| Property | Change after 70h/100°C in IRM 903 oil | | :--- | :--- | | Mass change | +5% to +15% (swelling) | | Volume change | +5% to +18% | | Hardness change | -5 to -15 points (softer) | | Tensile strength change | -20% max |

Recommendation

• Buy/use this PDF only if: You must verify compliance with an old specification, or your customer/market specifically demands "DIN 53357" as a test method.
• Otherwise, use DIN EN ISO 178 (current, harmonized across Europe). If you already have access to ISO 178, you generally do not need DIN 53357.
