 |
| Dimensional Specification | Prescribes specific lengths and top/butt diameters for different pole types (e.g., Type A: 5.5 m length, 75 mm butt dia, 50 mm top dia). | Does not prescribe product dimensions; provides methods for measuring diameter, wall thickness, and taper as inputs for grading and design. | ISO 19624:2018 |
| Seasoning Requirement | Shall be properly seasoned either by air or kiln drying. | Requires determination of moisture content; design strength values are modified based on 'dry' or 'wet' service conditions. | ISO 22156:2021 |
| Material Age | Shall be felled when mature (not less than 3 years old). | Maturity is a key factor in visual grading, typically requiring culms to be at least 3 years old. | ISO 19624:2018 |
