FIRESTOP.

THE STANVAC STANDARD

Seal the opening. Protect the cables.

Sealed opening. Coated cables. Installation illustration.

A fire-rated wall still needs a tested seal.

Fire and smoke cross unsealed openings.
Flames can also spread along the cables.

01

Specify the Indian standard.

NBCS 2026 / PART F / THROUGH-PENETRATION FIRESTOPS

1.

NBCS SPECIFIES ONLY

IS 12458:2019

2.

IS 12458:2019 requires BOTH tests:

FIRE TEST + HOSE-STREAM TEST

3.

FM / UL alone is not sufficient.

FM / UL certification or ASTM reports alone do not establish
IS compliance or Indian authority approval.

4.

A 2-hour wall needs a 2-hour seal.

Seal gaps around cables and pipes with a tested firestop.
The seal must match the fire rating of the wall or floor.

Part F, 3.5.4.4: minimum 120 minutes for applicable cable/conduit openings.

NBCS 2026 replaces NBC 2016. State bye-laws and local fire-authority requirements
govern project acceptance.

02

Match the seal to your opening.

03

Protect the cable as well.

1.

1 foot of EC 43. Included free.

At every penetration. Intumescent coating controls flame spread.

EC 43 General: 240 min / IEC 60332-3 in the tested cable assembly.

OPTIONAL CIRCUIT AND PANEL PROTECTION

2.
EC 43 Survival

Fire-pump, alarm and trip circuits.

Full-length circuit survival: 240 min at 750°C.

IEC 60331-21.

3.
EC 7034

Thin panel wires. Fire + rodent protection.

Flexible. Translucent.

120 min / IEC 60332-3-22 Cat A.

4.
DC 52

Fire-retardant finish over internal panel paint.

04

4 reasons to specify STANVAC.

1.

Tested to the standard NBCS specifies.

FIREX tested at CSIR-CBRI, a Government of India laboratory.
IS 12458:2019: fire test + mandatory hose-stream test.

2.

Protection at both fire paths.

2-hour firestop at the opening + cable flame-spread protection.
1 foot of EC 43 at every penetration. Included free.

EC 43: 240-min IEC 60332-3 result in the tested cable assembly.

3.

One name answers for the whole system.

Four chemistries: mortar, barriers, cable coatings and panel finishes.
Survey, specification, drawings, method statements and trained applicators.

4.

Why pay more for FM / UL alone?

Competitive installed cost for the IS-tested seal + free cable coating.
Compare complete installed offers with imported alternatives.
