Although Derek's short-range compression tester (such as DRK113C) and compression tester (such as DRK113 series) belong to the same category of compression performance testing equipment, theyTesting principle, applicable scenarios, and structural designThere are clear differences on:

1、 Core Testing Principles and Applications

• Short distance compression instrument

  Specially designed for "short distance compression strength", pressure is only applied to a narrow area (usually 10mm width) of the specimen during testing, simulating the stress state of the cardboard at the corrugated peak.

  It is mainly used for short distance compression strength (SCT) testing of corrugated core paper and cardboard boxes, and is one of the core indicators of the burst and compression resistance of corrugated cardboard boxes.

• Compression tester

  It is a universal compression performance testing equipment that tests the compression performance of samplesThe entire contact planeApply uniform pressure.

  It can test various indicators such as ring compression strength (RCT), edge compression strength (ECT), and flat compression strength (FCT), and is widely used for comprehensive strength testing of cardboard and corrugated cardboard.

2、 Structural and design differences

• Short distance compression instrument

  equipNarrow width pressure plate (approximately 10mm in width)And the position of the pressure plate can be accurately aligned with the stress area of the sample, requiring the use of specialized fixtures to locate the sample.

  Structurally integrated with a pneumatic positioning system, ensuring the accuracy of the specimen under narrow pressure plates.

• Compression tester

  adoptLarge diameter flat pressure plate (usually with a diameter of 120mm)The surface of the pressure plate is flat and can be adapted to samples of different sizes.

  Most of them are double column or door type rigid frames, which can withstand greater compressive loads and support multiple fixture switching to meet different testing needs.

3、 Applicable standards and scenarios

• Short distance compression instrument

  Compliant with short distance compression testing standards such as GB/T 267911 and ISO 9895, mainly used forPerformance testing of raw materials for corrugated core paper and cardboard boxesProvide data support for the design of cardboard box structures.

• Compression tester

  Compliant with multiple standards such as GB/T 2679.8 (ring pressure) and GB/T 6546 (edge pressure), suitable forComprehensive performance testing of finished cardboard and corrugated cardboard boxesIt is a universal equipment for cardboard box factories and quality inspection agencies.
