The sample must be completely satured with water before the test, and the operator will check the rate of fall of the water in the tube passing through the test specimen. Falling Head Permeability Set consists of stand with 4 pcs. manometer tubes with connection valves, a Ø100mm permeability cell, soaking reservoir tank and connection hoses.
The falling head permeability test is used to determine the permeability of fine grained soils with intermediate and low permeability such as silts and clays with permeability in range of 1x10-5 to 1x10-9.This testing method can be applied to an undisturbed sample.

3. Improvement of the Soil-Cement Permeability Testing Apparatus. According to the Specification for Mix Proportion Test of Cement-mixed Soil (JGJ/T 233-2011) [], a truncated cone specimen is used for the permeability test.However, Equation (8) only applies to a cylindrical specimen and the permeability of the deteriorated layer cannot be measured using existing permeability testing apparatus.
Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a pattern.In a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.
Sand Testing Laboratory Resource Center. Casting defects not only affect quality, they impact your profit margin and competitiveness too. Unfortunately, recognizing casting defects is one of the most challenging burdens confronting metalcasters.

Acrylic tanks feature flow control regulating valve and bottom porous media to filter out air bubbles. Overflow port maintains constant head and allows for connection to water line or deaired water source.
4 and 6in Compaction Permeameters measure constant or falling-head properties of compacted or remolded soils and are designed for use with 4in (102mm) or 6in (152mm) Soil Density Mold Sets or Components.The permeameters offer rugged construction, wear-resistance, and long life. Upper and lower plates made of anodized aluminum are equipped with inlet/outlet connectors and valves to …
Figure 9.3 shows the schematic diagram for the constant head permeability test. The equipment for the test, known as permeameter, consists of a cylindrical mold, a drainage cap with an inlet valve and an air release valve, and a drainage base plate with an outlet pipe. The mold is 10 cm in diameter and 12.73 cm in internal height.
Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions.
