2 SCHEME OF TESTING AND INSPECTION FOR CERTIFICATION OF TARPAULINS MADE FROM HIGH DENSITY POLYETHYLENE WOVEN FABRIC ACCORDING TO IS 7903: Laboratory - A laboratory shall be maintained which shall be suitably equipped and staffed to carry out the different tests in accordance with the methods given in the Indian Standards. 2. Test Record - All records of analysis and tests shall be kept in suitable forms approved by the Bureau of Indian Standards. 2.1 Copies of any records that may be required by BIS shall be made available at any time on request. 2.2 Quality Control - It is recommended that, as far as possible, Statistical Quality Control (SQC) methods may be used for controlling the quality of the products as envisaged in this Scheme [See IS 397(Part 1), IS 397(Part 2), IS 397(Part 3) & IS 397 (Part 4)] The instruments/equipments are required to be brought under calibration control, as per frequency to be decided depending upon the usage. 2.3 In addition, effort should be made to gradually introduce a Quality Management System in accordance with IS/ISO Standard Mark The standard mark as give in column (1) of the first schedule of the licence shall be screen printed with indelible ink or label affixed on each Tarpaulin made from High density polyethylene woven fabric provided always that the Tarpaulin made from high density polyethylene woven fabric conform to every requirement of the specification. 4. Marking In addition, each tarpaulin made from high density polyethylene woven fabric shall be legibly marked with the following information at one side of a corner either by providing on a tag or by printing on it with indelible ink: a) Manufacture s name & address and Trade Mark; b) Dimensions (size of tarpaulins) and mass (g/m 2 ); c) Batch No/Control Unit No.; d) Month and year of manufacture; e) Any other information required by the law in force; and f) Licence No. (CM/L ) 5. Packing The tarpaulins shall be packed as agreed to between the buyer and the seller

3 6. Levels of control The tests and inspection as indicated in Table 1 and at the levels of control specified therein, shall be carried out on the whole production of the factory which is covered by this Scheme and appropriate records and charts maintained in accordance with paragraph 2 above. All the production which conforms to the Indian Standard and covered by this licence shall be marked with the Standard Mark. 7. Control Unit:- For the purpose of this scheme, all tarpaulins made from same batch of laminated HDPE woven fabric (using same variety of basic fabric) and having same manufacturing particulars manufactured under similar condition in a day shall constitute a control unit. 8. Raw Material 8.1 HDPE Tapes - Tapes shall be manufactured from HDPE granules, which shall be UV stabilized by adding suitable UV stabilizer or carbon black. The tape, if manufactured by using carbon black shall contain minimum 2.5 percent of carbon black by mass when tested as per IS 2530 and the finished tarpaulins shall meet the requirements of UV stability & colour fastness to light as given Table 1 of IS 7903: HDPE Fabric - Tarpaulins shall be manufactured from HDPE woven fabric so that finished tarpaulin meets the requirements given in 5.2, 5.3 and Table 1 of IS 7903:2011. In case of Manufacturer s producing the tarpaulin from brought out woven fabric, every consignment should be accompanied with test certificate from supplier, indicating that the tapes used in woven fabric conforms to Cl.3.1 and 3.2 of IS 7903: Laminating Film The HDPE fabric used in manufacturing tarpaulin shall be laminated as per clause 3.3 of IS 7903: Eyelets - Used in the manufacture of tarpaulins shall be as specified in clause 3.4 of IS 7903:2011. Metallic eyelets shall conform to dimensions as per IS 4084: Line/Cord Beading - A line/cord beading of minimum of 2.5 mm diameter shall be provided along the length and width of the tarpaulins. 9. Construction:- Tarpaulins shall be constructed as per clause 4.1 of IS 7903: Bonding shall be as per clause 4.2 of IS 7903: Fixing of eyelets shall be as per clause 4.3 of IS 7903: Rejection - A separate record shall be maintained giving information relating to the rejection of units of Tarpaulins made from High Density Polyethylene Woven fabric which do not conform to the specification and the method of their disposal. Such material, if packed in containers, shall in no case be stored together with that conforming to the specification.

4 11. Samples - The licensee shall supply, free of charge, the sample or samples required in accordance with the Bureau of Indian Standards (Certification) Regulations from his factory or godown.
