Introduction
One of the oxygen electric nationalizing element factory manufacturer in Pune civilian a heating elements based on component idea loss of the resistance side of the wire consecutively series of IS 12045:1987 steps by the most important OEM spontaneously that took them the contract never the Quality of their production stayed the same but now the buyer accepted only materials that are BIS-approved to avoid variation in resistivity and long-term heat stability. Similar changes are happening everywhere in the range of appliance brands, industrial heater suppliers, and furnace manufacturers. As quality control orders tighten, uncertified Alloys Used in Electrical are increasingly being pointed out during vendor audits. Bureau of Indian Standards
What is IS 12045:1987?
IS 12045:1987 is an India Standard that outlines the technical requirements of the alloys that are used in electrical resistance metallic heating elements. It details the attributes of the alloy when exposed to high temperatures, repeated heating cycles and extended periods of service. The standard is aimed at ensuring that the material exhibits electrical resistivity that is predictable, mechanical properties that are stable, and oxidation behaviour that is reliable- these being the factors that are the most important for the safe and trouble-free function of the heating elements.
Key points:
- Covers resistance alloys such as Ni-Cr and Fe-Cr-Al in wire, strip, and ribbon form
- Defines limits for chemical composition, resistivity, and temperature coefficient of resistance
- Specifies mechanical properties such as tensile strength and elongation
- Includes provisions for oxidation resistance and thermal stability over long periods of time
- Forms the technical basis for BIS Certification for heating element alloys in India. ISI MARK
Why is BIS Certification Mandatory
BIS Certification is mandatory for that part of the metal base used for making electrical heating elements, i.e., resistance alloys covered by IS 12045:1987. These are the materials that have a direct impact on the safety, the life span, and the performance of the heating elements and thus, have to be of the highest quality. In case the main alloy is not uniform, a small change in the resistivity or the composition can result in a situation where the element will overheat, break down within a very short time, or an electrical hazard will occur.
Key reasons why it is mandatory:
- Ensures uniform resistivity and high-temperature performance across all batches
- Prevents substandard or unsafe alloys from entering industrial and consumer supply chains
- Aligns Indian manufacturers with quality benchmarks demanded by major appliance and industrial OEMs
- Supports traceability and accountability through periodic audits and surveillance
- Strengthens domestic industry standards while reducing dependency on uncertified imports
Importance and Benefits of BIS Certification
| Importance | Benefits |
| Ensures alloys meet defined safety and performance standards | Improves product reliability and reduces failure rates |
| Prevents uncertified or low-quality materials from entering the market | Enhances customer trust and acceptance by major OEMs |
| Supports regulatory compliance under mandatory Quality Control Orders | Enables participation in government tenders and regulated sectors |
| Maintains consistency in resistivity, composition, and thermal behaviour | Provides pricing leverage due to verified quality |
| Strengthens manufacturing discipline through audits and traceability | Boosts export credibility and eases global approvals |

Conclusion
Today, producers of resistance alloys are facing a market where supply of safe, consistent and traceable products is the main condition for seller’s eligibility. Obtaining BIS Certification for Alloys Used in Electrical Resistance Metallic Heating Elements IS 12045:1987 is a step towards confirming that every batch is in line with the technical requirements of OEMs, standardization bodies and export clients. It diminishes the chances of failures, makes vendor qualification easier and increases the company’s market credibility over time. Early compliance turned out to be a real leverage for businesses willing to grow or enter regulated sectors.
Frequently Ask Questions
What Is IS 12045:1987?
This standard is an Indian standard, which describes the technical conditions of the electrically resistant alloys that are used for metallic heating elements.
Why Must BIS Certification Be Done for Resistance Alloys?
As the safety, performance, and quality of the heating elements that are most important, and are directly related to these alloys, it is only logical that certification be mandatory in compliance with Government Quality Control Orders.
Which Materials Are Under IS 12045:1987?
Nickel-chromium, iron-chromium-aluminum, and other resistance alloys in rod, wire, strip, and ribbon forms.
Who Needs To Get BIS Certification Under This Standard?
Manufacturers, importers, and OEM suppliers of resistance heating element alloys, who are engaged in related activities, need BIS certification.
