PFINDER 860
PFINDER 860 is a hydrocarbon-free, directly water-washable color contrast penetrant for crack detection of surfaces. PFINDER 860 is readily biodegradable according to ISO 9888 / Zahn-WellensEMPA test (OECD 302 B). Details and test report available on request. Due to its removability PFINDER 860 provides only a low residual background even on rough surfaces and therefore a user-friendly interpretability of the indications. PFINDER 860 is qualified for penetrant testing at temperatures between – 20 °C to + 100 °C (temperature of work part) according to EN ISO 3452-5 and EN ISO 3452-6. Penetrant type II according DIN EN ISO 3452-1. Use: Type II, Method A + C, Form a, b, c, e, f.
APPLICATION The capability of the penetrant system should be checked regularly by means of own reference pieces or e.g. reference test block 2 according EN ISO 3452-3. Process description according DIN EN ISO 3452-1 see www.pfinder.com. For applications at temperatures below + 10 °C and above + 50 °C, penetration time has to be adapted as follows: + 100 °C to + 50 °C: penetration time up to 10 minutes + 50 °C to + 10 °C: according DIN EN ISO 3452-1 and EN ISO 3452-2 + 10 °C to 0 °C: usual penetration time x 2 0 °C to – 10 °C: usual penetration time x 3 - 10 °C to – 20 °C: usual penetration time x 4 Values are referring to the temperature of the working part. Aerosol spray cans must not be warmed up above + 50 °C.
