Some standard content:
GB/T 10454--2000
This standard has made the following major changes to GB/T10454--1989:
1. Since the container itself is a flexible container, the name of this standard is officially changed from the original "Flexible Container Bag" to "Container Bag"; 2. The Japanese Industrial Standard JIS21651-1988 is revised to modify the dimensional tolerance of the container; 3. The nominal volumes listed in Tables 2 and 3 added to the standard are obtained by rounding off the actual volumes (to the nearest hundred), and the ratio of nominal volume to actual volume is 99% to 99.5%; 4. In order to ensure the safety of loading and unloading, the top hanging and side hanging structures in the original standard are cancelled, and all are bottom hanging structures; 5. Strengthen the technical requirements for container keying. This is the first revision of this standard.
Appendix A of this standard is a reminder appendix. This standard is proposed by China National Packaging Corporation. This standard is under the jurisdiction of the National Technical Committee for Packaging Standardization. The drafting units of this standard are: Standard Measurement Research Institute of the Ministry of Railways and Standard Metrology Research Institute of the Ministry of Communications. The main drafters of this standard are: Zhang Jin, Zhao Jingyu, Bai Zhigang, Xiong Caiqi 1 Scope

5 Tests
5. 1 Test environment conditions
The test is carried out at a temperature of <20±2)°C and a relative humidity of (65±5)%. Unless otherwise specified, the test piece should be placed under the above conditions one hour before the test.
5.2 Sampling requirements
Select the test sample from the base material of the nest bag or on the body. In case of dispute, the latter method shall prevail. 5.3 Test method
5.3.1 Dimension measurement
When the base fabric is not stretched, flatten the container bag. For a rectangular container bag, measure the diameter of two different parts and take the average value, and then convert it into the required diameter according to the folded diameter. For a square container bag, measure the upper and lower sides of two adjacent sides and calculate the average value of their side lengths. The height of the container bag is to measure the height of two different parts from the upper bottom to the lower bottom of the main body and calculate the average value. 5.3.2 Base fabric test
5.3.2.1 Preparation of the sample
Take 5 test pieces with a width of 60 mm and a length of 300 mm from the longitudinal and transverse directions of the sample (see Figure 2), and each test piece is measured to an accuracy of 50 mm. If the last thread is more than half a thread, it should be measured. Otherwise, it should be removed. 5-.3.2.2 Tensile strength and elongation test
Draw a 100mm mark in the center of the test piece (see Figure 2), and install it on the fixture of the tensile testing machine at a position about 25mm outside the mark. GB/T10454--2000
Stretch it at a speed of about 200mm/min until the test piece breaks. Measure the maximum load and the spacing between the marks at this time. The elongation can be calculated according to formula (2).
Elongation (%)):
Where: L-represents the spacing between the marks at the maximum load, mm. 1= 100× 100
Figure 2 Schematic diagram of base fabric sample
5.3.2.3 Cold resistance test
Take 2 test pieces with a width of 20mm and a length of 100mm from the longitudinal and transverse directions of the material, place the pieces in a constant temperature box at 35℃ for more than 2 hours, cut out the test pieces and fold them in half at 180° in the length direction, and check whether the base fabric material has any damage, cracks or other abnormal conditions. 5.3.2.4 Heat resistance test
Take 2 test pieces with a width of 20mm and a length of 30mm from the longitudinal and transverse directions of the sample. Overlap their surfaces, apply a load of 9.8V on them, and place them in a drying oven at 10℃ for 1 hour. After taking them out, immediately separate the two overlapping test pieces and check whether there are any other abnormal conditions such as adhesion, cracks, etc. on the surface. 5.3.3 Test method for slings and ropes
5.3.3.1 Sampling method
Take sling samples of appropriate length from the lifting ring of the container bag. The number of sling samples should be at least two. 5.3.3.2 Elongation test
The sample is mounted on a tensile testing machine. After applying a tension load of 196N, a 200mm spacing mark is drawn and pulled at a rate of about 100mm/min. When the load reaches 30% of the tensile strength F, the spacing of the marks is measured. The elongation can be calculated according to formula (3). Elongation (%) =
-200
2×100
Where: L- represents the spacing of the marks when the load reaches 30% of the tensile strength F, m blood. 5.3.3.3 Tensile strength test
The sample is mounted on the fixture of a tensile testing machine with a fixture spacing of 220mm, and stretched at a rate of about 100mm/min to measure the tensile strength at break.
5.3.4 Test method for joints
5.3.4.1 Sampling method
Take 5 test pieces with a width of 60mm in the longitudinal direction, a length of 300mm in the vertical direction, and a width of 25mm in the ear from the continuous sample (when cutting the ear and the central part of the test piece, be careful not to cut the seam line or cause scratches), and then accurately cut to 50mm width. If the last one exceeds half of the seam, it should be retained, otherwise it should be removed (see Figure 3). 5.3.4.2 Tensile strength test
GB/T10454—2000
Figure Schematic diagram of seam edge and seam bottom
Mount the test piece on the clamp with a distance of 200 11I on the clamp and a pulling speed of 200 mm/mil1, and measure the tensile strength when the test piece is broken. 5.3.5 Whole bag test method
5.3.5.1 Intermittent lifting test
Fill the contents evenly into the container until it is full, hang a load equivalent to twice the maximum load, do 70 times for limited-time bags and 30 times for one-time bags, and lift repeatedly. Whether the container bag is qualified depends mainly on whether there is any abnormality between the contents and the connection, and whether the connection is damaged. If there is no abnormality, it means that the test has been passed.
5. 3.5.2 Vertical drop test
Lift the fully loaded container bag with a lifting device, lift the bottom of the container bag more than 0.8m off the ground, and then step down vertically to the hard and flat ground once. If the contents do not overflow and the container bag body is not damaged, it means that the test has been passed. 5.3.5.3 Pressurization test
Put the fully loaded bulk bag on the pressurizer for a pressurization test. The pressure applied by the pressurizer is four times the full weight of the bulk bag, or the static load method is used, that is, the dead weight of four layers of fully loaded bags. The pressurization time is more than eight hours. In this test, the contents do not overflow and the body is not photographed, which means that the bulk bag has passed this test. 5.3.5.4 Tipping test
Stack the fully loaded bulk bags in three layers, then buckle the top bag with a rope and pull it down, and then observe its performance. In this test, the bulk bag does not have damage to the base fabric and stitching parts or other abnormal conditions, which means that the bulk bag has passed this test. 5.3.5.5 Upright test
Make the fully loaded bulk bag lie on its side on the ground, use a lifting device to hang one or two lifting ears of the bulk bag (if there are four lifting ears), lift it to an upright position at a speed of at least 0.1 H/s, and make it fully off the ground. In this test, if there is no abnormality in the body of the container and the connection between the bag body and the sling, it means that the container bag has passed this test. 5.3.5.6 Tear propagation test
Stand the fully loaded container bag upright on the ground, make a 100 mm1 incision at 45° through the main axis of the container bag at any part below the wound surface of the bag, then lift the container off the ground, keep it for five minutes, and then lower it to the ground. If the propagation of the length of the tear wound does not exceed 25%, it means that the container bag has passed this test.
