Cement fineness measurement accuracy directly affects construction quality, material performance and laboratory testing. In that regard, BIS Certification of Permeability Apparatus (Blaine Type) plays an important role for manufacturers supplying cement testing equipment to India. The Blaine permeability apparatus is one of the most common pieces of equipment applied by laboratories, quality control centers, research institutes and construction materials testing facilities for measuring the specific surface area of cement.
IS 5516:1996 determines the standards regarding design, fabrication and functional parameters of the permeability apparatus. In order to gain regulatory approval and prove that manufacturing meets relevant standards, companies should pass through testing, assessment of documentation, certification and other procedures. The regulatory approval provides assurance regarding product quality and increases the trust of construction companies in the tested instruments.
This is the Indian Standard for Permeability Apparatus (Blaine Type) used in cement testing laboratories to determine the fineness of cement. The standard ensures accuracy, consistency, and reliability in measuring the air permeability of powdered materials. As per BIS, the Blaine type apparatus is:
BIS authorisation under IS 5516:1996 is required for businesses involved in manufacturing, importing, or supplying Blaine-type Permeability Apparatus in India.
Applicable to:
To ensure high quality, reliable functioning and precise calibration of the Blaine permeability apparatus used in construction laboratories, BIS specifies minimum performance requirements under IS 5516:1996. This testing process makes sure that the apparatus can accurately determine the specific surface area of cement. The BIS testing parameters and quality checks for the Permeability Apparatus are listed below:
The BIS Approval process provides verification that the Permeability Apparatus (Blaine Type) conforms to the standard specifications mentioned in IS 5516:1996. This systematic process is regulated by the Bureau of Indian Standards (BIS) and includes the following steps:
The Foreign manufacturers must designate an Authorized Indian Representative (AIR) in India. The representative is the local point of contact for the Bureau of Indian Standards (BIS) and manages all compliance and regulatory requirements in India.
After the manufacturer obtains BIS certification, the ISI Mark for the Permeability Apparatus (Blaine Type) must be applied in a clear manner on the product body and/or its identification plate. The marking must also include the manufacturer’s identification details and the BIS licence number (CM/L).
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
The cost associated with obtaining BIS certification for the Permeability Apparatus (Blaine Type) comprises the costs of application, type testing, plant inspection, license issuance and permission to mark the apparatus. All the above costs will be charged by BIS under Scheme-I of the BIS Conformity Assessment Regulation and will depend on different factors.
Note:
Adherence to the IS 5516:1996 standard guarantees that the Permeability Apparatus (Blaine Type) offers highly reliable performance in cement fineness tests. The process of certification provides the necessary proof that the equipment has been tested against certain technical requirements. In addition, the certification may help with achieving more consistent measurements and with maintaining higher laboratory credibility and quality control standards. Compliance may be beneficial for the manufacturer since it helps with meeting the market needs and expectations regarding standardized testing processes.
Apparatus (Blaine Type) as per IS 5516:1996 includes technical and organizational measures such as the evaluation of technical specifications of products, documentation control, and conformance assessment. EVTL India is happy to provide professional consultation and assist companies in obtaining BIS Certification for Permeability Apparatus (Blaine Type) by following all necessary steps.
