Different institutes and organizations have established different standards for mild steel. Every nation has its own standards, which are set by relevant authorities. The most widely used worldwide standards that guarantee dependability, quality, and safety are ASTM, IS, and EN. To assist you in making an informed choice for your project, we have explained the distinctions between ASTM, IS, and EN standards for mild steel in this blog.

ASTM Mild Steel Standards

Technical standards for materials are established by the internationally renowned American Society for Testing Materials, or ASTM International. For mild steel and hot-rolled steel, ASTM A36 is frequently utilized. These steel standards are used for a variety of mild steel grades in shapes including angles, I-beams, and H-beams, as well as in diverse forms like MS round bars, MS square bars, and MS rectangular bars.

ASTM International (previously the American Society for Testing and Materials) is a strong organization that is behind enigmatic acronyms like "ASTM B194".

They are the world leader in developing voluntary standards for materials such as paints, metals, and polymers, guaranteeing reliable and consistent performance. Consider them the material properties' translators, developing a global language that specifies the best qualities and testing procedures for an infinite number of materials.

More than 30,000 enthusiastic volunteers from more than 140 nations, including government organizations, scientists, engineers, and architects, are behind this endeavor. They work together to establish the standards for different materials, guaranteeing that you always receive precisely what you anticipate.

How are safety standards created by ASTM?

It takes time for these standards to emerge. Everyone is guaranteed a voice through this methodical, transparent procedure. A new standard can be proposed by any interested party, including solitary academics or industry titans. The idea is next examined by a specialized technical committee, which refines it through several review and feedback phases .
Consider it a rigorous peer-review process for your metal mixology expertise. Before the standard makes it to the last step, which is acceptance by the ASTM International Committee on Standards, every objection or concern is thoroughly examined. Fairness, balance, and a standard that accurately represents the requirements of each industry are ensured by this approach.

ASTM Safety Standards: Why Are They Important?

Consider creating a delicate piece of jewelry or constructing a bridge. The caliber and reliability of your supplies will determine how well your project turns out. ASTM safety standards serve as a reliable roadmap through the material tangle in this situation.

IS Mild Steel Standards

The physical specifications for mild steel are outlined in the Indian Standards (IS). The IS 2026 Grade A and Grade B mild steel grades are the most widely accessible. production requirements, defect-free production, nominal sizes and masses, tolerances, physical criteria, and testing are all mentioned in the IS standards.

The Bureau of Indian Standards (BIS) establishes the ISI Indian Standard as the safety and quality benchmark for goods manufactured, imported, or marketed in India. The Indian Standards Institute, or "ISI," was the initial name of the organization that is currently known as BIS.

Each product covered by ISI Indian Standards needs to adhere to a particular IS code, such as IS 1476 for refrigerators, IS 2347 for pressure cookers, and IS 302 for electric irons.
The ISI Mark is applied to products that comply with the Indian Standard, guaranteeing both public trust and regulatory compliance.

Mumbai Customs detained the shipment of ceiling fans that a Chinese manufacturer was exporting under a private label to an Indian e-commerce site in 2023. Why? Under IS 374:2019, there is no ISI Mark. They lost ₹18 lakh in storage fees as a result of having to airfreight samples back, repeat testing, and apply for BIS.

The ISI Mark: What is it?

A conformance mark known as the ISI Mark attests to a product's compliance with the relevant Indian Standard (IS Code). It consists of:

The standard number (e.g., IS 4151 for helmets)
The BIS license number
The BIS logo

It is against the law to sell regulated goods in India without this mark.

A government drill machine supply deal worth ₹12 crore was lost by a German power tool firm because their product was not ISI certified under IS 7558. The tender required ISI despite worldwide ISO certifications, demonstrating that national regulations can take precedence over global norms.

Why is the ISI Indian Standard required in India?

Within India's Ministry of Consumer Affairs, the Bureau of Indian Standards (BIS) is the organization responsible for certifying that products meet national standards for performance, safety, and dependability. The technical specification is the ISI Indian Standard, and the conformance is confirmed by the BIS Certificate.

Principal Goals:

Keep inferior imports away from Indian customers.
Avoid untested items and counterfeits.
Promote high-quality Indian production
Tighten trade laws under QCOs and Made in India

EN Mild Steel Standards

EN (European Standards) standards are met by mild steel. Mechanical properties including tensile strength , corrosion resistance , ductility , weldability , and forging are highly valued in the EN standards.

A regulated procedure known as EN certification guarantees that goods and services fulfill strict safety, performance, and quality standards established by the European Union (EU). This globally recognized certification shows that a product or service has passed stringent testing and satisfies all requirements to be marketed in the EU market. We shall examine the significance of EN certification and how it affects different industries in this post.

The advantages of being certified by EN

1. Compliance with EU rules: The guarantee that the good or service conforms with EU regulations is one of the main advantages of EN certification. Consumer protection and the availability of safe and useful items on the EU market are the goals of these rules.

2. Increased product credibility: A product or service's credibility can be greatly increased by obtaining EN certification. Customers are reassured that the product has undergone extensive testing and satisfies strict quality standards.

3. Greater market accessibility: Businesses with EN certification can get into the enormous EU market, which has over 450 million customers. This creates fresh chances for development and growth.

4. Competitive advantage: Businesses who possess EN certification may have an advantage over those that do not. It can draw in new clients and partners by showcasing the business's dedication to quality and compliance.

5. Risk reduction: EN certification aids in lowering risks related to the safety and quality of products. Businesses can prevent potential issues, legal action, and harm to their brand from defective or dangerous items by following stringent guidelines.

The EN certification process

A number of procedures are included in the EN certification process to guarantee adherence to pertinent standards. The crucial phases are as follows:

1. Application: The business must first submit an application to the relevant certifying authority. They must give comprehensive details about their service or product, including testing protocols, specs, and any current certifications.

2. Testing: The product or service is put through extensive testing to determine whether it complies with EN requirements after the application is approved. Performance reviews, safety evaluations, and quality checks are a few examples of these tests.

3. Documentation review: The certification body thoroughly examines all product or service-related documentation to ensure that it satisfies all standards. Examining test results, technical information, and manufacturing procedures are all part of this.

4. Certification issuance: An EN certificate is issued by the certification organization if the product or service passes all tests and evaluations. This certificate serves as evidence of conformity and is often valid for a specific amount of time, after which it might be necessary to recertify.

5. Continuous monitoring: Businesses must submit to recurring audits and inspections to guarantee continuous compliance in order to keep their EN certification. This ongoing oversight guarantees that approved goods and services constantly meet the necessary requirements.
