ASTM D1414 - Standard Test Methods for Rubber O-Rings
ASTM D1414 describes the standard procedures for determining the physical properties of rubber O-rings and the changes in those properties due to aging. Because the procedures are standardized, buyers can compare O-rings from different suppliers on the same basis, and quality teams can confirm that each production lot still matches the agreed specification.Watch: ASTM D1414: Will Your O-Ring Hold?

How to read an ASTM D1414 result
- Scope: ASTM D1414 covers the procedures for determining the physical properties of O-rings and the changes in those properties due to aging.
- Purpose: the methods are accepted procedures for quality control and for determining engineering characteristics, so each production lot can be checked against the agreed specification.
- Because the procedures are standardized, results from different suppliers can be compared on the same basis when specimen type and test conditions match.
- Aging changes the numbers: an O-ring that passes when new can lose properties after aging, which is why the standard covers the changes in properties due to aging.
- When qualifying a supplier, ask for ASTM D1414 by name and keep the specimen type and test conditions on record.
