Sliding Locking
Bolts are robust and versatile locking mechanisms designed to work seamlessly
with padlocks for enhanced security. These bolts are commonly used for doors,
gates, and cabinets, ensuring reliable protection against unauthorized access.
Made from durable materials, they are resistant to wear and corrosion, making
them ideal for both indoor and outdoor applications.
Their smooth sliding mechanism and sturdy construction ensure ease of use and long-lasting performance. Designed to meet stringent quality standards, these bolts provide an effective solution for securing properties across residential, commercial, and industrial sectors.
Who Needs BIS Certification for Sliding Bolts?
BIS certification under IS 7534:1985 is required for businesses involved in
manufacturing, importing, or selling these locking bolts in India.
Applicable to:
- Manufacturers – Producing bolts in India
- Importers – Bringing locking bolts from other countries into India
- Brand Owners—Selling product under their own brand name in the
Indian market
What is IS 7534:1985
This is the Indian Standard that specifies the quality, material, and construction
requirements for padlock locking bolts. It is issued by the Bureau of Indian Standards
(BIS) to ensure these security fittings are safe, durable, and suitable for reliable locking
applications.
This standard ensures that these products are:
- Manufactured to provide secure locking performance with padlocks
- Strong and durable enough to handle regular usage and mechanical stress
- Suitable for installation on doors, gates, cabinets, and similar applications
- Made with proper materials to resist wear and ensure long service life
Testing and Inspection Requirements for Sliding Locking Bolts
To ensure proper and reliable locking performance of these bolts, IS 7534:1985
specifies testing and inspection requirements, which are done during manufacturing.
What are R and S?
- R (Required): Test must be conducted in the manufacturer’s in-house laboratory
- S (Subcontracting Allowed): Test can be conducted in a BIS-approved or
NABL-accredited laboratory
Mechanical Strength & Performance Tests
- Load/Strength Test (R) – Ensures the sliding bolt can withstand applied locking
force without bending or failure
- Operating Smoothness Test (R) – Checks smooth sliding action during locking
and unlocking
- Durability Test (S) – Verifies performance under repeated opening and closing
cycles
Material Quality & Construction Tests
- Material Composition Check (S) – Ensures correct material grade is used for
required strength and durability
- Visual Inspection (R) – Confirms proper finish, surface quality, and absence of
defects
- Dimensional Check (R) – Ensures correct size, alignment, and fitting accuracy
as per standard requirements
Corrosion & Surface Protection Tests
- Corrosion Resistance Test (S) – Ensures the product can resist rusting under
normal environmental conditions
- Coating/Plating Inspection (S) – Checks quality of protective coating for
long-term durability.
Functional & Fitment Tests
- Padlock Compatibility Test (R) – Ensures proper fitting and smooth operation
with standard padlocks
- Locking Alignment Test (R) – Confirms correct alignment of bolt and locking
mechanism for secure operation
process for bis certification
The BIS
certification process for Sliding Locking Bolts for use with Padlocks involves
multiple steps, designed to thoroughly evaluate a product's compliance with the
required standards. Here is a general overview of the certification process:
- Application Submission: Manufacturers
must submit an application form along with required documentation to BIS.
- Documentation Review: BIS reviews the
submitted documents to ensure completeness and correctness.
- Factory Inspection: BIS officials
conduct an on-site inspection of the manufacturing facility to assess the
production process and quality control measures.
- Sample Testing: Product samples are
taken and tested in BIS-approved laboratories to verify compliance with Indian
standards.
- Certification Grant: Upon successful
completion of the inspection and testing, BIS grants certification, allowing
the manufacturer to use the BIS mark on their products.
