What testing standards does the 2810-005 support?

The Instron Coefficient of Friction Fixture is designed to test in accordance with ASTM D1894 and ISO 8295, the two most widely used standards for measuring static and kinetic coefficient of friction in plastic film and sheeting.

Will this fixture work with the testing system I already have?

The fixture mounts using Instron's standard Type D base grip adapter and connects to the load cell via a Type C coupling, so it's adaptable to most standard universal testing instruments — not just Instron systems with matching fittings. Check with our applications team to confirm compatibility with your specific frame.

Can I test both sides of my material in one setup?

Yes. The test specimen can be mounted to the sled, the table, or both, depending on what your standard or material requires — giving you flexibility to test film-on-film, film-on-metal, or other combinations.

Is this fixture suitable for high-speed friction testing?

No — the 2810-005 is designed for tensile-mode (standard-speed) testing only and is not intended for high-rate or high-speed friction applications. If your application requires higher-speed testing, let us know and we can help identify the right alternative.

What is coefficient of friction testing and why does it matter for plastic film?

Coefficient of friction (COF) testing measures how easily one surface slides against another — in this case, how easily plastic film or sheeting slides against itself or another material. It matters because friction affects how film behaves in real-world use: too much friction can cause jamming or tearing during high-speed packaging and manufacturing processes, while too little can cause slipping, poor stacking stability, or product mishandling. Manufacturers test COF to ensure film performs consistently on packaging lines, in shipping, and in end-use applications.

What's the difference between static and kinetic coefficient of friction?

Static coefficient of friction measures the force needed to start moving one surface against another from a resting position — essentially, how much resistance there is to overcome before sliding begins. Kinetic (or dynamic) coefficient of friction measures the force needed to keep the surfaces moving once sliding has already started. Static friction is typically higher than kinetic friction, and both values matter for different reasons: static friction relates to how film behaves when stationary (like on a stack or roll), while kinetic friction relates to how it behaves once in motion (like running through packaging equipment).

What equipment do you need to test coefficient of friction on plastic film?

At minimum, you need: a universal testing system (or equivalent frame) capable of controlled, constant-speed horizontal pulling; a coefficient of friction fixture, which includes a weighted sled and a flat test table or plate; a load cell sensitive enough to accurately capture low-force readings; and a tow line connecting the sled to the load cell. You'll also need testing software to run the test and calculate results — Instron's Bluehill® Universal software includes a pre-built ASTM D1894 test method, so you can start testing right out of the box or customize it to match your specific procedure.

概覽

Instron^® 2810-005 摩擦係數夾具可根據 ASTM D1894 和 ISO 8295 測量塑膠薄膜與片材的靜態和動態摩擦係數。加重滑塊在固定水平工作台上被拉動，同時荷重元記錄所需力量 — 為您的品質控管與研發團隊提供精確且可重複的摩擦數據。

此夾具使用 Instron 標準的 Type D 底座夾具轉接器，可直接安裝於您的萬能材料試驗機，讓您無需購買專用設備即可在現有機架上增加摩擦係數測試功能。

優點

隨心測試 — 可將試樣安裝在滑塊、工作台或兩者上，以便根據您的材料與測試需求調整夾具設置。
立即開始測試 — 隨附尼龍和金屬牽引線，無需額外採購零件即可準備測試。
沿用現有設備 — 適用於大多數標準萬能材料試驗儀器，保障您在測試設備上的現有投資。

應用

用於品質控管、進料檢驗及研發的塑膠薄膜與片材摩擦測試
拉伸模式摩擦係數測試（不適用於高倍率/高速應用）

運作方式

牽引線穿過導輪將滑塊連接至低力值荷重元。當橫樑移動時，滑塊被拉過工作台，荷重元會記錄整個測試過程中的力量：

靜態摩擦係數根據負荷曲線上的第一個力值峰值計算
動態摩擦係數根據兩個定義點之間的平均力值計算
摩擦係數 = 記錄的力量 ÷ 滑塊質量

常見問題（FAQ）

2810-005 支援哪些測試標準？

Instron 摩擦係數夾具旨在根據 ASTM D1894 和 ISO 8295 進行測試，這兩項是測量塑膠薄膜與片材靜態和動態摩擦係數最廣泛使用的標準。

此夾具是否適用於我現有的測試系統？

我可以在一次設置中測試材料的兩面嗎？

此夾具是否適用於高速摩擦測試？

什麼是摩擦係數測試？為什麼它對塑膠薄膜很重要？

摩擦係數 (COF) 測試測量一個表面在另一個表面上滑動的難易程度 — 在此案例中，即塑膠薄膜或片材在其自身或其他材料上滑動的難易程度。這很重要，因為摩擦力會影響薄膜在實際使用中的表現：摩擦力過大可能導致高速包裝和製造過程中發生卡塞或撕裂，而摩擦力過小則可能導致打滑、堆疊穩定性差或產品搬運不當。製造商測試 COF 以確保薄膜在包裝線、運輸及最終應用中表現一致。

靜態摩擦係數與動態摩擦係數有什麼區別？

靜態摩擦係數測量使一個表面從靜止狀態開始相對於另一個表面移動所需的力量 — 本質上是開始滑動前需要克服的阻力。動態摩擦係數則測量在滑動開始後保持表面移動所需的力量。靜態摩擦力通常高於動態摩擦力，且這兩個數值因不同原因而具有重要意義：靜態摩擦力與薄膜在靜止時（如堆疊或捲繞）的表現有關，而動態摩擦力則與其在運動時（如通過包裝設備）的表現有關。

測試塑膠薄膜的摩擦係數需要哪些設備？

您至少需要：一台能夠進行受控、恆速水平拉動的萬能材料試驗系統（或同等機架）；一個摩擦係數夾具，包括加重滑塊和平面測試台或板；一個靈敏度足以精確捕捉低力值讀數的荷重元；以及一條連接滑塊與荷重元的牽引線。您還需要測試軟體來執行測試並計算結果 — Instron 的 Bluehill® Universal 軟體包含預設的 ASTM D1894 測試方法，因此您可以立即開始測試，或根據您的特定程序進行自訂。
