test samples (or specimens)

After NIL receives the “Registration Form for PT Schemes” from the participants, test samples shall be distributed along with “INSTRUCTIONS TO PARTICIPANTS”, “SAMPLES RECEIPT FORM” and “RESULT SHEET” to the laboratories participating in the scheme. Some of the samples are prepared and tested for homogeneity by the Standard Material Research Center of CISRI (Central Iron & Steel Research Institute).

Registration fees

Registration fees should be paid as soon as the laboratory submits “Registration Form for PT Schemes”. A formal invoice will be forwarded to the participating laboratory together with the samples

Testing method

The samples will be tested by the participant's preferred methods, which are generally used for providing formal reports. However, it is preferable to use international or national consensus standard methods. If a standard method is used, please provide its title name and serial number.
