☘️HPBC guidelines for Calibration
-Pie load test ပြုလုပ်ရာတွင် system တစ်ခုလုံးအတွက် calibration ပြုလုပ်ထားလျင် Load cell မထည့်ရန် ခွင့်ပြုသည်။
-Load test ပြုလုပ်ရာတွင် အသုံးပြုမည့် Load cell, Hydraulic Jack, Pressure Gauge & Pressure Transducer, Dial Gauge နှင့် Linear Variation Displacement Transducer (LVDT) တို့၏ Calibration ပြုလုပ်ထားခြင်း သက်တမ်းသည် (၆)လအတွင်း ရှိရမည် ဖြစ်သည်။

Bored Pile Load Test (Equipment & Tools)
The equipment and tools used for conducting Static Load Tests and Dynamic Load Tests are as follows.
-Hydraulic Jack for vertical and lateral load apply
-Load cell (optional) for direct load measurements
-Pressure Gauge for measuring jack pressure (indirect load)
-Dial Gauges for measuring displacement
-LVDT (linear variation displacement transducer) for precise settlement/displacement readings
-Strain Gauges for measuring stress/force in pile
-Accelerometers for measuring pile acceleration (velocity)
-Steel reaction frame / Kentledge to transfer jack load to pile
-Hammer to apply impact load
-PDA (pile driving analyzer) measures force and velocity during hammer impact
The above tools and equipment must be calibrated at certified calibration laboratories.
HPBC guidelines for Calibration
-When the entire system is calibrated for pile load testing, the use of a load cell is permitted but not mandatory.
-For load testing, the calibration of Load Cells, Hydraulic Jacks, Pressure Gauges & Pressure Transducers, Dial Gauges, and Linear Variation Displacement Transducers (LVDTs) must have been performed within the last six (6) months.
