BIS ISI Certification for PVC Sandals: Know Everything

PVC sandals are more durable and robust than conventional rubber or leather footwear. However, their quality may vary as per the type of PVC compound used in their production. Since there is a great demand for PVC sandals in India, their standardization has become an absolute necessity. In the status quo, every PVC sandal manufacturer must abide by the BIS norms and hence register their products under ISI marking scheme. To qualify for this scheme, products must pass different tests as mentioned in IS 6721:1972. Read on to discover more about the BIS ISI certification for PVC sandals.

An Overview of Indian Standards IS 6721:1972

Indian Standards IS 6721:1972 pens down the quality, testing, and labeling requirements for PVC sandals manufactured via the injection molding[1] process. Fundamentally, the S 6721:1972 encompasses the two types of sandals:

  • Type 1: One-part sandals
  • Type 2: Two-part sandals

The PVC sandals should comprise a material as recommended by the standard. The final design of the sandal should align with the norms of IS 1638:1960.

General Requirements around the Type 1 and Type PVC Sandals

Type 1 PVC sandals should adhere to unibody construction achieved via injection moulding. On the contrary, the Type 1 PVC sandals must stick around parting design construction achieved via injection moulding. The PVC sandals must withstand burning, shrinkage, wrapping, and cold flow marks.

Mandatory Tests under BIS ISI Certification for PVC Sandals

The following are the tests to be performed by the BIS-certified lab to determine the overall quality of the PVC sandals:

  • Relative Density Test
  • Tensile Strength Test
  • Hardness Test
  • Tear Strength Test
  • Volatility Test
  • Elongation Test
  • Test For Lead

The above tests should be performed in a well-equipped lab and as per the guidelines cited in the governing standard. The sole of each sandal must reflect the standard marking concerning the size, trademark, ISI, and manufacturer’s name.

Every sandal manufacturer must secure BIS registration to qualify for the ISI marking scheme. The BIS conducts a thorough examination of the production premises, testing capabilities, and quality control for possible non-conformity.

The inspection protocols also involve the collection of samples for which certification is required. During the visit, the officials will also scrutinize the manufacturing process and quality management system.

Step 3: Specimens testing and Report Generation

Collected samples will find their way to the BIS-accredited lab, which will test each sample for quality. Post conducting all the required tests, the lab pens down their finding in a test report. The notice of test report generation shall be shared with the applicant via registered contact details. The applicant, in response, should ensure the timely collection of the report and submit it to BIS as it adheres to limited validity.

Step 4: Issuance of BIS ISI Certification for PVC sandals

The lab report shall be scrutinized by the BIS for any possible error. If the authority fails to identify any loophole in the report, the grant of registration will come into effect. The grant of the certificate shall authorize the manufacturer to use the ISI marking on their products.

Is It Mandatory To Renew BIS ISI Certification For PVC Sandals?

Indeed it is! A BIS ISI Certification for PVC sandals or any other products comes with 1 year of validity. The renewal application should be attested by the practicing CA before submission.
