Abstract:
The Rubber Hose Outer Coating Wear Testing Machine is designed to evaluate the abrasion resistance of rubber hose coatings under controlled conditions. Compliant with international standards, it simulates real-world friction scenarios to measure coating durability. Key features include adjustable test parameters, precise data recording, and compatibility with diverse hose specifications. Ideal for quality control in automotive, industrial, and aerospace sectors, this equipment ensures reliability and safety of rubber hoses in harsh environments.

Applicable Standards:
The machine adheres to standards such as ASTM D3806 (Rubber Property—Abrasion Resistance), ISO 6945 (Rubber-Coated Fabrics—Abrasion Resistance), and SAE J300 (Automotive Hose Testing). It also supports custom protocols for specialized applications.

Main Parameters (Table 1):

Working Principle:
The tester uses a rotating abrasive wheel (e.g., sandpaper) to apply controlled friction to the hose coating. A specimen is clamped horizontally and subjected to reciprocating or circular motion against the abrasive surface. The load and speed are preset via a digital controller, while a counter records cycles until coating failure (e.g., exposure of base material).

Test Principle:
Abrasion resistance is quantified by measuring the weight loss or thickness reduction of the coating after a defined number of cycles. The machine calculates the abrasion index (volume loss per unit distance) to compare material performance. Advanced models integrate laser sensors for real-time thickness monitoring, enhancing precision.

Applications:
Widely used in R&D and manufacturing of hydraulic hoses, fuel lines, and industrial hoses, this tester ensures compliance with safety standards and extends product lifespan by optimizing coating formulations.
