The smoothness tester is used for the determination of smoothness of paper and board according to Bekk Method. It conforms to ISO527, DIN 53107, TAPPI T-479, GB/T 456 standards.

This  Tester determines the smoothness of the sample in  seconds. This instrument is especially suitable for very smooth surfaces. such as coated label papers or coated free sheets. It creates a vacuum and measures the time it takes for the vacuum to drop from 50.66 to 48.00 kPa. Alternatively, the time it takes for the pressure to drop from 50.66 – 29.33 kPa can be set. The instrument is supplied with a 1/1 vacuum chamber and a 1/10 chamber. Very smooth papers are tested at 1/10 of the volume to safe time.

Principle

Bekk smoothness: time in seconds which under a defined pressure differential is required to draw a definite quantity of air at atmospheric pressure between the surface of the test piece and a ring-shaped plane surface under specified conditions of contact.

Elmendorf type tear tester for film measures the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started. It helps to rank relative tearing resistance of various plastic films and thin sheeting of comparable thickness. Elmendorf type tear tester for film principle: Acting by gravity, the pendulum swings through an arc, tearing the specimen from a precut slit. This loss in energy indicates the force required to tear the specimen.

Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades. The liquid limit data of soils is useful to correlate mechanical properties of soil, such as compressibility and lower shear strength. Liquid limit is the water content at which soil passes from zero strength to an innite strength, hence the true value of liquid limit cannot be determined. For determination purpose liquid limit is that water content at which a part of soil, cut by a groove of standard dimensions, will flow together for a distance of 1.25cm under an impact of 25 blows in a standard liquid limit apparatus. The soil at the water content has some strength which is about 0.17N/cm. sq. (17gms/sq.cm.) At this water content soil just passes from liquid state to plastic state. It consists on a brass cup held on an adjustable bracket. The cup can be adjusted for a fall of 1 cm and can be raised an dropped on a rubber base of standard hardness by cam action. Complete with one Casagrande grooving tool, one ASTM grooving tool and a height gauge block. Same as above but fitted with a counter to register the number of blows.
