📜 Relevant Indian Standards (IS Codes) for Your Woodwork

IS 1003 (Part 1): 1978 Specification for timber door, window frames – covers Salwood, chaukat dimensions, mortise & tenon joints. For 10cm x 8cm wrought frame, this IS recommends minimum section & quality grading.

IS 2202 (Part 1): 2009 Specification for panelled & glazed shutters – 4cm thick Deodar wood must meet moisture content (8-12%) and structural integrity tests.

IS 1331: 1992 Specification for iron fittings for windows and doors (hinges, tower bolts, aldrops). Ensures corrosion resistance & load capacity.

IS 14741: 1999 UPVC profiles for doors/windows – standard for UPVC door frames, material properties, and weatherability.

IS 14802: 2000 PVC door shutters – covers solid and hollow core PVC doors, fire resistance, and dimensional tolerances.

IS 919: 1993 Recommendation for timber work & joinery in buildings (general guidelines for deduction rules).

✂️ Deduction Rules for Woodwork (As per CPWD / IS 919)

When calculating net volume of Salwood frame or area of Deodar shutter, deductions must be made for openings, rebates, and joints. Standard practice for measurement of wooden frames & shutters:

📐 For Salwood Chaukat Frame (10cm x 8cm) – Volumetric Deductions

Opening / Feature	Deduction Rule	Applicable to Your Data
Mortise & tenon joints (corner joints)	No deduction for small interpenetration (standard practice). Volume measured as overall outer dimensions.	Frame volume 0.394 cu.ft → no reduction
Grooves / rebates for shutter seating	If rebate depth > 10mm, deduction of volume for removed wood is applicable (rarely deducted in BQ).	15cm rebate area: approximate deduction ~0.008 cu.ft (negligible for BOQ).
Openings for holdfasts or iron fittings	No deduction for small holes (less than 0.01 cu.ft each).	No deduction applied.

🪵 For 4cm Thick Panelled Shutter (Deodar) – Area Deductions (IS 2202)

Component	Deduction Formula	Example for 54 sq.ft Shutter
Panels (recessed area)	Gross area minus area of styles & rails if measured separately. For tenders, usually no deduction unless specifically itemized.	Standard practice: 54 sq.ft billed as gross area
Glass openings (if any)	If glazed area > 0.5 sqm, deduction for shutter area is applied (full deduction for void).	No glass in your panelled shutter.
Louver / ventilation gap	For each opening, 100% area deduction.	Not applicable.
Rebate & groove for panel	No deduction – considered part of manufacturing.	No deduction

💡 Important: As per CPWD specifications, when measuring panelled shutters (Deodar wood), the area is calculated without deduction for panels or beading — but if there are any through-and-through openings (like vents), full deduction applies. For your solid 4cm Deodar shutter, full 54 sq.ft is billable.

🔩 For Iron Fittings – Deductions & Norms (IS 1331)

No area/volume deduction for fixing holes in wood frame/shutter – they are part of hardware installation.
For each fitting, weight tolerance as per IS 1331: ±5% for hinges, bolts, handles.

📏 UPVC Door Frame & PVC Door – Deductions

For UPVC frame: measured in running feet (center line) – no deduction for corner joints or mitre cuts.
For PVC door: area measurement – no deduction for hinge recesses or lock cutouts.
If PVC door has vision panel (glass), deduct glass area above 0.2 sqm.

❓ 10 Frequently Asked Questions – IS Codes & Deduction Rules for Woodwork

1. Which IS code governs Salwood door frames?

IS 1003 (Part 1):1978 – covers timber frames including Salwood, minimum 10cm x 8cm dimensions, and permissible moisture content.

2. Are there deductions for mortise & tenon joints in frame measurement?

As per CPWD norms, no deduction for interpenetration of joints when measuring gross volume of chaukat frame. The 0.394 cu.ft remains fully billable.

3. For 4cm Deodar shutter, do I deduct panel recess area?

No. IS 2202 specifies that panelled shutters are billed as overall shutter area (style to style, rail to rail). Individual panel grooves are not deducted.

4. What IS code applies to wrought iron fittings?

IS 1331:1992 (specification for iron hinges, bolts, door handles). For quality assurance, ensure fittings carry ISI mark.

5. How to deduct for glass openings in a wooden shutter?

If glass panel exceeds 0.5 sqm, full area of opening is deducted from shutter area as per standard PWD deduction rules. Your project has no glass.

6. Are UPVC frames measured with any deduction for mitre cuts?

No, UPVC frames measured in running feet (center line). Corners do not reduce length as per IS 14741.

7. What is the standard deduction for rebate in Salwood frame?

Typically not deducted unless rebate depth > 12mm and specified. For 15cm rebate, volumetric effect is < 2% of total; usually ignored in billing.

8. Does IS 919 provide general deduction rules for joinery?

Yes, IS 919:1993 gives guidelines for measurement – deductions for openings > 0.5 sqm in area, but not for small hardware or panel grooves.

9. For iron fittings, is there any deduction in wood due to bolt holes?

Never deducted. The bolt holes are considered part of fitting installation and negligible in volume.

10. How do I apply deduction for a PVC door with louver?

If louvers are open (ventilation), area of opening should be deducted as per IS 14802. For solid PVC door, no deduction.
