BIS ISI Certification for Precast Concrete Pipes with and without Reinforcement – IS 458
BIS ISI certification is mandatory for precast concrete pipes with and without reinforcement used in drainage, sewerage, culverts, and water supply infrastructure as per Indian Standard IS 458:2021. These pipes play a critical role in civil engineering projects where strength, durability, and long-term performance are essential.
IS 458:2021 was formulated and published by the Bureau of Indian Standards to define stringent quality, performance, and testing requirements for precast concrete pipes. The standard covers both reinforced concrete pipes (RCC) and non-reinforced concrete pipes, ensuring suitability for underground installations and gravity flow applications.
BIS ISI Mark certification under IS 458 assures compliance with Indian regulatory requirements, enhances acceptance in government and infrastructure projects, and builds confidence among engineers, contractors, urban local bodies, and project authorities.
IS 458:2021 – Key Quality & Performance Requirements for Precast Concrete Pipes
- (i) Manufacture of precast concrete pipes with or without reinforcement
- (ii) Classification based on diameter, load-bearing capacity, and class
- (iii) Use of controlled-grade cement, aggregates, and potable water
- (iv) Provision of reinforcement as per design requirements for RCC pipes
- (v) Compressive strength and load test compliance as specified in IS 458
- (vi) Water absorption and permeability limits for durability
- (vii) Dimensional tolerances, straightness, and surface finish criteria
- (viii) Mandatory marking, batch identification, and traceability
Overview of ISI Mark Certification for Precast Concrete Pipes (IS 458)
IS 458:2021 covers precast concrete pipes used primarily for sewerage, stormwater drainage, culverts, irrigation, and water conveyance systems. These pipes are designed for underground installation under gravity flow conditions and are widely used in municipal and infrastructure projects.
The standard specifies requirements for non-reinforced and reinforced concrete pipes of various nominal diameters and strength classes. Pipes must meet prescribed criteria for load testing, crushing strength, dimensional accuracy, and joint performance.
BIS ISI certification under IS 458 is granted only after successful product testing, factory inspection, and implementation of an effective quality control system. Certified products are permitted to carry the ISI Mark, signifying conformity to Indian Standards and suitability for use in critical infrastructure applications.
Process Required for BIS ISI Mark Certification for Precast Concrete Pipes with and without Reinforcement (IS 458:2021)
To obtain the BIS ISI Mark for precast concrete pipes with or without reinforcement under Indian Standard IS 458:2021, manufacturers must comply with the BIS Product Certification Scheme (Scheme I). This certification ensures that concrete pipes meet stringent requirements related to material quality, load-bearing capacity, durability, and performance for use in sewerage, drainage, culverts, and water conveyance systems.
Estimated Timeline: The BIS ISI certification process for precast concrete pipes generally takes around 30–45 days for Indian manufacturers and up to 180 days for foreign manufacturers, depending on factory readiness, inspection scheduling, and laboratory testing requirements.
Step-by-Step Certification Process
- Application Submission: Submit the BIS application through the Manak Online portal by providing details of precast concrete pipes, applicable Indian Standard (IS 458:2021), factory location, manufacturing process, machinery, and product range.
- Testing & Quality Readiness: Ensure availability of in-house or external testing facilities for raw material testing, compressive strength of concrete, water absorption, load test, crushing strength, and dimensional verification as prescribed under IS 458:2021.
- Factory Inspection: A BIS officer conducts an on-site inspection to verify manufacturing infrastructure, batching and curing systems, reinforcement placement (if applicable), quality control procedures, and compliance with the Scheme of Inspection and Testing (SIT).
- Sample Drawing and Testing: Precast concrete pipe samples are drawn during inspection and tested in BIS-recognized laboratories as per IS 458:2021 requirements.
- Grant of BIS License: Upon satisfactory inspection and successful test results, BIS grants the Certification Marks License (CM/L), authorizing the manufacturer to use the ISI Mark on precast concrete pipes.
Requirements to Obtain BIS ISI License for Precast Concrete Pipes (IS 458)
