ASTM D3527: Are we using the right system to measure the life of a wheel bearing grease?

For more than three decades, international standards organization ASTM International has supported efforts to improve the accuracy of the ASTM D3527 High-Temperature Wheel Bearing Test — a method introduced to measure the performance and estimate the life of an automotive front wheel bearing. Released in 1976, ASTM D3527 is one of a myriad of industry … Continue reading ASTM D3527: Are we using the right system to measure the life of a wheel bearing grease?

‘Problematic’ tests pull handbrake on grease specifications

The National Lubricating Grease Institute (NLGI) “Grade” or “Consistency Number” is a function of how much thickener is used in the grease formulation. The more thickener employed, the stiffer the grease. NLGI’s classification defines nine grades, from a triple zero that is fluid, even at low temperatures, to a “very hard” grade six. NLGI grades … Continue reading ‘Problematic’ tests pull handbrake on grease specifications

Making aviation fuel more sustainable

Sustainable Aviation Fuel (SAF) may seem like a contradiction in terms, but this is the aim of the aviation industry, chemists, biochemists and engineers worldwide. Indeed, according to the International Air Transport Association (IATA), more than 132,000 commercial flights have been powered by sustainable aviation fuel since the first commercial flight in 2008. IATA is … Continue reading Making aviation fuel more sustainable
