Область применения
This standard applies to innertubes of civil aircraft tyres. It specifies requirements, test methods, inspection rules, marking, storage, and usage. It is mandatory for manufacturers producing aviation tire inner tubes for the Chinese market. The standard covers both inch and metric size designations.
Технические требования
The standard mandates specific requirements for dimensional specifications, including thickness and weight limits for various inner tube sizes. It also specifies compatible valve types according to HG 2484 and HG 2485. A critical aspect is the airtightness performance, which must pass specific testing protocols. Additionally, the standard sets strict physical property limits for the rubber compound, including tensile strength, elongation at break, and tear resistance, as well as adhesion strength between components. Manufacturers must ensure no critical surface defects such as folds, sponging, or joint bubbles are present. The standard also defines mandatory marking requirements and strict storage conditions to prevent degradation, with a maximum combined storage and usage life of 5 years from the manufacturing date.
Методы испытаний
Testing includes airtightness tests (inflation parking test and water tank test), thickness measurements taken at specific points, and weight verification. Physical properties are tested per GB/T 15324, and adhesion strength per GB/T 532. Visual inspection is also required for surface quality.
