CRITERIA FOR DETERMINING THE PAPER CARTON images; Board - Determination of bursting strength tetrahedron letters STANDARD ISO 3228-2 VIETNAM: 2000 1. Scope of application This standard specifies methods for determining the resistance of the type of paperboard podium with resistance podium between 350 kPa to 5500 kPa. This method is also applicable for the type of paper and paperboard has low resistance to 250 kPa podium tetrahedron letters if they are used for the processing of these products have a higher resistance to the platform (such as laminated paperboard, paper making waves of paperboard wave). 2. Standards ISO 3649 cited: 2000 Paper and paperboard - Sampling to determine average quality. TCVN 6725: 2000 Paper, paperboard tetrahedron letters and pulp - Environmental Standards for Air and testing. TCVN 1270: 2000 Paper and paperboard - Determination of the amount. 3. Definition 3.1 platform is under the greatest pressure works perpendicular to the surface of the specimen shall be before the podium, in the standard test conditions. 3.2 The subject of the platform is the platform of the tong resistance to quantify its share. Principle 4. The sample is placed on the diaphragm plate made of elastic material and is clamped. Hydraulic fluid is pumped with a constant speed inflate the diaphragm until the specimen platform. Resistance podium of the tong is worth largest hydro pressure effects. 5. gauge under 5.1 platform. Clamping unit clamps to clamp the specimen ensure tight, uniform, non-slip during the test between the two sides recommend circles, tetrahedron letters parallel, smooth (but not the ball) and the groove as described in sub Contents A.1. Clamp on the disc is supported by a hinge or a similar body to ensure clamping tetrahedron letters pressure is distributed evenly. When testing the grooves in the sides of the disc sandwiched between 0,25mm to concentric and parallel to each other. Inspection methods are described in Appendix A.2. Clamping pressure should be sufficient so as not to slip during the test sample, but not too large will damage the sample. Generally, the pressure of not less than 690 kPa clamp (Appendix A.3). For corrugated cardboard, 690 kPa pressure clamp is enough to ruin the way the waves, so the statement must clearly damaging pressure wave lines. 5.2. Diaphragm Diaphragm is made of elastic tetrahedron letters material, circle, beneath the surface of the lower clamp plate about 5,5mm. Materials and structures of the diaphragm must ensure the following conditions: When applying a pressure of about 170kPa to 220kPa highly inflated to 10 mm above the bottom tetrahedron letters of the clamping plate. When applying a pressure of about 250kPa to 350kPa highly inflated to 18mm above the bottom of the clamping plate. The new diaphragms often need greater pressure to swell height as defined than the diaphragm was used. Bring compartment must be checked regularly and if you do not meet the new regulations must be replaced. When replacing the diaphragm must be very careful to avoid air in the lower diaphragm. 5.3. Hydraulic System Hydraulic system exerts increasing pressure on the underside diaphragm until the sample platform, the pressure generated by the motor control piston pushes the appropriate liquid (glycerol, purified etyleneglycol contains corrosion inhibitors or low-viscosity silicone oil) is located below the surface of the diaphragm. Hydraulic tetrahedron letters systems use liquids and not be any air bubbles. Speed Pump 170ml / min 15 ml / min. 5.4. 5.4.1 Pressure Gauges Pressure Gauges Bourdon format suitable measuring approximately 95mm in diameter or larger. Expansion of the gauges tetrahedron letters in about 15% of the specified value. 5.4.2 Gauge current form of precision of about 0.2%. 5.4.3 Pressure gauges are calibrated according to Appendix A.4. 6. Remove and sample preparation is taken from ISO 3649: 2000. The sample must have an area larger than the area of the disk clamp and is not used in the disc clamping portion of the previous attempts to try next time. The sample is not wrinkled, tetrahedron letters silhouette tetrahedron letters water or visible defects. Samples were conditioned in accordance with ISO 6725: 2000. The number of sample depends on the required test. If asked to define a surface resistance of each sample platform, the number of trials for the presence of 20 times. 7. How to Conduct a test conducted in environmental samples such as environmental conditioning. When the meter to select, then select Gauges about appropriate measurement by measuring tetrahedron letters the activity of the samples before a meter, about the highest measured. Lift the clamp plate, the sample in position measurement, the sample clamping pressure as specified tetrahedron letters in Article 5. The effects of pressure hydraulic correct speed until the sample platform. Reading rates
