ASTM F88

Материалы для подачи заявления

ASTM F88 focuses on determining the seal strength of flexible barrier materials. Common materials include plastics, foils, and laminates used in packaging industries such as food, pharmaceuticals, and medical devices.

Процесс тестирования

1. Подготовка: Cut test specimens from the sealed package, ensuring they are uniform in size.
2. Настраивать: Mount the specimen in the testing device, with each end of the seal gripped by the machine.
3. Тестирование: Apply a tensile force to the specimen at a constant rate until the seal separates.
4. Измерение: Record the force required to separate the seal.

Интерпретация результатов теста

• Peak Force: The maximum force recorded before the seal fails, indicating the seal strength.
• Mode of Failure: Observing how the seal fails (e.g., adhesive failure, cohesive failure, or substrate failure) provides insights into the seal quality.

Тест Значимости

• Контроль качества: Ensures the integrity of packaging, preventing contamination or spoilage.
• Согласие: Helps meet industry standards and regulatory requirements for packaging.
• Безопасность продукции: Confirms that seals can withstand handling, transportation, and storage conditions.

Требования к инструментам

• Машина для испытания на растяжение: Capable of applying controlled tensile force.
• Ручки: Suitable for securely holding the test specimen without slipping or damage.
• Калибровка: Regularly calibrated to ensure accuracy and repeatability of results.

Меры предосторожности

• Подготовка образцов: Accurate cutting and handling to avoid pre-test damage.
• Калибровка машины: Ensuring the testing machine is correctly calibrated.
• Условия испытания: Conduct tests under consistent environmental conditions to avoid variability.
