Introduction

Tumbler dryers are electrical appliances used for drying clothes through a combination of heat and mechanical tumbling. Since these appliances involve electrical components, heating systems, motors and control mechanisms, their safety and performance need to meet applicable Indian Standards.

For manufacturers and importers planning to supply tumbler dryers in India, understanding the applicable BIS requirements is important. The product-specific Indian Standard is IS 302 (Part 2/Sec 11):1994 – Safety of Household and Similar Electrical Appliances – Particular Requirements for Tumbler Dryers. The requirements of the particular standard are applied along with the relevant general safety requirements of the IS 302 series.

The BIS Product Manual for Tumbler Dryers provides important information regarding the certification process, sampling, testing, inspection and other requirements applicable to the product.

What is BIS Certification for Tumbler Dryers?

BIS Certification for Tumbler Dryers is the conformity assessment process through which a manufacturer demonstrates that its product complies with the applicable Indian Standard and BIS requirements.

For products covered under the applicable compulsory certification framework, the manufacturer needs to obtain the required BIS licence before manufacturing or selling the product in the Indian market.

Tumbler dryers are covered under the relevant electrical-appliance safety framework. The applicable product requirements are based on IS 302-2-11:1994, together with the relevant general requirements of the IS 302 series.

Once the manufacturer successfully completes the applicable BIS conformity assessment requirements and obtains the licence, the product can be marked according to the conditions of the BIS licence.

Applicable Indian Standard for Tumbler Dryers

The main product-specific standard is:

IS 302 (Part 2/Sec 11):1994 – Particular Requirements for Tumbler Dryers

This standard addresses safety requirements applicable to tumbler dryers. It should be read along with the applicable general requirements of the IS 302 series.

The standard is intended to address safety aspects associated with electrical operation, heating, mechanical operation, construction and other relevant characteristics of the appliance.

Manufacturers should always verify the latest applicable standard, amendments and BIS requirements before starting the certification process.

BIS Certification Process for Tumbler Dryers

Obtaining certification involves several stages. A typical process can be structured as follows:

Step 1: Identify the Applicable Standard

The first step is to determine the correct Indian Standard applicable to the tumbler dryer.

The product configuration, operating characteristics and intended application should be reviewed to confirm the applicable requirements under IS 302-2-11:1994 and the relevant general requirements.

Step 2: Review Product and Technical Details

The manufacturer needs to provide complete information about the product, including its construction, electrical ratings, models, components and manufacturing details.

This information is reviewed to determine the appropriate certification scope and testing requirements.

Step 3: Prepare BIS Documentation

The required technical and manufacturing documents are prepared for the BIS application.

Depending on the application and applicable requirements, documentation may include:

• Manufacturer details

• Factory address and manufacturing information

• Product specifications

• Technical drawings

• Circuit diagrams

• Bill of materials

• Details of critical components

• Product labels and marking details

• Test reports, where applicable

• Manufacturing process information

• Details of testing facilities

• Quality-control arrangements

Step 4: Product Testing

One of the most important stages is product testing.

The tumbler dryer is tested against the applicable requirements of the relevant Indian Standard at a BIS-recognized or otherwise applicable laboratory/facility, as required by the conformity assessment procedure.

The BIS Testing Requirement for Tumbler Dryers may cover relevant safety characteristics specified under the standard. Testing should be performed according to the applicable clauses and current BIS requirements.

Step 5: Factory Inspection

Where required under the applicable BIS conformity assessment procedure, BIS officials assess the manufacturing premises.

The assessment may include examination of:

• Manufacturing facilities

• Quality-control arrangements

• Testing equipment

• Production process

• Inspection procedures

• Raw materials and components

• Product identification and traceability

The manufacturer should have the required infrastructure and quality-control system available before the assessment.

Step 6: Submission and Evaluation of Application

After completing the required testing and documentation, the BIS application and supporting information are evaluated according to the applicable certification procedure.

If any clarification, additional information or corrective action is required, the applicant needs to address it before the process can proceed.

Step 7: Grant of BIS Licence

After successful completion of the applicable evaluation and conformity requirements, BIS may grant the licence to the manufacturer.

The manufacturer can then use the BIS ISI Mark for Tumbler Dryers in accordance with the conditions and marking requirements associated with the licence.

BIS Registration for Tumbler Dryers

The term BIS Registration for Tumbler Dryers is sometimes used generally for regulatory approval. However, manufacturers should identify the exact BIS conformity assessment route applicable to their product.

Tumbler dryers are associated with the BIS product certification framework for the applicable Indian Standard rather than being treated as a typical CRS registration product.

Therefore, applicants should not assume that every electrical product requires the same BIS registration procedure. The applicable QCO, Indian Standard and BIS conformity assessment requirements should be checked before applying.

BIS ISI Mark for Tumbler Dryers

The BIS Standard Mark, commonly known as the ISI Mark, indicates that the certified product is covered by a valid BIS licence and complies with the applicable requirements within the approved scope.

After obtaining the relevant BIS licence, the manufacturer must follow the prescribed marking requirements. The ISI Mark should not be used merely because an application has been submitted or a product has been tested.

The marking, licence number and other required information should be provided according to the applicable BIS rules and licence conditions.

BIS Testing Requirements for Tumbler Dryers

Testing is a critical part of the certification process. The BIS Testing Requirement for Tumbler Dryers is based on the applicable requirements of IS 302-2-11:1994 and the relevant general requirements.

Testing may examine safety characteristics associated with the construction and operation of the appliance.

Manufacturers should ensure that the product submitted for testing is representative of the model or range covered by the application. Any significant change in design, components, ratings or construction may need to be evaluated for its effect on certification.

The current BIS Product Manual should be referred to for the applicable sampling, testing and inspection requirements.

BIS Product Manual for Tumbler Dryers

The BIS Product Manual for Tumbler Dryers is an important reference document for manufacturers.

It provides information related to the implementation of IS 302-2-11:1994, including aspects such as:

• Product scope

• Sampling requirements

• Grouping of products

• Test equipment

• Inspection and testing requirements

• Raw materials and components

• Scheme of Inspection and Testing

• Certification and surveillance-related requirements

Manufacturers should study the Product Manual before beginning the certification process because it helps them understand the practical requirements associated with the applicable standard.
