About This Item
ASTM D470 is the ASTM standard for evaluating crosslinked insulations and jackets used on wire and cable. It provides a technical basis for testing materials intended to protect conductors and help confirm that finished cable components meet expected performance needs. For buyers, engineers, and quality teams, this standard is useful because it supports more consistent material assessment and helps align product evaluation with a recognized industry document.
What is ASTM D470?
ASTM D470, titled Standard Test Methods for Crosslinked Insulations and Jackets for Wire and Cable, sets out test methods related to crosslinked polymer coverings used in wire and cable construction. Its focus is on the insulation and outer jacket materials rather than the complete cable assembly. As an ASTM standard, it is commonly used to help evaluate material behavior in a controlled and repeatable way, supporting technical review, specification development, and product qualification.
Where is ASTM D470 used?
This standard is typically used in wire and cable manufacturing, materials testing, and product development work where crosslinked insulation or jacket materials are being assessed. It may also be relevant in procurement and quality control settings when comparing products against a defined testing reference. ASTM D470 is most useful wherever cable coverings need to be checked for consistency, performance characteristics, or compliance with an established test method.
Why is ASTM D470 important?
ASTM D470 matters because it helps bring consistency to the evaluation of crosslinked insulation and jacket materials. Using a recognized test method can reduce uncertainty in product comparison, support compliance efforts, and improve confidence in test results across suppliers or labs. For engineering and purchasing teams, ASTM D470 can be a practical reference for quality control, acceptance decisions, and technical documentation tied to wire and cable materials.
