Compression Test

In foreign trade, 'Compression Test' typically refers to applying vertical pressure to packaging, containers, or materials to evaluate their compressive strength and tolerance during stacking and transportation. It is commonly used for testing cardboard boxes, pallets, plastic bottles, etc., to ensure goods are not damaged by stacking during storage and ocean shipping. Usage scenarios include: pre-export quality inspection, customer requests for test reports, carrier assessment of packaging compliance, etc. Notes: Test standards (e.g., ASTM D642, ISO 12048), test speed, maximum load, and deformation must be specified; different materials (corrugated paper, plastic) require different test methods; results must be compared with industry standards or customer specifications. Difference from 'Drop Test': compression test evaluates static stacking strength, while drop test evaluates dynamic impact tolerance; difference from 'Vibration Test': the latter simulates transportation vibration environments. If a foreign trade contract stipulates 'passing compression test', the specific standard, sample quantity, and acceptance criteria should be stated to avoid disputes.
