The following is a summary of the revised/new certification requirements.

Action is Not Required for current certified products and the new/revised certification requirements will be applied in evaluation of the new and revised products effective September 18, 2015.

Section Paragraph Clause / Summary of requirements
4.2 / Requirements for level of protection “da” were introduced for the first time, permitting flameproof evaluation for catalytic sensors of intrinsically safe portable combustible gas detectors for use in Zone 0.
4.4 / Requirements for level of protection “dc” were introduced for the first time, permitting flameproof evaluation of “dc” devices for Zone 2.
6.1.2 / Cemented Joint evaluation permitted if leakage is detected during the overpressure test with blotting paper
6.2 / Requirements were added for fused glass to metal joints commonly used for insulating electrical feed-through pins.
13.6.4 / Permits construction for plugs and sockets to remain flameproof during the arc-quenching period while opening a circuit under specified load conditions.
16.3 / Welded enclosures that pass a 4x type test can use common industry methods for examining the integrity of the welds.
16.6 / Batch testing permitted for routine testing
Annex G / A new Annex G introduces requirements for equipment with an internal source of release of a flammable gas such as a process line for analysis.
Annex H / A new Annex H introduces requirements for inverter fed electrical machines.
