| S.No. | Checkpoint | IS Requirement | Status |
|---|---|---|---|
| A. FRAME MATERIAL AND SPECIFICATION | |||
| A1 | Frame material type verified against design (steel, aluminum, UPVC, timber); manufacturing certificate available Acceptance: Material test certificates for steel (IS 1730, IS 1392); mill certificates for aluminum; quality assurance marks present | Cl. 4.1 — Material specification | OK NC NA HOLD |
| A2 | Frame dimensions and profile verified against design drawings (width, height, depth, section profile) Acceptance: Measured dimensions compared with design; tolerance ±2 mm for smaller dimensions, ±5 mm for larger; profile matches design section | Cl. 4.2 — Dimensional verification | OK NC NA HOLD |
| A3 | Frame surface finish: painting, powder coating, or anodizing (as specified) in good condition; no rust, chipping, or damage Acceptance: Paint/coating uniform; thickness per spec (typically 75-150 microns); no corrosion spots; touch-up areas visible but acceptable | Cl. 4.3 — Surface finish quality | OK NC NA HOLD |
| B. FRAME POSITIONING AND ALIGNMENT | |||
| B1 | Frame positioned correctly in opening: plumb (vertical) within 3 mm per 3 m height; level (horizontal) within 2 mm per meter width Acceptance: Spirit level or laser level used for verification; measurements recorded; deviations documented; acceptable if within tolerance | Cl. 5.1 — Plumb and level requirements | OK NC NA HOLD |
| B2 | Frame squareness verified: diagonal measurements difference ≤3 mm for typical door opening (≤2400 mm diagonal) Acceptance: Diagonal measurements taken and compared; difference within tolerance; frame not twisted | Cl. 5.2 — Squareness check | OK NC NA HOLD |
| B3 | Frame centerline aligned with opening centerline (no offset/shift); centered for symmetrical opening Acceptance: Offset measurement from opening edges: ≤5 mm difference from design centerline; frame sits symmetrically | Cl. 5.3 — Centerline alignment | OK NC NA HOLD |
| C. FRAME FIXING AND SECURING | |||
| C1 | Frame anchored to structure with approved fasteners (welding, bolting, or mechanical anchors per design) Acceptance: Fasteners spaced ≤500 mm vertically; ≥3 fasteners per jamb minimum; bolts/welds inspected; no loose fixings | Cl. 6.1 — Fixing method | OK NC NA HOLD |
| C2 | Welded connections (if applicable) inspected: beads smooth and continuous; no cracks, undercuts, or porosity visible Acceptance: Welds visually inspected; surface finish acceptable; filler material appropriate; no defects visible; weld thickness adequate | Cl. 6.2 — Weld quality | OK NC NA HOLD |
| C3 | Frame-to-structure gaps filled with approved material (mortar, foam, or sealant); no voids or gaps > 5 mm Acceptance: Gaps filled continuously; material applied to ≥50% depth minimum; final finish neat; no water ingress risk | Cl. 6.3 — Gap filling | OK NC NA HOLD |
| C4 | Frame movement test: applied force perpendicular to frame face; movement < 2 mm under hand pressure Acceptance: Frame fixed rigidly; no perceptible movement under moderate push; anchoring adequate for door/window weight and operational loads | Cl. 6.4 — Fixing security | OK NC NA HOLD |
