High-Frequency Reciprocating Tester is a fully automated, computer-controlled tribological testing system designed to evaluate fuel lubricity and the friction and wear performance of additives. It is widely used for friction and wear analysis of petroleum products and for measuring the lubricating properties of fuels, lubricating oils, greases, and additives. The new-generation system combines programmable control with high-precision piezoelectric ceramic sensors, enabling real-time friction force measurement with excellent repeatability and ease of calibration.

Application

The High-Frequency Reciprocating Tester is used in standardized and research-level lubricity testing, including:

Evaluation of diesel fuel lubricity and additive performance

Friction and wear analysis of petroleum products under boundary lubrication conditions

Lubricity measurement of lubricating oils, greases, and fuel additives

Comparative testing of different fuel formulations and additive packages

Research, development, and quality control testing in refineries, laboratories, and industrial facilities

Optional modules allow extended testing such as electrical contact resistance measurement, wear scar morphology observation, and gasoline lubricity testing.

Standards

The tester complies with or supports test methods defined in the following standards:

ASTM D6079 (Standard Test Method for Evaluating Lubricity of Diesel Fuels by the High-Frequency Reciprocating Rig)

GB/T 35137-2025 (Diesel fuel lubricity evaluation)

SH/T 0765 (Diesel fuel lubricity evaluation method)

ASTM D7688 (Standard Test Method for Evaluating Lubricity of Diesel Fuels)

ISO 12156-1 (Diesel fuel — Assessment of lubricity using the high-frequency reciprocating rig — Part 1: Test method)

CEC F-06-A-96 (Method for evaluating the lubricating performance of diesel fuel)

BS EN 590 (Automotive fuels — Diesel — Requirements and test methods)
