SUMMARY: This Technical Newsletter intends to inform users of Filter Monitors (FM) of delays in the development of possible new replacement technologies for FM. Consequently, despite the impending withdrawal of EI 1583, the continued use of FM cannot be entirely phased out before the end of year 2020 as originally anticipated by the industry. It is therefore unavoidable that the use of FM will continue in JIG Standards for an interim period beyond 2020. In this transition period, all actions defined in JIG Bulletin 105 shall be strictly adhered to for all FM systems still in use.
