IS 10151:1982 is the Indian Standard (BIS) for methods of test for sealants for joints in civil engineering structures. IS 10151 provides test methods for evaluating sealants used in construction joints — expansion joints, glazing joints, and concrete movement joints. Tests cover adhesion, cohesion, elasticity, and weathering resistance. Referenced when specifying sealant performance for buildings and highways.

What tests should I request for sealant approval?+
Minimum: adhesion-in-peel (IS 10151 Cl. 3), cohesion under movement (Cl. 4), and UV weathering (Cl. 6). For structural glazing, add tensile adhesion and compression set.
What types of sealant are used in construction?+
Silicone (most common for glazing), polysulphide (chemical resistant joints), polyurethane (high-movement joints), and acrylic (low-cost interior joints). Each type has different IS specifications.
