BIS Certification for Ready Mix Concrete (RMC) Plants – IS 4926

BIS Certification for Ready Mix Concrete (RMC) Plants – IS 4926

Process Certification under IS 4926 with Integrated ISO 9001 Support – Expert Handholding by Praditha Engineers

With increasing demand for quality assured concrete in infrastructure, real estate, highways, metros, airports and industrial projects, many contractors and project authorities insist that Ready Mixed Concrete (RMC) should be sourced only from BIS certified RMC plants.

The Bureau of Indian Standards (BIS) operates a Process Certification Scheme for RMC plants based on IS 4926:2003 Ready Mixed Concrete – Code of Practice, integrated with IS/ISO 9001 Quality Management System requirements.

Praditha Engineers provides complete end-to-end handholding for RMC producers to obtain BIS certification and sustain compliance, led by Shri M.V.S.D. Prasada Rao (Former Deputy Director General, BIS).

What is BIS Certification for RMC?

BIS Certification for RMC is a plant-based process certification that evaluates whether the Ready-Mix Concrete facility has a robust system for:

 • control of incoming materials (cement, aggregates, admixtures, water)

 • mix design control and traceability

 • batching plant accuracy and calibration

 • production controls and dispatch

 • quality control testing and records

 • training, corrective actions and continual improvement

This certification builds confidence among:

 • contractors

 • government departments

 • infrastructure project authorities

 • consultants & third-party auditors

 • customers and end users

Applicable Standard for RMC Certification

 • IS 4926:2003 – Ready Mixed Concrete – Code of Practice

BIS assessment also checks alignment with requirements of relevant concrete standards such as IS 456 for concrete-making materials and controls.

Why BIS Certification is Important for RMC Plants

BIS certification helps RMC producers to:

 • Qualify for major infrastructure projects and tenders

 • Improve customer confidence and market credibility

 • Reduce rejections, complaints, and returned concrete

 • Establish systematic documentation and process controls

 • Improve consistency in strength, slump, and performance parameters

 • Strengthen in-house QC laboratory and testing competence

 • Ensure plant readiness for external audits and customer inspections

Many project owners increasingly prefer BIS certified RMC plants as proof of consistent quality assurance.

Who Can Apply for BIS RMC Certification?

Any Ready Mix Concrete plant, including:

 • commercial RMC producers

 • captive RMC plants (for large projects)

 • construction company owned batching plants

 • infrastructure contractors and EPC players

BIS RMC Certification Process (Overview)

Praditha Engineers supports you across every stage:

1) Certification Planning & Gap Assessment

 • review of plant readiness vs IS 4926 requirements

 • identification of gaps in QC systems, documentation, lab & calibration

2) Documentation & System Implementation

 • manuals, SOPs, records, formats

 • training support and test procedures implementation

3) BIS Application Submission

 • submission with correct scope and compliance evidence

4) BIS Audit / Assessment of Plant

BIS assesses compliance on:

 • materials storage, handling and traceability

 • plant equipment and batching controls

 • calibration and maintenance

 • production control and delivery records

 • QC testing system & records

5) Certification Grant

Based on BIS evaluation and plant compliance, certification is granted and plant becomes BIS certified.

Checklist / Documentation Required (Indicative)

 • factory/plant registration details

 • batching plant details & capacity

 • plant layout & storage arrangements

 • process flow and equipment list

 • QC laboratory details and test equipment

 • calibration records (weighing system, water measurement etc.)

 • mix designs, raw material approvals and test results

 • production and dispatch records

 • customer complaint handling system

 • training records and internal audit records

BIS has also issued a standard checklist for RMC certification assessment.

Common Challenges Faced by RMC Plants

Many RMC plants fail or face delays due to:

 • incomplete QC records and formats

 • lack of proper SOPs and system documentation

 • missing calibration / inaccurate batching system

 • poor traceability of raw materials and dispatch

 • inadequate internal testing procedures

 • lack of trained QC personnel

 • non-availability of required test equipment

Praditha Engineers solves these issues systematically through practical implementation support and audit readiness.
