3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 6931.1,
GB/T 6931.2 apply.
7.6 Antistatic properties
The antistatic properties of V-ribbed belts with antistatic requirements shall comply
with the requirements of GB/T 10715.
8 Test methods
8.1 Appearance
Check the appearance of the V-ribbed belt by visual inspection.
8.2 Size
The effective line difference of V-ribbed belt is measured according to the provisions
of GB/T 17516.2. The exposed height and effective length limit deviation of the V-
ribbed belt are measured in accordance with the provisions of GB/T 33513.
8.3 Tensile property test
The tensile strength and reference force elongation of V-ribbed belts are tested in
accordance with the provisions of GB/T 3686.
8.4 Low temperature resistance performance test
8.4.1 Specimen
The number of specimens is 3. Taken from the same sample tape. Cut a strip with a
length of not less than 250 mm as a specimen. If 3 specimens cannot be taken from one
sample belt, 3 specimens can be taken from the same model and batch of products, but
this shall be noted in the test report.
8.4.2 Test procedures
For ordinary V-ribbed belts, the specimens are pretreated at a temperature of (100±2)℃
for . The specimen is then cooled to room temperature and kept at (-30±1)°C for
. For heat-resistant V-ribbed belts, pretreat the specimens for at a
temperature of (120±2)°C. The specimen is then cooled to room temperature and kept
at a temperature of (-40±1)°C for . After taking it out, immediately conduct
bending tests on the corresponding cylinders according to the requirements of
Condition A and Condition B in Table 2. The bending arc must be at least 90°.
8.5 Fatigue life test
The length of the V-ribbed belt is based on the actual usage conditions or as agreed
between the supplier and the purchaser. Use a two-wheel, three-wheel or four-wheel
fatigue testing machine to conduct fatigue life testing in accordance with the provisions
of GB/T 41947.
8.6 Antistatic performance test
The antistatic performance of V-ribbed belts is tested in accordance with the provisions
of GB/T 10715.
9 Inspection rules
9.1 Exit-factory inspection
9.1.1 V-ribbed belts must be inspected by the manufacturer's quality inspection
department and issued with a certificate before leaving the factory.
9.1.2 The exit-factory inspection items of V-ribbed belts include appearance, size and
tensile properties.
9.1.3 V-ribbed belts shall be visually inspected one by one.
9.1.4 For the size of the V-ribbed belt, at least 3 shall be measured for each mold, and
1 shall be taken from the head, middle and tail. If one of them is unqualified, the molded
V-ribbed belt shall be fully inspected.
9.1.5 The number of V-ribbed belts of the same material shall not exceed 50,000 in one
batch. Sufficient samples shall be taken from each batch of products for tensile property
testing. If the monthly output is less than 50,000 pieces, inspection will be conducted
once a month. If the party has special requirements, relevant inspections can be decided
through negotiation between the supplier and the purchaser.
9.2 Type inspection
9.2.1 V-ribbed belts shall undergo type inspection at least once every six months. When
one of the following conditions occurs, type inspection shall be carried out.
a) During the trial production of new products or the finalization and appraisal of
old products for production transfer;
b) When the product is resumed after 2 years of discontinuation;
c) After the product is officially produced, if there are major changes in structure,
materials, and processes, it may affect product performance;
d) When the national market supervision and administration department puts
forward requirements for type inspection.
9.2.2 The type inspection items of V-ribbed belts shall include all items in Chapter 7.
9.3 Determination rules
9.3.1 Exit-factory inspection If one or both of the appearance and dimensions of the V-ribbed belt do not meet
the requirements of this document, the product will be judged as unqualified. If the tensile properties of the V-ribbed belt do not meet the requirements of this
document, double the number of specimens from the batch of V-ribbed belt products
shall be taken for re-inspection. If the re-inspection result is still unqualified, the batch
of products will be judged as unqualified products.
9.3.2 Type inspection The appearance and size determination of V-ribbed belts shall be carried out in
accordance with If the tensile properties, low temperature resistance, fatigue life and antistatic
properties of the V-ribbed belt do not meet the requirements of this document, double
the number of specimens will be taken from the batch of V-ribbed belt products, and
the unqualified items and related items will be reinspected. If one or more of the re-
inspection results are still unqualified, the batch of products will be judged as
