Material Test Report (MTR)
/glossary/mtrDetailed test results document covering chemistry, mechanicals, and dimensional compliance.
An MTR is the heat-wise test record: chemistry, mechanicals, and the checks the mill actually ran. Kanpur PWD, JJM, and sugar-mill stores read it against the PO before they cut pipe. EN 10204:2004 Type 3.1 is the usual inspection certificate that carries those results. RP Sales sends an MTC with each dispatch. Lots leave 83/124, Steel Market, Bartan Bazar (208014) on an ex-warehouse Kanpur basis, GST 18% extra as the budgeting basis.
In detail
Material Test Report (MTR) is the comprehensive document detailing all test results for a specific heat of steel, including chemical composition analysis (C, Si, Mn, P, S, Cr, Mo, Ni), mechanical test results (yield strength, tensile strength, elongation, hardness), and dimensional verification. MTR is synonymous with MTC in common usage, though technically MTR refers specifically to the test data portion. The MTR provides the evidence of compliance to specified grades like SA192, SA210, or ASTM A53.
What an MTR is, and what it is not
An MTR is the test-data sheet for one heat. It prints ladle or product analysis and the mechanical results the mill measured on that heat. Indian pipe buyers also say MTC. The two labels travel on the same paper more often than they travel as two files.
EN 10204:2004, Metallic products. Types of inspection documents, published 25 October 2004 (BSI Knowledge, retrieved 2026-09-05), is the document-type standard. Type 2.1 is a declaration of compliance with no test results. Type 2.2 is a test report from non-specific inspection. Type 3.1 is an inspection certificate with specific results, validated by the manufacturer's authorized inspection representative independent of manufacturing. Type 3.2 adds validation by the purchaser's representative or an inspector designated under official regulations.
An MTR is not an ISI mark. The mark is mill licence under the relevant Indian Standard. The certificate is heat-wise test data. Tender language often wants both. An MTR is not IBR Form III-B. Form III-B is the manufacture-and-test certificate for tubes. Form III-C is the certificate for boiler mountings and fittings. Form III-A is the certificate for steam pipes.
A factory ISO 9001 certificate is not an MTR. ISO 9001 proves a quality system. It does not prove that this heat of IS 1239 Medium or SA210 A1 met the ordered chemistry.
Who should demand the test sheet, and who should not treat Type 3.2 as automatic
Demand a Type 3.1 inspection certificate on every industrial pipe lot that leaves Kanpur. That is the B2B default already used on this site. PWD and JJM contractors, fire-system installers, borewell contractors, and sugar-mill stores all need heat identity on the paper and on the steel.
Treat "IBR" or "critical service" as a prompt to read the controlling tender, approved quality plan, and governing authority, not as a universal Type 3.2 trigger. EN 10204 creates document types, not pressure or temperature cut-offs. Name Type 3.2 when one of those controlling documents names that route. Form III-C remains the component certificate for mountings and fittings; it does not by itself specify Type 3.2 or a TPI visit.
Do not treat Type 3.2 as a substitute for Form III-B on a boiler tube. Do not treat Type 3.1 as a substitute for Form III-C on a mounting or fitting. Do not skip the certificate on a 25 NB house-connection lot because the run looks small. Heat identity still matters when a length is cut.
Hydraulic and printing-cylinder shops in Dada Nagar still need the tube certificate (grade, heat, delivery condition). They also need a bore or roughness report when the drawing names H8 or a Ra limit. That second sheet is not the MTR.
