Direct Shear test Apparatus
Direct Shear test Apparatus (Product Code: SLE/CE/58) is a split shear box with a loading unit used to measure the shear strength of soil on 60 × 60 × 25 mm specimens in soil mechanics laboratories. Normal stress up to 8 kg/cm² is applied directly or through a counter-balanced lever, and a 200 kg proving ring with dial gauges records the response. The apparatus is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Direct Shear Test Apparatus Used For?
The direct shear test gives a soil’s cohesion and angle of shearing resistance, the two parameters used in foundation, slope and retaining-wall design. A specimen trimmed with the cutter is placed between gripper plates and porous stones in the two-part box, the normal load is applied through the yoke, and one half of the box is displaced relative to the other so the soil fails along the horizontal plane. The proving ring measures shear force while the dial gauges record horizontal and vertical movement.
Repeating the test at several normal stresses plots the failure envelope. Perforated gripper plates with porous stones allow drainage, while plain plates suit undrained work. It is standard engineering lab equipment in India for geotechnical practicals; keep the roller strips clean, check the porous stones are not clogged, and zero both dial gauges before each run.
What to Specify When Ordering
- Normal stress range: the standard 3 kg/cm² weight set, or also the additional set for 5 kg/cm²
- Soil sampler for 60 × 60 mm specimens and test form pads

Frequently Asked Questions
What specimen size does the Direct Shear test Apparatus use?
The Direct Shear test Apparatus (SLE/CE/58) tests square specimens 60 × 60 × 25 mm in a two-part shear box. A specimen cutter for trimming 60 × 60 × 25 mm specimens from larger samples is included, and a soil sampler is available as an option.
What normal stress can the Direct Shear test Apparatus apply?
The loading unit of the Direct Shear test Apparatus has a normal stress capacity of 8 kg/cm². The standard weight set gives 3 kg/cm², an additional set for 5 kg/cm² is optional, and load is applied directly or through the counter-balanced detachable lever.
What is included with the Direct Shear test Apparatus?
The Direct Shear test Apparatus includes the two-part shear box, plain and perforated gripper plates, porous stones, a top loading pad, the housing with two ball roller strips, a specimen cutter and weights, plus a 200 kg proving ring and two 0.01 mm × 25 mm dial gauges.
Are spare porous stones available for the Direct Shear test Apparatus?
Yes. Spare porous stones for 60 × 60 mm samples are listed as available in pairs for the Direct Shear test Apparatus. Stones can clog with fine soil over time, so laboratories that test often usually keep a spare pair ready.
Who manufactures the Direct Shear test Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Direct Shear test Apparatus as the OEM at its own factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to buyers in India and international markets.
Is a calibration certificate available for the proving ring?
Calibration-certificate availability for the proving ring and dial gauges of the Direct Shear test Apparatus should be discussed with us before ordering. Tell us your documentation needs through the contact page and we will confirm what can be provided.
