Rim latches are critical features in door locks and operations with high significance in homes, offices, and other buildings. In India, the Bureau of Indian Standards (BIS) has established IS 1019:1974, a specification standard that covers the description and the requirement of these important components. This standard helps to define the high quality of rim latches and thus raises the safety and reliability of cars.
The complexity of IS 1019:1974 starts to play a significant role as the demand for premium security hardware increases underpinning each door lock meeting people’s expectations and satisfying regulatory requirements. The BIS certification process forms an added advantage to these products to ensure that the customer receives a quality product that has been tested for its durability.
In this blog, we will delve into the various aspects of rim latches as per IS 1019:1974, relating to performance characteristics, methods of measurement, marking, and the procedure by which they would attain certification. To this end, this paper seeks to highlight the following topics to ensure a better appreciation of the impact of BIS standards in the manufacturing and quality control of rim latches used in doors across the country thus improving safety and security in day-to-day life.
IS 1019:1974 presents the measurable requirements of rim latches that are optimal components of door fasteners. This standard provides specifications of manufacturing, chemical, and physical characteristics required to maintain the quality and dependability of rim latches. It was established in the year 1957 and has been revised from time to time to reflect the current trend in manufacturing methodology and material. The latest revision strengthens the material specification by stating that only material conforming to particular Indian standards should be used and concerns itself with only using ISI standard materials for production.
The key characteristics outlined in IS 1019:1974 include:
Dimensions and Tolerances: Describes dimensions of rim latches which most normally were expressed in terms of overall length.
Material Quality: There should be standards where the latches should be made of, for instance, mild steel, brass, or aluminum forming an alloy.
Performance Criteria: This includes some tests on corrosion, endurance, and serviceability tests.
Workmanship Standards: They make sure that the latches are manufactured with very good workmanship so that they do not experience problems of quality.
The performance requirements of rim latches according to the IS 1019:1974 entail tests that check on the performance and robustness of the product. These tests help reinforce that the latches can pull through regular use without breaking off as intended. The primary performance criteria include:
Dimensional Checks: Check the dimensions of the latch against the given tolerance.
Durability Testing: They are conducted for an extended period to be able to mirror a given duration of use to ensure that the machinery can be depended upon when used for the whole duration.
Corrosion Resistance: They check how effectively the latch does not degrade when exposed to moisture.
Key Operation Test: Testing how well the latch complies with the use of a key.
These performance tests are important for understanding that rim latches meet safety and usability expectations by consumers.
Methods of testing for rim latches in accordance with IS 1019:1974 incorporate an array of procedures used in evaluating several performance characteristics. Key testing methods include:
Endurance Tests: Some latches are cycled normally to create the concept of usage for several years.
Pull-Out Tests: How much force is exerted to pull the latch out of its mounting.
Finish Adhesion Tests: Concerning evaluation of the performance of the finishes under stress or elements on the surface or substrate.
All these methods offer a complete appraisal of change latches used in products, making befitting methods as manufacturers examine latches to deliver first-class products.
Testing labs for plastic shoes need to follow certain rules:
Equipment: They must have the right tools that are checked and can do all the tests needed as per IS 1019:1974.
Qualified Staff: The people working there should have the right skills and training to do the tests correctly.
These rules are important to make sure the testing process is good and the results are reliable.
Proper labeling and marking are critical for identifying Rim Latches with IS 1019:1974. The standard specifies several key labeling requirements:
What Should Be on the Labels
Each article of Rim Latches must be marked with the following information:
Manufacturer's Name or Logo: This shows who made the Rim Latches.
Size Number: This explains the dimensions of the sole.
Batch Number: This serves to monitor the quality production batch.
Month and Year of Production: This is a testament to the time when the product was produced.
ISI Mark: This verifies that the product falls within the specifications of BIS.
Also, the packaging must follow BIS rules to ensure safe handling and storage during shipping.
The following are the required documents for BIS certification:
| General Documents | Technical Documents |
|---|---|
| GST Certificate | Raw Material List |
| MSME Or Udyam Certificate (Not applicable for large-scale industries) | Raw Material Test Certificate |
| Manufacturing land details (Lease Deed/ Rent agreement) | Plant Layout (Lab, Office, Raw material area, Finished Goods area) |
| MOA/AOA (If Private Limited) | Machinery List |
| Electricity Bill | Location Layout |
| Authorization Letter | Equipment List |
| QCI Adhaar Card | Process Flow Chart and Description |
| QCI Appointment Letter | NABL approved Calibration |
| QCI Degree Certificate | Product Specific Declaration as per clause no |
| Owner’s Pan Card | |
| Factory License |
The BIS certification process for Rim Latches involves several steps:
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that the manufacturers need to understand so that they can get an efficient certification process.
BIS certification is crucial for several reasons:
Market Access: It shall be marked with the ISI mark for it is compulsory for any manufacturer who wants their Rim Latches to be sold in India. This means that without this certification, manufacturers will not be able to sell their products to the market.
Consumer Safety: Certification means that the products have to conform to given standards in order to prevent the consumer from using dangerous products.
Quality Assurance: The BIS certification process helps ensure the quality standards of the products as it covers quality control aspects of the products.
Regulatory Compliance: The BIS certification acts as an asset to manufacturers since it avails them of the legal standards that are accepted by the government hence saving them from legal troubles.
Brand Credibility: An ISI mark adds value to the business by providing the consumers confidence that they are dealing with products that meet the nation’s quality standards.
Environmental Considerations: The BIS in its regulations has put forward specific measures to restrict the use of some dangerous chemicals when producing products that have to do with environmental effects in the industry.
The government-approved fees for BIS certification of molded solid rubber soles and heels under IS 1019:1974 are as follows:
| Category | Fee (INR) |
|---|---|
| BIS Application Fees | 9,000 |
NOTE: BIS marking and testing charge fees are subject to changes from time to time depending on the circulating governments’ policies on fee structure.
Thus, it is recommended to visit the official site of BIS or consult with a BIS registration consultant like Professional Utilities.
Conclusion
In conclusion, understanding IS 1019:1974 manufacturers who produce rim latches in India need to familiarise themselves. The standard not only prepares outlines critical performance requirements but also define a necessity of testing, labeling, documentary compliance for getting BIS certification. Thus, following these recommendations, manufacturers can guarantee that their products will be safe and conform to standard established for the market while consumers will trust product quality certified by recognized institutions.
