الأسئلة الشائعة حول IS 1200 PART 26
?How is acid-resistant lining quantified on curved or conical surfaces according to the standard?▼
Per IS 1200 Part 26 (1987), acid-resistant lining on curved or conical surfaces is measured based on the actual developed surface area. This involves calculating the lining area by unfolding the curved or conical surface into a flat plane, ensuring accurate coverage and thickness representation. Standard geometric formulas are used, such as A = 2c0rh for cylinders and A = c0rl where l = a0r2 + h2 for cones, with r being radius and h height.
?What guidelines exist for including joints and fillers when measuring acid-resistant lining?▼
Although IS 1200 Part 26 (1987) does not explicitly detail joint and filler measurement, standard practice includes joints and fillers as part of the total finished lining surface area. Measurements encompass all filled joints, sealants, and overlaps integral to the lining system, ensuring complete protective coverage is accounted for in square meters. Any gaps filled during lining application are also included.
?What is the correct procedure for recording and rounding dimensions when measuring acid-resistant lining?▼
According to IS 1200 Part 26, dimensions must be taken on the finished surface and recorded with precision. Measurements should be rounded off following IS 2:1960 standards, maintaining the specified number of significant figures as defined in the standard. This approach guarantees uniformity and prevents ambiguity in dimension recording.
?Does the code specify different measurement approaches for tanks with and without capping?▼
IS 1200 Part 26 treats measurement of acid-resistant lining on tanks with and without capping identically, referring both cases to the method described in Clause 3.2. This unified method involves calculating the surface area of the lining, including deductions for openings or unlined portions, and expressing quantities in square meters without differentiating based on the presence of capping.
?Which items and processes are accounted for in the measurement of acid-resistant lining?▼
The standard encompasses all integral components of acid-resistant lining work for measurement purposes. This includes surface preparation such as cleaning and priming, application of acid-resistant materials (tiles, bricks, coatings), joint filling and finishing with acid-resistant mortars or sealants, and any repair or patching activities within the lining scope. Measurements are made by total lined surface area in square meters, covering all listed operations.
