BIS Certification for Ear Protectors | IS 9167:1979 | ISI Mark

Introduction

Ear Protectors are important personal protective equipment designed to reduce exposure to high noise levels and help protect hearing in industrial and occupational environments. Common products covered by IS 9167:1979 include permanent or disposable ear-plugs, ear-muffs and helmets incorporating hearing protection.

The Bureau of Indian Standards (BIS) has published a Product Manual for Ear Protectors according to IS 9167:1979 under Scheme-I of the BIS Conformity Assessment Regulations, covering the use of the BIS Standard Mark, commonly known as the ISI Mark. The Product Manual specifies requirements relating to sampling, product grouping, testing facilities, factory testing, inspection and the Scheme of Inspection and Testing.

For manufacturers planning BIS certification for hearing protection products, it is important to understand the applicable product type, testing requirements, manufacturing controls, documentation and the scope that can be included in the BIS licence.

What is BIS Certification for Ear Protectors?

BIS Certification for Ear Protectors is the process through which a manufacturer demonstrates that its ear protection products conform to the requirements of IS 9167:1979 – Specification for Ear Protectors and obtains a BIS licence to use the Standard Mark.

The official BIS Product Manual identifies the certification route as Scheme-I, under which BIS assesses the manufacturer's manufacturing infrastructure, production process, quality-control system and testing capabilities and establishes product conformity through the applicable testing arrangements.

Once the licence is granted, conforming production covered by the licence can be marked with the applicable BIS Standard Mark according to the conditions of the licence.

BIS Standard for Ear Protectors

The applicable Indian Standard is:

IS 9167:1979 – Specification for Ear Protectors

According to the current BIS Product Manual:

Product: Ear Protectors
Standard: IS 9167:1979
Number of amendments: 1
Certification scheme: Scheme-I
Sample size: 10 units
Raw-material sampling: Not applicable
Grouping: As specified in Annex A of the Product Manual

BIS's current product-specific information continues to list IS 9167:1979 – Ear Protectors among its product manuals.

Types of Ear Protectors Covered Under IS 9167:1979

The BIS Product Manual identifies three principal types:

1. Ear-Plugs

Ear-plugs may be:

Permanent
Disposable

2. Ear-Muffs

Ear-muffs are externally worn hearing-protection devices designed to cover the ears and reduce exposure to excessive noise.

3. Helmets

The standard's licence scope also includes helmets incorporating ear protection.

Manufacturers should clearly identify the type or types they intend to include in their BIS licence.

Important Grouping Guidelines for Ear Protectors

Grouping is particularly important while applying for BIS Certification.

The official BIS Product Manual states that each of the three principal categories—ear-plugs, ear-muffs and helmets—is to be tested separately for the purpose of Grant of Licence and Continued Surveillance of Licence.

However, there is an important provision:

When permanent ear-plugs are tested, disposable ear-plugs may also be covered in the licence scope.

The manufacturer must declare the varieties of Ear Protectors proposed to be included in the licence.

BIS may restrict the licence scope according to the manufacturer's:

Manufacturing capability
Testing facilities
Product varieties
Demonstrated conformity

The Product Manual also states that, during the operation of the licence, the BIS Branch Office should ensure that the varieties included in the licence are tested in rotation to the extent possible.

BIS Certification Process for Ear Protectors

The BIS certification process for Ear Protectors involves several technical and administrative stages.

Step 1 – Identify the Product Type

First, identify whether the product is:

Permanent ear-plug
Disposable ear-plug
Ear-muff
Helmet with ear protection

This is important because product grouping and testing are based on the type of ear protector.

Step 2 – Review IS 9167:1979 Requirements

The manufacturer should review:

Materials
Construction
Workmanship
Environmental durability
Sound attenuation
Marking
Maintenance requirements
Factory testing facilities

Step 3 – Assess Manufacturing Facilities

BIS Scheme-I certification requires assessment of the manufacturer's manufacturing infrastructure, production process, quality-control arrangements and testing capabilities.

Step 4 – Prepare Required Testing Facilities

Because the Product Manual specifies factory-based testing for this product, the manufacturer needs suitable testing facilities and equipment at the manufacturing premises for the applicable tests.

Step 5 – Submit BIS Application

The manufacturer submits the BIS application through the prescribed online process.

BIS states that Scheme-I applications are submitted online and require the relevant information and documents prescribed for the application.

Step 6 – Factory Inspection

BIS assesses the manufacturing facilities, production process, quality control and testing capability through a visit to the manufacturing premises.

Step 7 – Sample and Testing

The applicable product samples are assessed according to IS 9167:1979 and the Product Manual.

The Product Manual specifies a sample size of 10 units and states that complete testing is carried out in the factory, with 4 days required for complete testing under the stated factory-testing basis.

