--- Part 2. temperature and humidity of the treated samples;
--- Part 3. Determination of moisture content (oven drying method);
--- Part 4. Determination of dimensions;
--- Part 5. Determination of characteristics of concentric rotation;
--- Part 6. Determination of flexural strength (three-point method);
--- Part 7. Determination of modulus of elasticity (three-point method);
--- Part 8. Determination of natural frequency and the elastic modulus (experimental modal analysis);
--- Part 9. Determination of flat crush strength.

Principle 3
With between three points on a plane perpendicular to the axis of the specimen was measured, in which two points have been determined in advance, and the other points along the measuring direction
mobile.
With five points between the plane perpendicular to the axis of the specimen was measured, four points have been determined in advance, that is perpendicular to the axis of the two samples
Plane twenty-two be determined at another point in a plane perpendicular to the axis of the specimen was measured along the direction of movement.
4 Instrument
Test equipment (Figure 1) consists of a holder (1) and carry out its support of two movable roller frame (2). Each roller frame and
By two support rollers (3), with the spacing between these two support rollers is adjustable. Diameter of the support roller is 85mm ± 1mm, to support wide roll
20mm ± 1mm. For example, you can choose 6209 supporting roller bearings.
With two measuring sensors were measured. Wherein a sensor (4) mounted above a roller frame, in addition to a sensor (5) Security
Mounted on the carriage, the sensor can be moved between two roller frame. The minimum scale sensor dial is 0.01mm, and accurate to
0.015mm, the measurement range is 50mm, the pressure sensor measuring approximately 1.2N, the minimum scale spacing is 0.01mm. Sensor
The probe should be 10mm diameter circular plane.
