This test helps in determining the thickness of paint plating, coatings and galvanization on iron steel.

 Test Method: IS: 6745-1972 

Condensing Humidity:

This test helps in determining the resistance of organic coatings by controlled condensation. Condensation is produced by exposing the test surface of the sample to a heated, saturated mixture of air and water vapor, while the reverse side of the sample is cooled under air of room temperature air.

 Test Method: IS: 101 (P-6) (SEC-1)1988 

 

Crosshatch Adherence:

This test helps in determining the adhesion of a large variety of coatings.

 Test Method: 

 

Cyclic Corrosion:

This test helps in determining the corrosion degradation of coating systems for steel bridges.

 Test Method: 

Drying Time:

This test is done to know when a coating is totally dry. When developing a process, it is crucial to know the definite time it would take for the coating to dry or cure. The coating’s drying time involves multiple stages.The first stage is when coating levels off under gravity. Once it starts to cure, a thin dry film appears on the surface. The coating then continues to dry till the coating is totally cured.

 Test Method: IS: 101 (P-3) (SEC-4)1986 

Failure Analysis:

This test helps in determining when, where, and how the paint or coating failure can occur

 Test Method: 

Falling Weight:

The ability of a pipe coating to avoid mechanical damage during handling, shipping, and installation depends on its impact resistance. This test method provides a systematic means for screening coating materials aligned to this property.

 Test Method: 

Flexibility:

 

This test helps in determining the ability of a coating system to withstand the stresses of fabrication. Organic coatings on pre- coated sheet are subjected to stresses when fabricated into products by roll forming, brake bending, or other deformation processes. These stresses can exceed the flexibility or adhesive strength of the coating, resulting in fracture of the coating which exposes the surface, or in the loss of adhesion of the coating on the surface.

 Test Method: 

Free Falling Sand Abrasion:

The abrasive is allowed to fall from a specified height through a guide tube onto the coated panel until the substrate becomes visible. The amount of abrasive per unit film thickness is reported as the abrasion resistance of the coating on the panel. Both silicon carbide or silica sand can be used.

 Test Method: ASTM D968 

FTIR:

Fourier-Transform Infrared Spectroscopy (FTIR), can serve as an important first-line analysis tool for the identification of coating types and drying mechanisms via monitoring of the functional groups on the chemical compounds inherent in the formulation.

 Test Method: 

Gloss (60deg.C):

Gloss measurement is an essential instrument where a cosmetic appearance of the coat finish is required. It measures guide to control and test right from matte to mirror finish accurately. Multi- directional beam of light at a specific angle to the test surface and measuring the amount of reflection is used to determine gloss. For general gloss measurement the 60Å angle is recommended.

 Test Method: IS: 13607-1992, IS: 5691-1970 

Hardness:

This test method covers a procedure for rapid, inexpensive determination of the film hardness of an organic coating on a substrate in terms of pencil leads of known hardness. This test covers the determination of the indentation hardness of organic materials such as dried paint, varnish and lacquer coatings, when applied to an acceptable plane rigid surface, for example, metal or glass.

 Test Method: ASTM D3363 / ASTM D1474 

Impact resistance:

Impact performance after painting can be tested with a puncture test or a falling dart test.

 Test Method: IS: 101 (P-5)(SEC-3)1999 

Moisture Content:

This test helps in determining the total water content of paints using a calcium hydride reaction test kit, for water content between 2 % and 85 % water.

 Test Method: 

Peel:

 

This test is used to measure resistance to cracking (flexibility) and adhesion of attached organic coatings on substrates of sheet metal or rubber-type materials.

 Test Method: 

Penetration Resistance:

The penetration resistance is of special importance to architectural finishes. The ability to maintain a consistent appearance (color and gloss) on substrates with varying porosity can be checked by applying the paint over a coated and uncoated area of test chart. Thus, the penetration resistance is tested under extreme conditions. The penetration resistance is visually evaluated and can also be objectively evaluated by measuring color and gloss.

 Test Method: 

Salt Spray:

The salt spray test is a standardized test method used to check corrosion resistance of coated samples.

 Test Method: IS: 2074-1992, IS: 13183-1991, IS: 13607-1992 

Scratch Resistance:

The scratch resistance can be established e.g. in the Taber abrasion test, where the amount of haze is established after a number of abrasive cycles. The scratch resistance can also be measured by measuring the weight loss after a number of sanding cycles. The pen test determines the indentation caused by a sharp pencil scratched on surface with a defined force.

 Test Method: ISO 1518 

Scrubbing Resistance:

This test helps in determining the resistance of paints to erosion caused by scrubbing. Although scrub resistance tests are intended primarily for interior coatings, they are sometimes used for exterior coatings as an additional measure of film performance.

 Test Method: 

Spark Testing:

One of the most important properties of a thin film coating is the adhesion between the coating and the substrate. Scratch Tester is the most common method of accurate measurement of thin film coating adhesion. 

 Test Method: 

XENON Arc:

This test helps in determining the ability of a paint or coating to resist deterioration of its physical and optical properties caused by exposure to light, heat, and water can be very important for many applications. This practice may induce property changes associated with end use conditions, including the effects of sunlight, moisture, and heat. The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena such as atmospheric pollution, biological attack, and salt water exposure.

 Test Method: ASTM D6695 – 08 

Volatile Content:

This test helps in determining the weight percent volatile content of solvent-reducible and water-reducible coatings.

 Test Method: ASTM D2369, IS: 101 (P-2) (SEC-2)1986 

Water Content:

The amount of water that paint coat could absorb is measured by the water content test.

 Test Method: IS: 101 (P-2) (SEC-1)1988 

Water Resistance:

Water can cause the degradation of coatings, so knowledge of how a coating resists water is helpful for assessing how it will perform in actual service.

 Test Method: IS: 101 (P7SC-1)1989, IS: 13183-1991, IS: 5691-1970
