1.描述

離岸經營的立場是用來改進，壓腳正平行試樣表的準確性和模擬和數字硬度硬度計讀數的重復性。Any round og or dial durometer can be mounted on an applicable operating stand.任何一輪模擬或數字硬度可安裝在適用的經營場。展位的工作主要是為雙方與并行測試樣本使用。Irregularly shaped objects may be tested in a nest or a fixture to make the given surface parallel to the Durometer presser foot.形狀不規則的物體可能是在測試巢或夾具，使定表面平行的硬度壓腳。

ASTM D2240規定三類經營站：1類，2類，3。Te 1 are basic, manual operating stands.第1類是基本的，手動操作站。Te 2 are stands capable of controlling the rate of descent, and Te 3 are hydraulically, pneumatically or electromechanical driven.類型2的代表能夠控制的下降率，和類型3的液壓，氣動和機電驅動。Shore manufactures stands that fall into all 3 categories.站在岸上生產納入3個類別的下降。

2.操作原理

人工站幾種型號可供選擇。The LR leverloader features a constant load weight for highly accurate and reproducible hardness readings.土地注冊處leverloader具有高度準確，重現性硬度讀數恒定負載的重量。To operate, the lever is depressed to raise the specimen to the durometer, which in turn lifts a constant load weight seated on a shaft above the instrument.操作，杠桿低迷試樣的硬度，從而升降機恒定載重量在上述文書軸就座。The m of the durometer and instrument shaft embly in combination with the all weight produces the m necessary for Tes A, B, and O durometers.的硬度和組合儀表軸裝配質量的小重量群眾的生產類型的A，B和O硬度要的。The addition of the large weight produces the m necessary for Tes C, D, and DO durometers.在大重量除了大規模的生產類型的C，D，做要的硬度。The durometer and instrument shaft embly produces sufficient m for testing with Te OO durometers.硬度和儀器的軸裝配生產用于面向對象型硬度測試的質量。

在硬度應用速度的變化是不同的硬度讀數的共同事業。For example, when testing materials with high properties, you may obtain a false high reading if you apply the durometer too quickly to the material.例如，當高蠕變性能測試材料，您可能會得到一個錯誤的高讀數如果你申請的硬度太快的物質。The CV conveloader features a constant load weight and a hydraulic cylinder that automatically controls the application velocity of the durometer.該簡歷conveloader具有恒定負載重量和液壓缸自動控制的硬度應用速度。When you release the pawl lever, the weight drives the durometer downward at a steady rate, controlled by the calibrated bleed resistance of oil through the hydraulic piston.當您松開棘爪桿，重量硬度下降的驅動以穩定的速度，由校準流血通過液壓活塞耐油控制。The durometer contacts the specimen at a constant speed and force, ensuring repeatable and accurate test results.接觸的硬度試樣以恒定的速度和力量，可重復和的測試結果。

DR和DRCL（何恒定負載）代表提供一個穩定的安裝和測試模擬或數字硬度夾具。Both models allow you to adjust specimen table and durometer heights.這兩種型號允許你調整樣本表和硬度高。When a durometer is mounted and properly aligned, the durometer's presser foot is exactly parallel to the specimen table on the stand, ensuring accurate and repeatable readings.當安裝和硬度是對齊的硬度的壓腳，正是平行試樣表上的立場，準確和可重復的讀數。The DR stand requires that you manually lower the durometer and then apply appropriate pressure to the specimen.在何立場需要您手動降低硬度，然后采用適當的壓力，試樣。In contrast, the DRCL stand provides a loading weight of known value for this purpose.相比之下，DRCL立場為此提供了一個已知值裝載重量。
