Testing Requirements
Testing is one of the most important parts of IS 2835 certification.
Current BIS LIMS information lists testing facilities for IS 2835:1987 and provides individual testing parameters and charges.
Testing parameters include:
1. Material
The material is evaluated against the applicable requirements.
2. Thickness
The thickness of the glass is checked against the specified requirements.
3. Length
The length is measured according to the standard.
4. Width
The width is evaluated against the applicable dimensional requirements.
5. Gaseous Inclusions
The glass is examined for specified gaseous inclusions.
6. Opaque Gaseous Inclusions
Opaque gaseous inclusions are checked against the permissible limits.
7. Knots, Dirt and Stones
The glass surface is inspected for these defects.
8. Scratches, Rubs and Crush
Surface defects such as scratches, rubs and crush are evaluated.
9. Bow
The glass is assessed for bow/curvature.
10. Reams, Light Strings and Lines
These surface/optical defects are evaluated according to the standard.
11. Waviness
The product is assessed for permissible waviness.
12. Sulphur Stains
The applicable requirement for sulphur stains is checked.
13. Corner Breakage and Chips
The glass is examined for corner breakage and chips.
14. Allowable Clusters of Defects
BIS LIMS also identifies testing for allowable clusters of defects for applicable quality categories.
BIS Testing Laboratory
BIS LIMS currently lists IS 2835:1987 in its laboratory scope.
For example, BIS Central Laboratory is listed for the standard, and BIS LIMS also lists other laboratories with IS 2835 testing scope.
Testing charges can vary depending upon:
- Laboratory
- Test parameters
- Product scope
- Testing package
- Number of samples
- Additional requirements
Therefore, current BIS LIMS charges should be checked before budgeting for certification.
BIS Testing Cost
Current BIS LIMS entries show different testing charges depending on the laboratory and scope.
One BIS LIMS listing for IS 2835 shows an overall testing charge of ₹25,000 excluding taxes, while another listing provides parameter-wise charges.
Therefore, manufacturers should not assume that ₹25,000 is the complete BIS certification cost.
The overall project cost may include:
- Application fees
- Testing charges
- Inspection expenses
- Licence-related charges
- Retesting, if required
- Documentation
- Consultancy fees
Factory Inspection Process
During factory inspection, important areas may include:
Manufacturing Facility
BIS may assess whether the factory has suitable manufacturing infrastructure.
Raw Material Control
Raw materials and their quality-control procedures may be reviewed.
Manufacturing Process
The manufacturing process should be documented and controlled.
Product Inspection
Finished glass should be inspected for dimensions and surface defects.
Testing Facilities
Required testing arrangements should be available.
Calibration
Measuring instruments should have valid calibration records.
Quality Records
Production and inspection records should be properly maintained.
Product Marking
BIS-related marking requirements should be followed after licence grant.
Common Reasons for Application Rejection or Delay
- Wrong Indian Standard selected
- Incorrect product classification
- Incomplete documentation
- Inadequate manufacturing facilities
- Product failing laboratory testing
- Dimensional non-conformity
- Excessive surface defects
- Inadequate testing arrangements
- Expired calibration certificates
- Missing quality-control records
- Incorrect product marking
- Incomplete application
- Failure to close BIS observations
- Factory not ready for inspection
Cost Factors
The total BIS certification cost depends on:
- Product scope
- Number of product variants
- Testing requirements
- Laboratory charges
- Application charges
- Factory inspection expenses
- Retesting
- Documentation requirements
- Consultancy support
Important: BIS certification cost should be quoted after assessing the actual product and manufacturing scope.
Timeline
The BIS certification timeline is not identical for every manufacturer.
It can depend on:
- Document readiness
- Factory readiness
- Sample availability
- Laboratory availability
- Testing results
- BIS application scrutiny
- Inspection scheduling
- Observation closure
A realistic timeline should therefore be provided after reviewing the manufacturer's actual situation.
