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<\/strong> include permanent or disposable ear-plugs, ear-muffs and helmets incorporating hearing protection<\/strong>.<\/p>\n

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

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.<\/p>\n

\n
\n<\/div>\n
What is BIS Certification for Ear Protectors?<\/h1>\n
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 \u2013 Specification for Ear Protectors<\/strong> and obtains a BIS licence to use the Standard Mark.<\/p>\n
The official BIS Product Manual identifies the certification route as Scheme-I<\/strong>, 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.<\/p>\n
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.<\/p>\n
\n
\n<\/div>\n

BIS’s current product-specific information continues to list IS 9167:1979 \u2013 Ear Protectors<\/strong> among its product manuals.<\/p>\n
\n
\n<\/div>\n
Types of Ear Protectors Covered Under IS 9167:1979<\/h1>\n
The BIS Product Manual identifies three principal types:<\/p>\n
1. Ear-Plugs<\/h3>\n
Ear-plugs may be:<\/p>\n
\n
Permanent<\/li>\n
Disposable<\/li>\n<\/ul>\n
2. Ear-Muffs<\/h3>\n
Ear-muffs are externally worn hearing-protection devices designed to cover the ears and reduce exposure to excessive noise.<\/p>\n
3. Helmets<\/h3>\n
The standard’s licence scope also includes helmets incorporating ear protection.<\/p>\n
Manufacturers should clearly identify the type or types they intend to include in their BIS licence.<\/p>\n
\n
\n<\/div>\n
Important Grouping Guidelines for Ear Protectors<\/h1>\n
Grouping is particularly important while applying for BIS Certification.<\/p>\n
The official BIS Product Manual states that each of the three principal categories\u2014ear-plugs, ear-muffs and helmets\u2014is to be tested separately<\/strong> for the purpose of Grant of Licence and Continued Surveillance of Licence.<\/p>\n
However, there is an important provision:<\/p>\n
When permanent ear-plugs are tested, disposable ear-plugs may also be covered in the licence scope.<\/strong><\/p>\n
The manufacturer must declare the varieties of Ear Protectors proposed to be included in the licence.<\/p>\n
BIS may restrict the licence scope according to the manufacturer’s:<\/p>\n
\n
Manufacturing capability<\/li>\n
Testing facilities<\/li>\n
Product varieties<\/li>\n
Demonstrated conformity<\/li>\n<\/ul>\n
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.<\/p>\n
\n
\n<\/div>\n
BIS Certification Process for Ear Protectors<\/h1>\n
The BIS certification process for Ear Protectors involves several technical and administrative stages.<\/p>\n
Step 1 \u2013 Identify the Product Type<\/h2>\n
First, identify whether the product is:<\/p>\n
\n
Permanent ear-plug<\/li>\n
Disposable ear-plug<\/li>\n
Ear-muff<\/li>\n
Helmet with ear protection<\/li>\n<\/ul>\n
This is important because product grouping and testing are based on the type of ear protector.<\/p>\n
Step 2 \u2013 Review IS 9167:1979 Requirements<\/h2>\n
The manufacturer should review:<\/p>\n
\n
Materials<\/li>\n
Construction<\/li>\n
Workmanship<\/li>\n
Environmental durability<\/li>\n
Sound attenuation<\/li>\n
Marking<\/li>\n
Maintenance requirements<\/li>\n
Factory testing facilities<\/li>\n<\/ul>\n
Step 3 \u2013 Assess Manufacturing Facilities<\/h2>\n
BIS Scheme-I certification requires assessment of the manufacturer’s manufacturing infrastructure, production process, quality-control arrangements and testing capabilities.<\/p>\n
Step 4 \u2013 Prepare Required Testing Facilities<\/h2>\n
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.<\/p>\n
Step 5 \u2013 Submit BIS Application<\/h2>\n
The manufacturer submits the BIS application through the prescribed online process.<\/p>\n
BIS states that Scheme-I applications are submitted online and require the relevant information and documents prescribed for the application.<\/p>\n
Step 6 \u2013 Factory Inspection<\/h2>\n
BIS assesses the manufacturing facilities, production process, quality control and testing capability through a visit to the manufacturing premises.<\/p>\n
Step 7 \u2013 Sample and Testing<\/h2>\n
The applicable product samples are assessed according to IS 9167:1979 and the Product Manual.<\/p>\n
The Product Manual specifies a sample size of 10 units<\/strong> and states that complete testing is carried out in the factory, with 4 days required for complete testing<\/strong> under the stated factory-testing basis.<\/p>\n
Step 8 \u2013 Resolve Non-Conformities<\/h2>\n
If any deficiency or non-conformity is identified, the manufacturer must take corrective action and demonstrate conformity as required by BIS.<\/p>\n
Step 9 \u2013 Grant of BIS Licence<\/h2>\n
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.<\/p>\n
\n

\n
\n<\/div>\n
Can Permanent and Disposable Ear-Plugs Be Covered Together?<\/h1>\n
The BIS Product Manual provides a specific grouping provision.<\/p>\n
Where permanent ear-plugs are tested<\/strong>, disposable ear-plugs may also be covered within the licence scope.<\/p>\n
However, ear-muffs and helmets remain separately tested product types under the grouping requirements.<\/p>\n
\n
\n<\/div>\n
Can Ear-Muffs and Ear-Plugs Be Covered Under the Same Testing?<\/h1>\n
The grouping guidelines state that each type\u2014ear-plugs, ear-muffs and helmets\u2014shall be tested separately for Grant of Licence and Continued Surveillance purposes.<\/p>\n
Therefore, manufacturers should not assume that testing one category automatically establishes conformity for the other categories.<\/p>\n
\n
\n<\/div>\n
BIS Factory Inspection for Ear Protectors<\/h1>\n
BIS Scheme-I certification involves assessment of the manufacturing premises.<\/p>\n
The Bureau assesses:<\/p>\n

Is BIS Certification for Ear Protectors Mandatory?<\/h1>\n
The official BIS Product Manual confirms that IS 9167:1979 is handled under Scheme-I certification for use of the BIS Standard Mark<\/strong>.<\/p>\n
Whether BIS certification is compulsory for a particular supply, industry, procurement specification or end-use should be checked against the applicable government notification, regulatory requirement or purchasing specification. The sources reviewed for this article confirm the Scheme-I certification route but do not by themselves establish a universal current QCO making IS 9167:1979 compulsory for every manufacturer.<\/p>\n
This distinction is important because BIS certification under Scheme-I and compulsory certification under a separate regulatory order are not the same question<\/strong>.<\/p>\n
