What is IS 13252(Part-1)?

Indian Standard IS 13252 is identical to IEC 60950-1: 2005 which includes specifications with respect to, “Information technology equipment — Safety — Part 1: General requirements.” This International Standard was adopted by the Bureau of Indian Standards (BIS) in accordance with the recommendations of the Computer Hardware, Peripherals, and Identification Cards Sectional Committee and the approval of the Electronics and Information Technology Division Council.

As mentioned, this standard is applicable to information technology equipment, whose demand is constantly increasing, It is clear from statistical data that the IT industry's revenue is expected to reach US$ 227 billion in FY22 from US$ 196 billion in FY21.

Though, it is to be noted that it is a mandatory requirement to meet the parameters of IS 13252, being experts we would advise you to meet the safety requirements provided in the standards as it will allow you to achieve a competitive advantage, including helping you in retaining customers. 

For a better understanding of why product testing is important, let’s have a look at why product testing is crucial.

Why is Product Testing Crucial | Importance of Product Testing

  • One of the most important purposes of testing is quality assurance of a product that reflects high quality, safety, and reliability.
  • Product testing allows the manufacturer to ensure conformance with established technical standards to produce high-quality and safe products.
  • Build reputation and maximize the profit, considering that a tested product indicates quality assurance. 
  • Helps in retaining customers, thus, providing a competitive edge.
  • Helps in understanding distinct types of stress a product can endure, be it in case of weather, wear tear, and other conditions.
  • In the initial prototyping stage, if you are trying to avail investment in order to manufacture your product in mass quantities, a tested product can allow you to achieve patent and investors as it shows the quality and functionality of the product.

With the benefits of product testing, we can clearly estimate how testing ensures quality assurance and product credibility.

Since it has been established how essential product testing is, now let’s move to the benefits of complying with standards.

What Are the Benefits of Complying With IS 13252?

Complying with standards offers numerous benefits to manufacturers and importers of the product, which further helps in building trustworthiness and reliability, thus retaining the customers.

Why, don’t we look at other benefits of the same -

  • A certified product acts as a shield against penalties and fines that could be imposed for not certifying a product.
  • A certified product serves as evidence that a product has been tested and certified as per prescribed standards.
  • A certified product provides a sense of security and safety to the consumers, thus ensuring easy acceptance.
  • It provides a competitive advantage over competitors.
  • Easy market acceptance as a product is tested and certified.
  • Confirm the unmatched quality standards.
  • Seamless to file government tenders.

With these benefits of ensuring conformance with IS 13252 standards and specifications, a manufacturer can establish that a product is safe, reliable, and credible, thus, confirming unmatched quality standards.

Scope of IS 13252 Part 1

IS 13252 Part 1 includes specifications with respect to the mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a rated voltage below 600 V. 

Along with that, below mentioned products also fall under its scope -

  • Products designed with the purpose to be used as telecommunication terminal equipment and telecommunication network infrastructure equipment.
  • Products that are designed and intended to be directly connected to or used as infrastructure equipment in a cable distribution system.
  • A product designed to use AC mains supply as a communication transmission medium. 

Test Requirements and Parameters Tested

1. Protection Against Hazardous Moving Parts

  1. General

The hazardous moving parts of equipment, which have the potential to cause injury should be arranged, enclosed, or guarded to minimize the risk of injury to an individual. 

  1. Protection in operator access areas

In this area, the protection should be provided through adequate construction to minimize the likelihood of access to hazardous moving parts or by locating the moving parts in an enclosure provided with mechanical or electrical safety interlocks which removes the hazardous when access is gained.

  1. Protection in restricted access locations

In this area, the protection will be provided in a way that unintentional contact with hazardous moving parts is unlikely during servicing operations involving other parts of the equipment. 

2. Direct Plug-in Equipment

It is a device that is intended to be used without any power supply cord and the main plug forms an integral part of the device enclosure in order to allow the socket outlet to take the weight of the equipment.

3. Limited Current Circuit

It is a circuit designed and protected under normal operating conditions and single fault conditions, while the current drawn is non-hazardous.

4. Components 

  1. Thermostat 

It is the cycling temperature sensing control intended to be used with the purpose of keeping the temperature between two particular values.

  1. Temperature limiter

It is also a temperature sensing control that is intended to keep the temperature high or low, one specific value during normal operating conditions.

  1. Thermal cut out

This temperature-sensing control is intended to operate under abnormal operating conditions and excludes any provision for the operator to change the temperature.

  1. Thermal cut or automatic reset

The thermal cut-out will automatically restore the current preceding the cooling down of the relevant part of the equipment.

  1. Interconnecting cables 

Interconnecting cables will be used for the below-mentioned reasons -

  • Electrically connect an accessory to the Information Technology equipment unit.
  • Interconnect unit in the system.
  • Connect a unit of telecommunication network or a cable distribution system.

5. Discharge of Capacitors in Equipment

The equipment should be designed in a way that at an operator-accessible external point of disconnection of a main supply, the risk shock from stored charge capacitors connected in the equipment will be minimized. 

6. Electrical Insulation

  1. Properties of insulating materials

The choice and application of insulating materials must be taken into account for the electrical, thermal, mechanical, and frequency of working voltage and working environment. Moreover, natural rubber, hygroscopic materials, and asbestos materials must not be used in the insulation. 

  1. Humidity conditioning

The humidity conditioning will be conducted for the duration of 48 hours in a cabinet or a room possessing air with a relative humidity between 91% to 95%. Moreover, the air temperature at all the places where the sample is placed must be maintained within 1 degree Celsius of any covenant value T between 20 degrees Celsius and 30 degrees Celsius.

  1. Grade of insulation

The grade of insulation used in this standard is functional insulation, basic insulation, supplementary insulation, reinforced insulation, or double insulation. 

7. Handles And Manual Controls

Handles, knobs, grips, levers, and other like should be adequately fixed in order to prevent their working in the loose in normal use, in case it creates a hazard. Also, it must indicate the position of switches or other similar components. 

8. Marking And Instructions

The marking and instructions are as follows -

9. Physical Requirements - Stability

Under conditions of normal use, the units and equipment must not become physically unstable to the degree to which they will become hazardous to an operator or service personnel. The below-mentioned test will be conducted to check the compliance -

  • Each test will be conducted separately.
  • During the test, the containers contain the substances within their prescribed rated capacity producing the most disadvantageous condition.
  • In the case of using castors and jacks in normal operating conditions, it must be placed in the most unfavorable condition with the wheels and likes blocked and locked.
