Compressive strength refers to the maximum stress value that a material can withstand under axial compressive loading before failure (crushing or fracturing), typically measured in megapascals (MPa) or pounds per square inch (psi). In foreign trade, this term commonly appears in specifications for building materials (such as concrete and stone), metals, plastics, and packaging materials (such as cartons and foam). Usage scenarios include: contract technical annexes, quality inspection reports, product manuals, and inspection certificates required by letters of credit. Note: The test standard (e.g., ASTM C39, ISO 604) must be specified, as different standards (e.g., specimen size, loading rate) can lead to different results; also, compressive strength should be distinguished from compressive resistance (often used interchangeably, but strictly speaking, compressive resistance is the ability to withstand pressure without failure, while compressive strength is the ultimate stress at failure), tensile strength, and flexural strength. Foreign trade practitioners should specify the test method in the contract to avoid disputes arising from inconsistent standards.
📝 Examples
1. According to the contract annex, the compressive strength of this batch of granite must be no less than 150 MPa, and an ASTM C170 test report is required. (Note: Specifies the indicator and test standard as the basis for delivery.)
2. The customer complained that the cartons had insufficient compressive strength, causing collapse during transportation. Please provide a third-party inspection report to prove compliance with ISTA standards. (Note: Used in quality dispute and claim scenarios.)
💡 Foreign Trade Tips
Foreign trade terms are the foundation of international business communication
Trade practices may vary slightly by country; pay attention when using them
When using terms in contracts, specify the applicable version (e.g., Incoterms 2020)
