Glow wire testing evaluates how insulating materials respond when exposed to a heated electrical component, including whether ignition occurs and how long burning continues after the heat source is removed.

Precious metal verification often requires more than a karat stamp or traditional acid test. Qualitest’s October newsletter examines complementary methods for evaluating gold, silver, platinum, and related alloys across jewelry appraisal, scrap sorting, and quality-control workflows.

Heat can reveal developing faults long before they become visible through conventional inspection. Qualitest’s September newsletter explores thermal imaging from field diagnostics to detailed bench analysis, featuring QualiTC™ handheld cameras and QualiTCA™ thermal analyzers.

Products can pass routine inspection yet fail later as repeated thermal expansion and contraction weaken solder joints, seals, adhesives, and material interfaces.

Small differences in temperature, loading, timing, or operator technique can shift melt flow results even when the polymer itself has not changed.

Fluid contamination can accelerate component wear long before a hydraulic system shows obvious signs of trouble. Qualitest’s August newsletter examines the QualiOPC™ Series for particle counting across laboratory, field, and continuous online monitoring workflows.

Rising wear-metal levels can signal developing equipment problems well before a failure becomes visible in operation.

Abnormal wear can develop before gearboxes show visible or audible signs of failure, leaving maintenance teams with limited time to respond.

Uncertain ion measurements can delay regulatory review, complicate root-cause investigations, and weaken confidence in release decisions.

Failed tablet batches can delay release, increase investigation time, and expose gaps in formulation or process control.
