- 3. Scope of IS 962 : 1989 This code lays down the recommendation for: 1. Sizes of drawings 2. Layout of drawings 3. Reproduction of drawings 4. Folding of prints 5. Scales 6. Projection 7. Line work 8. Lettering and dimensioning 9. Graphical symbols 10. Abbreviations 11. Conventional Representation of Materials 12. Number of Buildings & Parts of Buildings 13. Designation of Rooms & Other Areas 14. Coloring the Plan Rohan Dasgupta
- 4. Sizes of Drawings: The original drawing sheet should be made on the smallest sheet permitting the necessity clarity and resolution. Table 1: Preferred Sizes Designation Dimension (mm) A0 841 X 1189 A1 594 X 841 A2 420 X 594 A3 297 X 420 A4 210 X 297 Rohan Dasgupta
- 5. Layout of Drawings: For details about layout, reference shall be made to IS 10711 : 1983. Table 2: Drawing Spaces Recommendations are also provided for revision, numbering of drawing sheets, repetition of drawing numbers and reproduction of drawing sheets. Designation Dimension (mm) Drawing Space (mm) A0 841 X 1189 821 x 1159 A1 594 X 841 574 x 811 A2 420 X 594 400 x 564 A3 297 X 420 277 x 390 A4 210 X 297 180 x 277 Rohan Dasgupta
- 6. Folding of Prints: Rohan Dasgupta
- 7. Scales: Scale is the amount by which a real object is reduced (or enlarged) to represent it with accurate size on a drawing sheet. Image Courtesy: https://goo.gl/XcpD2C Original Size Scaled Down Size Scaled Up Size Rohan Dasgupta
- 8. What is x:y? Think and write the answers in your notebook. You have 2 minutes. Thought Bubble: Rohan Dasgupta
- 9. x:y is a scale where 1 unit of length in real ≡ x/y units of length in drawing For example, 1:100 is a scale where 1 unit of length in real ≡ 1/100 or 0.001 unit of length in drawing If the unit of length is metre, then 1 m in real ≡ 0.001 m or 1 cm in drawing Thought Bubble: Answer… Rohan Dasgupta
- 10. Scales: Scale is the amount by which a real object is reduced (or enlarged) to represent it with accurate size on a drawing sheet. Category Recommended Scales Enlargement Scales 50:1 20:1 10:1 5:1 2:1 Full Size 1:1 Reduction Scales 1:2 1:5 1:10 1:20 1:50 1:100 1:200 1:500 1:1000 1:2000 1:5000 1:10000 Rohan Dasgupta
