Plain Gypsum Plaster Board Testing(IS 2095 Part 1:2011)
Testing of plain gypsum plaster boards per IS 2095 (Part 1):2011 — dimensions, mass per unit area, transverse breaking load, and moisture performance — for false ceilings, drywall partitions and lining acceptance.
What is Gypsum Plaster Board Testing?
Gypsum plaster boards line the ceilings and partition walls of practically every modern commercial interior in India. IS 2095 (Part 1):2011 — Gypsum Plaster Boards: Plain Gypsum Plaster Boards — specifies their required dimensions and tolerances, mass per unit area, and minimum transverse breaking load for each thickness class, since an under-strength board sags between ceiling channels and fails at fixings.
Global Lab samples boards per the standard, conditions them, and verifies dimensional compliance, mass per unit area, and breaking load in both directions (longitudinal and transverse to the paper liner) on a calibrated flexural rig, with gypsum plaster raw-material tests available per the IS 2542 method series. Reports give per-thickness-class verdicts for acceptance and vendor qualification.
How the Plain Gypsum Plaster Board Testing is Conducted
- 1
Sampling & Conditioning
Boards are sampled per IS 2095 rules and specimens conditioned at the specified temperature/humidity to constant mass before testing. - 2
Dimensions & Tolerances
Length, width, thickness and edge profile are measured at specified points and checked against the per-class tolerances. - 3
Mass per Unit Area
Conditioned specimens are weighed and mass per square metre computed against the specification range for the thickness class. - 4
Transverse Breaking Load
Specimens are tested to failure on a flexural rig in both board directions; the minimum breaking load per IS 2095 (Part 1):2011 for the class is applied. - 5
Reporting
Dimensional, mass and strength results with per-clause compliance verdicts are issued via Autovity QLMS.