Step 8 – Resolve Non-Conformities

If any deficiency or non-conformity is identified, the manufacturer must take corrective action and demonstrate conformity as required by BIS.

Step 9 – Grant of BIS Licence

Once the manufacturing facilities and product conformity are satisfactorily established, BIS can grant the licence for use of the Standard Mark within the approved scope.

Sampling Requirements for Ear Protectors

According to the official Product Manual:

Inspection records
Test records
Packaging
Dispatch documentation

BIS Standard Mark / ISI Mark for Ear Protectors

Once the BIS licence is granted, production covered under the licence and conforming to the applicable Indian Standard should be marked with the BIS Standard Mark as permitted by the licence.

The Product Manual states:

All production conforming to the Indian Standard and covered by the licence should be marked with the Standard Mark.

The exact form, size, placement and accompanying licence information should follow the conditions of the BIS licence and applicable marking requirements.

Scope of BIS Licence for Ear Protectors

The BIS Product Manual provides the following product scope:

Product: Ear Protectors

Types:

Ear-plugs – permanent/disposable
Ear-muffs
Helmets

The manufacturer should declare the varieties intended to be covered.

BIS may restrict the scope based on manufacturing capabilities and available testing facilities.

Can Permanent and Disposable Ear-Plugs Be Covered Together?

The BIS Product Manual provides a specific grouping provision.

Where permanent ear-plugs are tested, disposable ear-plugs may also be covered within the licence scope.

However, ear-muffs and helmets remain separately tested product types under the grouping requirements.

Can Ear-Muffs and Ear-Plugs Be Covered Under the Same Testing?

The grouping guidelines state that each type—ear-plugs, ear-muffs and helmets—shall be tested separately for Grant of Licence and Continued Surveillance purposes.

Therefore, manufacturers should not assume that testing one category automatically establishes conformity for the other categories.

BIS Factory Inspection for Ear Protectors

BIS Scheme-I certification involves assessment of the manufacturing premises.

The Bureau assesses:

Manufacturing infrastructure
Production process
Quality-control system
Testing capability
Product conformity

through a factory visit.

For Ear Protectors, this is particularly important because the Product Manual specifies factory-based complete testing.

Documents Required for BIS Certification

BIS application guidance identifies documents such as firm/factory address proof, legal identity, manufacturing process flow chart, location plan, layout plan, quality-control personnel qualification documents, raw-material/test documents and calibration certificates as part of the application documentation, as applicable to the product and application.

Testing Equipment Calibration

Calibration is an important part of maintaining the factory testing system.

The BIS Product Manual requires the manufacturer to prepare a calibration plan for testing equipment and maintain suitable records.

Manufacturers should ensure that:

Test instruments are calibrated
Calibration certificates are current
Equipment identification is maintained
Test results are traceable to equipment
Calibration records are properly maintained

BIS Certification Fees for Ear Protectors

The overall cost of BIS Certification under Scheme-I normally contains different components rather than a single fixed amount.

BIS's current certification FAQ lists:

Application Fee: ₹1,000

Inspection Fee: ₹7,000 per man-day

After the decision to grant the licence, the applicant is required to pay the applicable annual licence fee and the minimum marking fee specified for the product.

For Ear Protectors, the actual total project cost depends on:

Factory inspection requirements
Number of inspection man-days
Testing arrangements
Calibration requirements
Minimum marking fee
Annual licence fee
Consultancy charges
Applicable taxes

Therefore, a fixed all-inclusive amount should not be assumed without checking the current BIS fee schedule and product-specific marking-fee provisions.

BIS Certification Timeline for Ear Protectors

BIS's current FAQ states that the average time for grant of a BIS licence is generally:

About one month under Option 2
About four months under Option 1

from receipt of a complete application and its recording, subject to factors such as queries, inspection arrangements, sample deposition and fee payments.

For Ear Protectors, the actual project timeline may depend on the applicable factory-testing process, readiness of testing equipment, factory inspection, correction of deficiencies and completion of conformity assessment.

BIS Licence Validity for Ear Protectors

BIS's current Scheme-I FAQ states that certification may initially be granted for up to two years and that the licence may subsequently be renewed for periods up to five years from the last date of validity, subject to the applicable renewal requirements.

Manufacturers should monitor the licence validity date and submit renewal applications with the required production information, fees and documents.

BIS Surveillance After Certification

Obtaining a BIS licence does not end the manufacturer's compliance responsibilities.

BIS carries out surveillance activities after grant of licence.

According to BIS, factory surveillance can include:

Factory visits
Verification of manufacturing infrastructure
Verification of quality-control and testing capabilities
Witnessing testing
Drawing product samples
Third-party laboratory testing
Market surveillance

For Ear Protectors, maintaining regular factory testing records and product traceability is therefore important throughout the licence period.
