IS 15868 : Part 1 to 6 : 2008 : Natural fibre geotextiles (jute geotextile andcoir bhoovastra) - Methods of test

1. Scope

1.1 This standard (Part 1) specifies a method for the determination of the mass per unit area of all natural fibre geotextiles for identification purposes and for use in technical data sheets.

1.2 The method is applicable to all natural fibre geotextiles, all coir bhoovastra, jute geotextiles and erosion control blankets (ECBs).

2. References

The mass per unit lila is calculated by weighing small square or circular specimens ofltnown dimensions. The mass per unit lilaofanECBis determinedby weighingtest specimens of known dimensions cut from various locations over the full width of the laboratory sample.

The measured weight is then used to calculate the mass per unit uea of the specimen, and these values are averaged to obtain the mean mass per unit area of the laboratory sample.
