Manual Electric ASTM D4318 Liquid Limit Machine Butterfly Type

Professional soil testing equipment for determining liquid limit and moisture content analysis in accordance with ASTM D4318 standards.

Applications

Designed to determine the liquid limit of soil samples, classify soil types, calculate natural consistency and stagnant index, and support engineering design and construction applications.

Technical Specifications

Electric motor drive with manual operation capability
Disk falling frequency: 120 hits/min (allowable error ±15%)
Built-in strike timer for precise measurements
Complies with ASTM D4318 standard test methods

Testing Methodology

This method determines soil liquid limit through multiple tests (minimum 3 repetitions) to establish a plastic flow curve (Flow Curve).

Available Methods:

One-point method: Calculate liquid limit from a single test
Inspection or identification test for verification purposes

The drop-dish method is standard unless otherwise specified. Inspection testing is recommended for inconsistent results or specific technical requirements.

Equipment Definition

The liquid limit represents the boundary water content between liquid and plastic states, expressed as a weight percentage of dried soil. The test measures the water content where soil paste flows together after 25 drops from 1 cm height with a 12.7 mm groove separation.

Required Equipment

Porcelain evaporating dish: 114.3 mm diameter
Soil conditioning knife: 76.2 mm length * 19 mm width
Liquid limit meter with copper plate and bracket
Groover with gauge for consistent sample preparation
Moisture-proof containers for sample preservation
Precision balance with 0.01 gram sensitivity

Sample Preparation

Prepare approximately 100 grams of soil sample passing through No. 40 sieve (425 microns) following ASTM dry preparation methods for particle fraction and soil parameter determination.
