ASTM F88
応募書類
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.
テストプロセス
- 準備: Cut test specimens from the sealed package, ensuring they are uniform in size.
- 設定: Mount the specimen in the testing device, with each end of the seal gripped by the machine.
- テスト: Apply a tensile force to the specimen at a constant rate until the seal separates.
- 測定: Record the force required to separate the seal.
テスト結果の解釈
- 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.
テストの意義
- 品質管理: Ensures the integrity of packaging, preventing contamination or spoilage.
- コンプライアンス: Helps meet industry standards and regulatory requirements for packaging.
- Product Safety: Confirms that seals can withstand handling, transportation, and storage conditions.
機器要件
- 引張試験機: Capable of applying controlled tensile force.
- グリップ: Suitable for securely holding the test specimen without slipping or damage.
- 較正: Regularly calibrated to ensure accuracy and repeatability of results.
予防
- 標本の準備: Accurate cutting and handling to avoid pre-test damage.
- 機械の校正: Ensuring the testing machine is correctly calibrated.
- Test Conditions: Conduct tests under consistent environmental conditions to avoid variability.
