Stainless steel sinks for domestic purposes are widely used in kitchens for washing
utensils, vegetables, and other daily household tasks. These sinks are popular because
they are durable, rust-resistant, easy to clean, and suitable for long-term use in wet
conditions.
To ensure the quality and safety of these sinks, the Bureau of Indian Standards provides BIS certification as per IS 13983. This certification confirms that these steel sinks meet the required standards for material quality, strength, finish, and performance.
what is is 13983:1994
IS 13983 is the Indian Standard for stainless steel sinks used for domestic purposes,
mainly in kitchens for washing utensils and food items. This standard is set by the
Bureau of Indian Standards to ensure that sinks are safe, durable, and suitable for
regular household use.
This standard ensures that these kitchen sinks are:
- Safe and hygienic for daily kitchen use
- Strong enough to handle regular load and impact
- Resistant to rust, corrosion, and water exposure
- Properly designed for efficient drainage and usage
- Smooth in finish and free from defects
- Consistent in size, thickness, and manufacturing quality
Testing and Inspection Requirements for Stainless Steel Sinks
To ensure proper and efficient performance of these kitchen sinks used in domestic
purposes, the Bureau of Indian Standards has defined clear testing and inspection
requirements under the standard, which are carried out during manufacturing to ensure
that sinks are strong, well-finished, and suitable for daily kitchen use.
What are R and S
- R (Required): Test must be done in the manufacturer’s own laboratory
- S (Subcontracting Allowed): Test can be done in a BIS-approved or external
laboratory
Physical and Quality Tests
- Dimensions and Tolerances (R) – Ensures correct size, thickness, and
uniformity of sinks
- Construction and Workmanship (R) – Checks proper design, joint quality, and
overall structure
- Finish Test (R) – Ensures smooth surface, proper polishing, and no defects
Material Tests
- Raw Material Quality (S) – Confirms stainless steel meets required standards
and is ISI marked or certified
Performance and Strength Checks
- Thickness Measurement (R) – Ensures adequate strength and durability
- Structural Strength Check (R) – Ensures the sink can handle regular kitchen
load and usage
Process and Consistency Checks
- In-Process Quality Control (R) – Regular checks during manufacturing for consistent quality
- Hourly Sample Testing (R) – Samples are tested at regular intervals during
production
- Batch/Control Unit Testing (R) – Ensures sinks from the same lot meet
standard requirements
- Marking and Labelling Check (R) – Ensures proper ISI marking and product
identification
process for bis certification
The BIS
certification process for Stainless Steel Sinks for Domestic Purposes involves
multiple steps, designed to thoroughly evaluate a product's compliance with the
required standards. Here is a general overview of the certification process:
- Online Registration:
Manufacturers register on the BIS Manak Online Portal by submitting company
details, factory information, and product specifications. Foreign manufacturers
must appoint an Authorized Indian Representative (AIR) in India.
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories to evaluate electrical
safety, insulation resistance, heating efficiency, durability, and overall
performance as per requirements.
- Application Submission: The application is submitted along with laboratory test reports, technical
documents, manufacturing process details, and factory information. Foreign
manufacturers must also provide AIR-related documents.
- Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing unit to verify
production processes, quality control systems, safety measures, and compliance
with the standard.
- Grant of BIS License: If all requirements are successfully met, BIS issues the certification license under
Scheme-I, allowing the manufacturer to produce and sell certified products.
- Use of ISI Mark: After certification approval, the manufacturer is permitted to use the ISI mark
along with a CM/L number on the product, confirming compliance with the
standard.
