Technical details and manufacturing context for Reference Standard Holder

Definition

The Reference Standard Holder is a critical component within a Reference Standard Station that provides precise, stable mounting for reference standards. It ensures proper alignment and repeatable positioning of calibration artifacts, preventing movement or vibration that could compromise measurement accuracy. The holder typically interfaces with the station's positioning system and may include features for thermal stability, electrical isolation, or environmental protection depending on the application. Constructed from materials such as stainless steel, aluminum alloy, or ceramic composite, the holder is designed to accommodate standards up to 50 mm in diameter with a clamping force adjustable between 100 and 500 N. Positioning accuracy is specified as ±0.01 mm, and repeatability as ±0.005 mm, both referenced to ISO 230-2. The operating temperature range is 10–40 °C, outside which accuracy may be affected. The standard material grade is SUS304 (ASTM A276), with surface hardness of HRC 40–45 (ASTM E18). The holder weighs between 2.5 and 4.0 kg and has dimensions of 150×100×80 mm (L×W×H). Mounting is via M6 threaded holes (ISO 965-1). These parameters serve as directory reference ranges; actual values must be confirmed for the specific model and application. The holder's working principle involves mechanical clamping, vacuum chucks, or kinematic mounts to secure the standard, maintaining precise geometric relationships with measurement probes. Some designs incorporate temperature control or vibration damping to minimize environmental influences. For procurement, verify model-specific specifications and standards with the legal manufacturer or supplier.

Working Principle

The holder mechanically secures the reference standard using clamping mechanisms, vacuum chucks, or kinematic mounts. It maintains precise geometric relationships between the standard and measurement probes/sensors. Some designs incorporate temperature control elements or vibration damping materials to minimize environmental influences on the reference standard during calibration procedures. The clamping force is adjustable to secure without deformation, and the positioning accuracy ensures repeatable placement. The holder interfaces with the station's positioning system, allowing for precise alignment. Verification of clamping force and positioning accuracy should be performed according to the manufacturer's instructions.
