Quality Control & Laboratory Testing
At Wire Iran, quality is integrated into every stage of production — from raw material selection to final batch validation. All WICSilicone products are tested in our ISO 17025-accredited laboratory according to certified procedures (ISO, DIN, JIS) for mechanical, thermal, electrical, and chemical performance.
Testing Criteria
| Category | Key Tests |
|---|---|
| Mechanical | Tensile strength · Elongation · Tear resistance · Shore hardness (A/D) · Rheometry (ML/ΔT) · Thermal shock |
| Electrical | Dielectric strength · Insulation resistance · Capacitance · Corona & tracking resistance (HV) |
| Thermal / Chemical | Heat aging · Thermal stability (TGA/DSC) · Oil/solvent immersion · Chemical resistance · Low-temp flexibility |
| Environmental | Salt spray · Weathering (UV/ozone) · Flame resistance (UL94 / FMVSS) · Humidity cycling |
Automotive components are subjected to flame resistance, thermal cycling, high-voltage insulation, megger, erosion, and salt spray testing, while silicone materials and molded or extruded products are evaluated for tensile strength, elongation, rheology, hardness, thermal shock, and insulation properties. In collaboration with the National Standard Institute since 2002, all products are validated for consistent performance and durability under defined automotive and industrial operating conditions.
Each batch is fully traceable and supported by certified documentation, including Certificates of Analysis (CoA), batch records, and compliance reports verifying conformity with FDA, USP Class VI, RoHS, and REACH standards. This ensures consistent reliability across medical, automotive, industrial, and food-grade applications.
