Plywood Ka Stamp Kaise Padhein? IS 303, IS 710, Grade, AA/AB/BB aur ISI Licence Check

Stamp hi plywood ka "aadhaar card" hai

Har genuine plywood sheet ke face par ek stamp hota hai. Isme 5–6 cheezein likhi hoti hain, aur yahi batati hain ki sheet kis kaam ki hai aur asli hai ya nahi. Dukaan par 2 minute stamp padh lijiye – 10 saal ka pachtaava bach jaata hai.

Stamp par aam taur par ye milta hai:

Stamp par kya likha hai	Matlab
ISI mark	BIS (Bureau of Indian Standards) ka certification
IS number (jaise IS 303, IS 710)	Kis standard ke hisaab se bana hai
CM/L-xxxxxxx	ISI licence number – isi se asli-nakli check hota hai
Grade (MR / BWR / BWP)	Gond kitna paani jhel sakta hai
Type (AA / AB / BB)	Face aur back ki surface quality
Thickness (jaise 19mm)	Sheet ki motai
Brand ka naam, batch / date	Kisne kab banaya

1. IS number: IS 303 ya IS 710?

• IS 303 – general purpose plywood. Isme do hi grade hote hain: MR (moisture resistant, jise market mein commercial ply kehte hain) aur BWR (boiling water resistant).
• IS 710 – marine plywood, yaani BWP (boiling water proof) grade – sink cabinet, bathroom aur nami wali jagah ke liye.

Dhyan dein: agar stamp par IS 303 ke saath BWP ya IS 710 ke saath MR/BWR likha hai, toh baat milti nahi. Dukaandar se seedha poochiye ki asli grade kya hai.

Baaki common IS numbers:

IS number	Product
IS 1659	Block board
IS 2202	Flush door
IS 12406	MDF
IS 5509	Fire retardant plywood

2. Grade: MR, BWR, BWP

Grade gond batata hai, lakdi nahi:

• MR – sukhe kamre (bedroom wardrobe, bed, TV unit)
• BWR – kitchen, ground floor, nami wali deewar
• BWP – sink ke neeche, bathroom, balcony

"Gold", "Club", "Platinum" jaise naam brand ki series ke naam hote hain – grade nahi. Grade hamesha stamp par MR/BWR/BWP ke roop mein dekhiye.

3. AA, AB, BB kya hai?

Ye surface quality batata hai – pehla akshar face (saamne wali side), doosra back (peeche wali side):

• AA – dono taraf achhi, saaf surface
• AB – saamne achhi, peeche thodi kam
• BB – dono taraf normal surface

Jahan dono taraf laminate lagna hai, wahan surface ka itna farak nahi padta – mazbooti grade aur core se aati hai. Jahan polish ya veneer dikhega, wahan AA ya AB face behtar hai.

4. CM/L number se ISI licence kaise check karein?

Ye sabse kaam ki cheez hai, kyunki ISI ka logo copy ho sakta hai, licence ka record nahi.

1. Phone par sarkari BIS Care app install kijiye (Bureau of Indian Standards ka official app).
2. Verify Licence Details kholiye.
3. Stamp par likha CM/L number daaliye.
4. Result mein dekhiye: company ka naam, product aur brand sheet se milte hain ya nahi, aur licence active hai ya nahi.
5. Record nahi mila, ya details alag hain – sheet mat lijiye. Isi app mein shikayat (complaint) bhi kar sakte hain.

2025 se plywood, block board aur flush door par ISI mark zaroori hai. Bina ISI ki sheet lena hi nahi chahiye.

5. Thickness aur baaki details

• Stamp par likhi thickness caliper se naap kar check kijiye – thoda bahut farak normal hai, 2mm kam nahi.
• Ek kaam ki saari sheets ek hi batch ki ho toh shade aur thickness ek jaisi rehti hai.

Thickness ki poori guide: Plywood size aur thickness chart.

Laminate lagne se pehle ek kaam zaroor karein

Laminate lagte hi stamp chhup jaata hai. Isliye har sheet ke stamp ki photo le lijiye aur GST bill sambhal kar rakhiye – warranty claim aur shikayat dono mein yahi kaam aate hain. Bill par brand, grade aur thickness likhwaiye.

FAQ

IS 303 aur IS 710 mein kaunsa better hai? Better-worse nahi, jagah ka sawal hai. Sukhi jagah aur kitchen ke liye IS 303 (MR/BWR), lagataar nami wali jagah ke liye IS 710 (BWP/marine).

Kya IS 303 BWP ho sakta hai? IS 303 mein MR aur BWR grade hote hain; BWP/marine IS 710 mein aata hai. Aisa stamp dikhe toh poochiye.

CM/L number nahi hai toh? Genuine ISI mark ke saath licence number hota hai. Number nahi hai toh sheet mat lijiye.
