ايزو 1419:2019 هو المعيار الذي ينظم اختبارات الشيخوخة المتسارعة للمطاط – أو الأقمشة المغلفة بالبلاستيك. The purpose of this standard is to provide a standardized method for testing the resistance of rubber or plastic coated fabrics to accelerated aging caused by high temperature and humidity.

The standard specifies two methods for conducting accelerated burn-in tests: الطريقة أ, which involves exposure to high temperature and humidity in a controlled environment, and Method B, which involves exposure to an automatic sterilizer in high-pressure steam. Both methods are designed to simulate the effects of environmental conditions on long-term exposure to rubber or plastic coated fabrics.

This standard specifies test conditions, بما في ذلك درجة الحرارة, humidity and exposure time requirements. It also provides guidance on the preparation of test samples and evaluation of test results.

ايزو 1419:2019 applies to manufacturers and users of rubber or plastic coated fabrics to assess the durability and performance of their products. By conducting accelerated aging tests according to this standard, manufacturers can ensure that their products meet the requirements of intended applications and users can trust the durability and longevity of the products they purchase.

يقدم
Aging of coated fabrics involves subjecting specimens with previously determined properties to controlled deterioration over a known period of time. Choosing the most appropriate test method, aging time and temperature will depend on the purpose of the test and the type of coated fabric. The properties used to measure deterioration of the coated fabric may be strength properties, الانحناء, resistance, or any other desired physical or chemical properties. Its characteristics can be studied by selecting appropriate test methods.
