Scheme X Certification is a conformity assessment system established by the Bureau of Indian Standards (BIS) to ensure that specific products meet designated Indian Standards. This scheme is particularly focused on low-voltage switchgear and control gear products, including circuit breakers, switches, motor starters, proximity switches, and emergency stop devices. Manufacturers of these products are required to obtain BIS certification and use the Standard Mark to demonstrate compliance. Non-compliance can result in penalties under the BIS Act, 2016.
The Scope of Scheme X Certification under the Bureau of Indian Standards (BIS) refers to the specific categories of products and the regulatory framework they must comply with to ensure safety, quality, and standardization. Here’s a breakdown of the scope:
| Aspect | Scheme-I (ISI Mark Scheme) | Scheme-X (Controlgear Scheme) |
|---|---|---|
| Purpose | For general consumer and industrial goods to ensure ongoing compliance with Indian Standards. |
Specifically designed for low-voltage switchgear and controlgear products under Schedule-II of BIS Regulations. |
| Products Covered | Wide range of products (steel, cement, kitchen appliances, etc.). | Select electrical and electronic items like circuit breakers, switches, proximity sensors, etc. |
| Standard Mark | ISI Mark (Indian Standards Institute) | BIS Standard Mark with Scheme-X identifier |
| Type of Testing | Testing is done in BIS-approved labs before and after licensing. | Emphasis on witness testing and in-house testing facilities, including subcontracted facilities. |
| Surveillance | Regular factory surveillance and market samples. | Includes more stringent audit and testing requirements specific to controlgear. |
| Applicability | Used for both voluntary and mandatory certification. | Applies primarily to mandatory certification categories under Scheme-X. |
| Foreign Manufacturer Process | Covered under the FMCS (Foreign Manufacturers Certification Scheme) for ISI mark. |
Foreign manufacturers must also comply, with special provisions for Scheme-X-specific audits. |
| Compliance Basis | BIS (Conformity Assessment) Regulations, 2018 – Scheme-I | BIS (Conformity Assessment) Regulations, 2018 – Scheme-X of Schedule-II |
