- What is DOP testing?
- DOP testing is the process where the integrity of your High Efficiency Particulate Air (HEPA) filter is tested by introducing Dispersed Oil Particulate (DOP). The filters are used in industrial equipment items such as fume hoods, negative air units and powerful vacuums.
- How is a DOP testing equipment prepared?
- A DOP testing equipment is prepared after the equipment is switched on. We use either a pneumatic or thermal aerosol generator. The aerosol photometer is set up according to the manufacturer’s instruction and attached to fitted upstream and sample points of each HEPA filter.
- What is a DOP filter test?
- Hence, DOP is often interchanged with poly-alpha olefin (PAO) tests. Other liquids used include DEHS and paraffin oil. DOP filter testing provides assurances for all parts of the filter including the filter housing, the seals and the joints.
- Which liquid is used in DOP tests?
- In the past, Di-Octyl Phthalate was used in DOP tests but Poly Alpha Olefin, a non-carcinogenic liquid is now preferred due to rising concerns about carcinogenic properties in the former. Hence, DOP is often interchanged with poly-alpha olefin (PAO) tests. Other liquids used include DEHS and paraffin oil.
- Why do you need a DOP test?
- Without a DOP test, there is a high risk of contamination to your cleanroom. It could impact your product quality and processes which in turn affect your cleanroom certification. A DOP test saves money, time, reduces cost product recalls and prevents damage to your brand.
- Who will carry out DOP testing for my specialised ventilation system?
- DOP testing for your specialised ventilation system will be carried by qualified engineers from Saakvee Technologies. DOP testing requires a full understanding of PD6609:2007, BS EN ISO 14644-3 (B.6), GMP (Good Manufacturing Practice) and expertise to address identified leakages in the ventilation system.
