Rule 11 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 11 tells manufacturers, dealers and traders what a weight used in trade must look like and how accurate it must be. It does not list the specifications itself. It points to the Fifth Schedule, which holds the technical detail for each kind of weight. If you need to test a product range against it, a legal consultation is a sensible starting point.
Every weight used or intended to be used in any transaction or for protection must conform to the Fifth Schedule as to physical characteristics, configuration, constructional details, materials, performance and tolerances (rule 11(1)). The maximum permissible error is the one the Fifth Schedule specifies (rule 11(2)). Products of an industry governed by another law that requires its own specifications are carved out, but only on the conditions in rule 11(3). A non-conforming weight is a non-standard weight, and the Act's penalty and seizure provisions follow.
What rule 11(1) requires
Rule 11(1) opens with the words "Save as otherwise provided in these rules". It then says that every weight used or intended to be used in (a) any transaction, or (b) for protection, "shall conform, as regards physical characteristics, configuration, constructional details, materials, performance, tolerances and such other details, to the corresponding specifications laid down for such weight in Fifth Schedule."
Three points follow from the wording.
- Use, not only sale. The rule bites on a weight "used or intended to be used", so a shopkeeper who keeps a non-conforming weight for use is covered as well as the manufacturer who made it.
- Transaction or protection. Both expressions come from the Act (see its definitions in section 2); the rule borrows them. A weight used for a sale, or for the protection of living beings or things, must meet the Schedule.
- Corresponding specification. There is no single test. Each type of weight is matched with its own part of the Fifth Schedule.
The standards the Act itself recognises are in sections 7 and 8; rule 11 is the delegated-legislation layer that supplies the detail.
Rule 11(2) and (3): error and the exception
Rule 11(2) says the maximum permissible error in such a weight "shall be such as is specified in Fifth Schedule". The error limits are in the Schedule tables, and this article does not reproduce them because the scanned copy we work from is unreliable in its tables. Take the figures from the notified Schedule.
Rule 11(3) is an exception. Nothing in the rule applies to the product of an industry which is required, by or under any other law in force, to conform to other specifications on the matters in sub-rules (1) or (2), if under that law the product must conform to the specifications laid down by the International Organisation of Legal Metrology. Both parts matter: another law alone is not enough; that law must tie the product to the OIML specifications.
What the Fifth Schedule covers
The Fifth Schedule is headed "See Rule 11" and is divided into three Parts.
| Part | Subject | What the readable text shows |
|---|---|---|
| I | Weights (other than carat weights) | Five categories: iron parallelepiped weights, cylindrical knob type weights, iron hexagonal weights, bullion weights and sheet metal weights. Each has headings such as denominations, shape, material, loading holes, markings and finish. |
| II | Carat weights | Weights for weighing pearls, diamonds and other precious stones; knob weights and sheet metal weights; materials, shape and dimensions, permissible error, marking and packing. |
| III | Standard weights for testing of high capacity weighing machines | Applies to standard weights of a nominal value of 50 kg or more used to test high capacity weighing machines of accuracy class III and class IV; scope, nominal values, shape and other requirements. |
Within Part I the text lists the heads under which each category is described (denominations, shape, material, method of manufacture, loading holes, markings, finish). Weights are to carry the denomination and the maker's name or trade mark indelibly, and the denomination is given in the international form of Indian numerals. The text also mentions the Legal Metrology Officer's seals. The dimension figures and the permissible error tables are garbled in the scan and are not repeated here.
Part II is specific about material: the carat weights are to be made from rolled, drawn or extruded material and not cast, using metals such as brass, bronze, gun-metal, nickel-chromium alloy or non-magnetic stainless steel. Part III is about the heavy standard weights used to test high capacity weighing machines.
How rule 11 fits with the rest of the chain
- Standards used by officers to check your weights are dealt with in the earlier rules: see rules 3 to 6 and the First, Second and Third Schedules.
- Model approval under section 22 is a separate step. The proviso to section 22 says approval of model may not be required for some weights, including cast iron, brass, bullion or carat weights. Being exempt from model approval does not exempt a weight from rule 11.
- Verification and stamping under section 24 follows after a weight is made; see section 24 and rule 27 on periodical verification.
- Consequence of breach. A weight that is not in accordance with the standards in the Act or rules is a non-standard weight. Using or keeping it for use is penalised under section 25, and manufacture or sale under section 27. Seized weights may be forfeited under section 16. Sections 25 and 27 were amended by the Jan Vishwas (Amendment of Provisions) Act, 2023 (in force), and the Jan Vishwas (Amendment of Provisions) Act, 2026 is enacted but in force only from the date the Central Government notifies; check the notification and the articles on those sections for the amounts.
Examples
Example 1: a dealer's weight set. A grocer buys an unmarked set of iron weights from a scrap dealer. The weights carry no denomination or maker's mark. Whether the set conforms is judged against the Fifth Schedule, which calls for denomination and maker's name or trade mark on weights. Items that do not conform are at risk of seizure under section 15.
Example 2: a jeweller's carat weights. A jeweller uses carat weights to weigh stones. Part II of the Fifth Schedule is the relevant specification, and the same weights also need verification and stamping before use.
Common mistakes
- Assuming a weight that needs no model approval needs no specification. Rule 11 applies regardless.
- Reading the rule 11(3) exception as covering any industry with its own law. It applies only where that law requires conformity to OIML specifications.
- Copying error limits from a summary. Use the notified Fifth Schedule.
Need help with weights and compliance?
If you make or sell weights and want to check your products against the Fifth Schedule, or you have received a notice after an inspection, a legal consultation lets us go through the documents and the Schedule together.
Key takeaways
- Rule 11 applies to every weight used or intended to be used in a transaction or for protection.
- The technical detail and the maximum permissible error are in the Fifth Schedule, Parts I, II and III.
- Rule 11(3) exempts only products that another law ties to OIML specifications.
- Exemption from model approval under section 22 does not remove the duty to conform to rule 11.
- Non-conforming weights attract the Act's penalty, seizure and forfeiture provisions.
