BIS Certification for Multi Layered Cross Laminated Sheets and Tarpaulins/covers Under IS 14611

BIS CERTIFICATION FOR MULTI LAYERED CROSS LAMINATED SHEETS AND TARPAULINS/COVERS

Multi-layered cross-laminated tarpaulins are made of several layers of plastic film placed over one another in a criss-cross manner and bonded by a cold-roll technique. The resultant fabric is extremely strong yet lightweight.

This is an innovative complete protection, all weather cover made from multi-layered cross cut film, fused together giving it maximum strength and high durability.

Types of Tarp Materials

Tarps are made of a variety of materials depending on their use. Their main use is for covering, but they often need special characteristics such as strength, flexibility, and water resistance. Sometimes they may need to protect against extreme weather conditions like heavy sun exposure, storms,or strong winds.

The materials present in tarps are the basis for selecting the type of tarp to use. Tarps are classified based on different specifications, and the best material will depend on your needs.

Water resistance

Tarps are used to protect goods or spaces from rain or moisture. A water-resistant tarp is useful when you want to protect your goods. Tarps have a range of levels of resistance. Some tarps are completely waterproof while others are only slightly water-resistant.

Nylon

One of the most common materials in tarps is nylon, which has a very strong strength-to-weight ratio. Its elasticity is also a benefit for “stretching” in tarps and is extremely durable. Vinyl-laminated polyester tarps are fire retardant and waterproof, which makes them ideal for long-term outdoor use. 

Resistance to corrosion

Degradation easily results due to acids, oils, greases, mildew, and even sunlight. You should choose a tarp with a special resistance coating if you expect to use it in these conditions.

Strength

This is measured by the ability of a tarp to hold together when subjected to force. Materials used and the method used to weave play an important role in the strength of a tarp. Depending on where you will be using your tarp, it may need to be able to withstand strong winds without tearing or breaking.

BIS is a statutory institution established under the Bureau of Indian Standards Act,1986  to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.

Multilayered Cross Laminated Sheets and Tarpaulins/ Cover product has been specified in IS 14611:2016 by Bureau of Indian Standards.

This standard prescribes the requirements, constructional details, method of sampling and tests for multilayered cross laminated sheets, tarpaulins, covers and agricultural films intended for packing, ground covers (mulching), water conservation systems and fumigation covers, agricultural operations, horticulture, etc.

Plastic films for greenhouses are not cover under this standard. For plastic films for greenhouses a separate Indian Standard, IS 15827 has been published.

Importance of colors on tarps

The most common color of tarp is blue, and they are often seen on construction sites and trucks transporting corn or other food products. However, there are other colors of tarps; these colors sometimes have significance but it often depends on the company producing them. For example, one company might use red to signify dangerous materials while another company could use red to mean more visibility. There are no government regulations on specifications on the type of colors or their meaning on tarps, but companies generally follow similar color schemes.

Yellow, orange, and red

Red is mostly used to show visual importance for materials or dangerous places in construction sites. It reduces the risks of getting into an accident as it warns workers to use extra caution in these areas. You can also use the different colors to show different stages of construction. For instance, orange for the first stage, yellow second stage, and red third stage.

Black and dark grey

Most companies use these colors for heavy-duty tarps. They absorb sunlight rather than reflect it. They are ideal to transport asphalt that requires high temperatures.

White and silver

These tarps reflect sun rays and are mostly used to offer shade. They are applicable for tent canopies since they give a cool environment. White is most preferred for hot weather conditions since it is the best color that reflects sunlight and heat.

Brown, blue and green

This is one of the basic color tarps. Usually, it is used for basic and general-purpose tarps. It is meant for light industrial activities and consumer goods. Used for construction, contractors, farmers, and roofers.

The tarp color should be considered before you make a purchase. However, consult with the company before making any purchase to make sure the colors do not have different properties or uses.
