BIS-certified products have a distinct image in the marketplace because of their unparalleled quality. The plumbing industry extensively used BIS standards for manufacturing a wide range of UPVC pipes and fittings to cater to different plumbing applications. Unlike portable drinking pipes, UPVC pipes used in Soil and Waste discharge systems adhere to different characteristics and properties, which make them more durable and long-lasting. The standard called IS 13592:2013 specifies the production and quality norms for such pipes. The Standard also mandates pipe manufacturers to affix BIS standard markings on their products before putting them into sale. This article will brief the procedure and requirements concerning BIS certification for UPVC Pipes for soil and waste discharge systems.
What The Role Is Of IS 13592:2013 In UPVC Pipe Manufacturing?
IS 13592:2013 is an Indian standard that has been derived and formulated from various other standards such as IS 4985: 2000, IS 4669: 1968, and so on.
The standard pens down the requirements around plain and socket end unplasticized polyvinyl chloride possessing a nominal outside diameter of 40-315 mm applicable to soil and waste discharge systems fitted inside and outside buildings including rainwater, ventilation, and rainwater harvesting applications.
Essentially, the following types of pipes are covered under the standard:
- Type A: for use in rainwater harvesting and ventilation pipework.
- Type B: For use is waste and soil discharge systems
Requirements to Be Followed By the Pipe Makers to Qualify For BIS Certification for UPVC Pipes
Following are some requirements to be followed by the pipe makers to qualify BIS Certification for UPVC Pipes:
- Polyvinyl chloride should be the base material for pipe manufacturing.
- Manufacturers can add additives to make the pipe durable, robust, and mechanically sound. But those additives should not pose any danger to the nearby environment or human beings.
- As per the testing requirement cited under IS 4669, the pipe composition should be mainly constituted of PVC resin with a K-value equivalent or greater than 64.
- Pipes should easily withstand varying climate conditions and rough handling, causing distortion or bend.
- Pipes’ integrity should remain intact after coming in contact with chemicals present in the soil.
- Pipes should show no sign of leakage during the water tightness test
- Pipes’ appearance, colour, density, and strength should remain uncompromisable during their service life.
Documents Required for BIS Certification for UPVC Pipes
An applicant seeking BIS Certification for UPVC Pipes for Soil and Waste Discharge Systems must arrange the following documents:
- Business registration documents such as Certificate of Incorporation, MoA, and AoA.
- Factory license
- Trademark registration if available
- Process flowchart of pipe manufacturing
- List of machines present in the production facility
- List of testing equipment and their calibration report
- Details of Quality Management System and Standards followed by the manufacturer.
- Specimen testing report granted by the certified lab.
- Authorization letter issued by the company’s CEO delegating authority to applicant for addressing license formalities.
Process of Obtaining BIS Certification for UPVC Pipes for Soil and Waste Discharge System
The section below briefs the process of BIS certification for UPVC single-wall corrugated pipes:
Step 1: Application Filing
The process of securing BIS certification commences with the application filing. The form is available on the BIS portal. After filling out the mandatory details in the form, proceed to upload documents as discussed earlier and in the format advised by the authority.
After this, complete the fee submission formalities to successfully submit the form.
Step 2: Application vetting and sample testing
The next step that comes after the application submission is the application vetting and on-site inspection performed by the BIS officials.
During vetting, the officials will thoroughly check the quality management system for non-compliance by taking BIS norms into account.
This will also include sample selection based on the method cited in the Indian Standard.
The officials will dispatch the selected sample to the certified BIS labs for mandatory testing. Some of these tests shall include
Step 3: Sample Testing and Report Generation
The selected samples will undergo the following tests for any non-conformity. These tests will be conducted as per the requirements specified in the relevant Indian Standard.
Step 4: Report Collection
Once these tests are performed successfully, the lab will generate its report enclosing its findings pertaining to product performance.
The intimation concerning report generation will soon be shared by the lab with the applicant.
In response, the applicant must ensure the timely collection of the report since it adheres to the limited validity.
Step 5: Report Review and Grant of Certificate
After report collection, the applicant is required to submit the same to the BIS for the final assessment, which will lead to the grant of BIS certificate.
After securing the registration, an applicant can start marking their product with ISI marking.
Marking and Labelling Requirements for UPVC Pipe Makers
The UPVC pipe makers must meet the marking norms of the applicable Indian Standard. Each pipe should be affixed with the following details:
- Identification and source of manufacture
- Nominal outside diameter (in mm);
- Length (in m);
- Batch number
- ISI marking
So, that is all about the BIS certification for UPVC Pipes for soil and waste discharge systems. The new manufacturers may find it tedious and time-consuming to comply with pre and post-BIS norms. That is why it is advisable to seek assistance from professionals who are well-versed in this particular area.