EN 10204 types against a Kanpur pipe PO
Use the table to pick the document type before the mill prints the sheet. The four rows are the EN 10204:2004 set already described on the Type 3.1 vs 3.2 page. The last column is the Kanpur buying decision, not a new test method.
| Type | What it carries | Who validates it | Kanpur buying use |
|---|---|---|---|
| 2.1 | Compliance statement, no test results | Manufacturer | Insufficient for a heat-wise PO |
| 2.2 | Non-specific test results | Manufacturer, no independent QC sign-off | Rare on industrial pipe; reject if the PO named 3.1 |
| 3.1 | Specific heat results | Mill inspection representative independent of manufacturing | Default B2B pack from the Kanpur yard |
| 3.2 | Specific heat results plus second validation | Mill plus purchaser or officially designated inspector | Only when the tender or ITP names it |
TPI by SGS, Bureau Veritas, Lloyds, or TUV is coordinated at the Kanpur yard when the RFQ names the agency. That appointment is a contract line. It is not automatic because the grade is SA213 or the buyer is a sugar mill.
How to specify the certificate on an RFQ
Write the document type on the same line as the steel. A late "send 3.2" after the mill has already printed 3.1 is how a Lucknow site holds a truck. RP Sales returns a technical and commercial RFQ response within 4 working hours.
- Product: process, standard, grade, NB or OD, wall or class, length, quantity, end finish, coating.
- Document: EN 10204 Type 3.1 or Type 3.2. Do not write "MTC" alone on a Type 3.2 tender.
- Heat identity: stencil on the pipe, tag on the bundle, same number on the certificate and the dispatch challan.
- IBR: Form III-A if the line is a steam pipe, Form III-B if the line is a tube, Form III-C if the line is a boiler mounting or fitting.
- TPI: name SGS, Bureau Veritas, Lloyds, TUV, or the buyer-nominated Inspecting Authority.
- Scan before dispatch when the ITP says so. Delivery ex-warehouse Kanpur or FOR destination. GST 18% extra.
Worked check on a 25 NB Medium lot
Take 25 NB Medium from the site class chart and weight table: OD 33.7 mm, wall 3.2 mm. W = (33.7 − 3.2) × 3.2 × 0.02466 = 30.5 × 3.2 × 0.02466 = 2.41 kg/m. A 6 m length is 14.5 kg. Two hundred lengths are 14.5 kg × 200 = 2.90 MT.
The MS ERW price list band for 25 NB Medium is ₹56-63 per kg as of 24 May 2026, ex-warehouse Kanpur, GST 18% extra. That steel line is about 2.90 × 56,000 = ₹1.62 lakh to 2.90 × 63,000 = ₹1.83 lakh before freight.
The certificate that travels with those 200 lengths must name IS 1239, Medium (Class B), 25 NB, the heat number, chemistry, yield and tensile for the ordered YST grade, and hydrotest. If the sheet says 50 NB or Heavy class, hold the lot. Theoretical mass is a commercial check when the invoice is per kilogram. Acceptance still follows the ordered class and its standard.
Common MTR mistakes at receiving
In practice, the first failure is a heat on the stencil that does not appear on the certificate. The quality cluster treats that as a broken traceability file. Hold the bundle. Do not cut the first length while someone "finds the other PDF".
The second failure is a Type 2.1 or a generic mill letter offered as Type 3.1. Type 2.1 has no test results. It cannot support a PWD or JJM clause that asked for specific inspection.
The third failure is a 3.1 sheet offered as Form III-B on a boiler-tube heat. The UP boiler inspector registers the IBR form, not the EN document. Order Form III-B at RFQ stage.
The fourth failure is reading only the grade line and skipping phosphorus and sulphur maxima. The MTC-reading cluster on this site treats P and S as maxima. A value above the limit is a hold, even when tensile looks comfortable.
Standards that govern the certificate
EN 10204:2004 is the inspection-document standard. BSI Knowledge lists it as current, published 25 October 2004, identical to EN 10204:2004, and replacing the withdrawn 1991 edition. Its public contents list covers non-specific inspection, specific inspection, validation and transmission, transmission by an intermediary, and the summary of document types.
The product standard still owns the numbers on the sheet. IS 1239 owns ERW water-tube chemistry and hydrotest. ASTM A53 and ASTM A106 own those carbon-pipe grades. SA192, SA210, and SA213 own the boiler-tube grades. Copy the edition named on the PO.
