In many countries, professional engineers are called Chartered Engineers. The details of registration vary from country to country. In The Republic of India, a chartered engineer is a corporate member of the Institution of Engineers (India).

Chartered Engineers are usually degree-qualified and have spent at least five years in professional practice.

We provide the chartered engineering services in new projects like valuation of plant & machinery, Energy Audit etc..

As a qualified Professionals and Independent Chartered Engineers, we have specialised in the field of issuing certificates as required by companies in the Export - Import and License work.

Some of the applications include certification of advance license Application, EPCG Licence Application, Duty Drawback Statements, Consumption Certificates, Utilisation Certificates, Wastage Certificates, Manufacturing Process Certificates, Certificates required by Customs, Banks and Financial Institutions.

The Technical Report is a common written form us, which communicate our findings for a given project. Each Technical Report should have a focused topic that is developed logically along some clearly identified perspective.

The major components of a Technical Report are title, author information, informative abstract, body, acknowledgments, references, keywords, and appendices. Typically, the body is organized into four sections: motivation, methods, results, and discussion. This document offers advice and specifications for projects.

Mihir Enterprises is the service provider of Consultancy and Technical Report for future development work of a Project. This service includes project reports, viability reports etc.

We have done various studies like Viability Study Report, Depreciation Study Report and Techno-economical Study Report etc.

While making a technical report we consider different parameters like Construction Policies, Government Policies and Support, Financial Structure, Infrastructure Management, Time Management, Manpower Management and all other related parametric quantity

Product Approvals Ltd is a consulting engineering practice specialising in helping electronics companies with obtaining product safety approvals, for example CE marking for the European market and nationally recognised testing laboratory (NRTL) marking for the North American market using third-party agencies such as Underwriters Laboratories (UL). Here are some further benefits to you of using my services:

• Completely impartial advice aimed at helping you fulfill your specific product approvals requirement.
• An in depth understanding of the unique requirements for electronic products
• An emphasis on tailoring a solution to your unique needs.
• A hands-on approach if that's what you need.
• Over 15 years experience in obtaining UL approval
• Knowledge of standards including UL 508C Power conversion equipment, UL 840 Insulation co-ordination, UL 50 Enclosures for electrical equipment, UL 746 Polymeric material use in electrical equipment, UL 1449 Transient voltage surge suppressors, EN 61800-5-1 Electrical power drive systems, EN 50178 Electronic equipment for use in power installations, EN 60529 IP codes, NEMA-250 Enclosures for electrical equipment, Canadian standard CSA C22.2 No. 14 Industrial Control Equipment etc.
• Determination of optimal product certification routes.
• Additional flexible resource as and when you need it.
• A means of staying up-to-date with current legislation affecting electronics equipment.
• Design reviews - on site - or by web conferencing.
• Custom-written design guidelines

The service will be tailored to best suit your unique requirements.

1. Preliminary safety design reviews. To help ensure conceptual designs are compliant with key safety requirements from the outset of the project.
   • Service code PSDR1 (on-site)
   • Service code PSDR2 (web based)
2. Project management and facilitation of third-party safety approval submittals e.g. obtaining agency listings for US and Canadian markets.
   • Service code TPSA
3. Assistance with self-certification CE-marking of products to the Low Voltage Directive for the EU market.
   • Service code SCA-LVD
4. Creation and implementation of complete product design verification plans to address product conformity aspects including safety, EMC, environmental (climatic, vibration), user-interface, integrity and reliability aspects as required.
   • Service code PDVP
5. Review of market entry product approval options. For example investigation of alternate certification agency routes and product label markings.
   • Service code ME
6. Legislation monitoring. This could for example involve monitoring of a key safety standard - or looking at the implications of new EU legislation such as the Energy-using Products (EuP) directive.
   • Service code LM
7. Design guideline writing. This can be a valuable aid to reducing time spent by design engineers navigating and interpreting sometimes confusing or complicated information laid-out in technical standards. Collating differing requirements across various applicable standards when considering e.g. PCB clearance requirements is another example of a potential benefit.
   • Service code DG
8. Data research and collation. This service can be of help for example when selecting suitable polymeric materials for an electrical enclosure and can include review of relevant parameters such as flammability, relative thermal index for electrical & mechanical performace, comparative tracking index, arcing and hot wire ignition resistance and so forth.
• Service code DRC