Under the Indian Boiler Regulations, 1950, steam pipes use Form III-A, tubes use Form III-B, and boiler mountings and fittings use Form III-C. Keep those forms on the IBR line. Keep EN 10204 on the mill-certificate line.
Reading MTRs on Kanpur dispatches
Panki sits about 12 km from the Bartan Bazar stockyard. Fabricators there take boiler and process lots that need the certificate in the same envelope as the challan. Dada Nagar, about 8 km, takes precision-tube certificates plus a bore report when the drawing names one. Jajmau, about 10 km, takes water and process ERW with a Type 3.1 sheet.
The yard address on the invoice is 83/124, Steel Market, Bartan Bazar, Afim Kothi, Basanti Nagar, Juhi, Kanpur 208014. Intra-city pickups still need the heat match. A Coolie Bazar contractor who loads 25 NB Medium for a JJM house-connection run cannot sort heats after the truck reaches the ward.
See MTC review guide, MTC verification checklist, steel pipes in Kanpur, and the Kanpur steel market. Stock items listed on the glossary lead-time entry dispatch in 3-7 days. Mill-direct standard grades take 14-21 days. Mill-direct alloy (SA213 T11/T22) takes 21-30 days.
Heat number, stencil, and challan
The heat number is the furnace-melt identity. It must appear on the pipe stencil or bundle tag, on the MTR, and on the dispatch challan. One missing field breaks the chain. A remark after blasting is not a new heat.
When a length is cut at the Kanpur yard, transfer the heat mark onto the offcut before the remnant goes back into stock. Short pieces lose the original stencil. The next buyer then holds a bare tube with a certificate that names a heat they cannot find.
A mixed truck to Lucknow or Patna can carry more than one heat. The packing list must list each heat against its bundle count. Do not let the driver treat "one MTC for the lorry" as enough.
IBR forms versus the mill certificate
The mill certificate answers chemistry and mechanicals on the ordered specification. The IBR form answers the Central Boilers Board route for that component. They sit side by side on a sugar-mill shutdown pack. One does not replace the other.
For a SA213 T11 superheater tube, the pack is Type 3.1 or 3.2 plus Form III-B. For a steam pipe under IBR, the pack is the mill certificate plus Form III-A. For a valve or mounting, Form III-C is the component certificate.
See IBR Form III-C only when the line is a mounting or fitting. See the Form III-C guide for the same split. A Panki inspector who asks for "IBR papers" wants the form that matches the component, not a thicker MTR.
The document pack that leaves Kanpur
A complete pack is the commercial invoice, the dispatch challan, the MTR / MTC, the e-way bill, and any TPI release or IBR form the PO named. Daily dispatch from Kanpur covers Uttar Pradesh, Bihar, Madhya Pradesh, Delhi NCR, and Uttarakhand.
City landings that reuse the same certificate rules include steel pipes in Agra, Prayagraj, Varanasi, Gorakhpur, Jhansi, and Bareilly. The destination PIN changes the e-way bill. It does not change the heat-match rule.
Send the RFQ with the document type already written. A store that opens the crate first and looks for paper later is how a replacement lot misses the shutdown window.
Where you'll meet this in procurement
You will meet Material Test Report (MTR) in inspection plans, dispatch packs, and tender checklists. Keep heat identity, certificate type, and any third-party witness tied to the order so Material Test Report (MTR) is usable evidence at site acceptance—not a loose attachment after delivery.

Key points
- MTR is the heat-wise test data. Indian buyers often print it on the same paper as the MTC.
- EN 10204:2004 Type 3.1 is the default inspection certificate. Type 3.2 is only when the tender or ITP names it.
- Type 3.1 is not Form III-B. Form III-B is for tubes. Form III-C is for boiler mountings and fittings.
- A 25 NB Medium lot is 2.41 kg/m and 14.5 kg per 6 m on the site weight table. The certificate must name that class.
- Heat on stencil, certificate, and challan must match before the Kanpur load is cut.
