In pursuance of Sub rule 1 of Rule 15 of the Bureau of Indian Standards Rules, 2018, the Bureau of Indian Standards hereby notifies that Indian standards, particulars of which are given
**Executive Summary**
This notification from the Bureau of Indian Standards, dated July 10, 2026, announces the establishment of six new or revised Indian Standards effective as of July 9, 2026. It provides a transition period for four specific standards, which will run concurrently with older versions until their final withdrawal on January 9, 2027. The document serves to update technical requirements for industrial components, machinery safety, and material specifications.
**Key Points / Main Content**
* **Establishment of Standards**
* Six Indian Standards were officially established on July 9, 2026, under the Bureau of Indian Standards Rules, 2018.
* Revised standards for grooved pins, hydraulic housings, industrial truck platforms, and machinery interlocking devices have been introduced to replace older versions.
* **Mechanical and Hydraulic Components**
* **IS 7386:2026 / ISO 8741:2025 (Third Revision):** Sets specifications for reverse-taper grooved pins with half-length progressive grooves.
* **IS/ISO 7425-2:2021 (First Revision):** Details dimensions and tolerances for rod seal housings in hydraulic fluid power cylinders using elastomer-energized, plastic-faced seals.
* **Industrial Safety and Equipment**
* **IS 12157:2026 (First Revision):** Outlines construction requirements for work platforms on powered industrial trucks specifically intended for maintenance purposes.
* **IS 16812:2026 / ISO 14119:2024 (First Revision):** Governs machinery safety by establishing principles for the design and selection of interlocking devices associated with guards.
* **New Specifications and Calibration**
* **IS 19592:2026:** Establishes a new standard for the calibration of gauge block comparators.
* **IS 19841:2026:** Provides the specification for Galvanizing Grade (GG) Zinc Alloy Ingots used for the hot-dip galvanizing of steel.
* **Timeline for Transition and Withdrawal**
* For standards with existing versions (Items 1–4), the previous versions will remain valid alongside the new versions until January 9, 2027.
* New standards for gauge block calibration and zinc alloy ingots (Items 5–6) are effective immediately without a withdrawal period for prior versions.
**Impact Analysis**
**Manufacturers and Industrial Suppliers**
**Impact**
Manufacturers of industrial pins, hydraulic cylinders, and zinc alloy ingots are now subject to updated technical specifications and tolerances.
**Action Required**
They must align their production processes with the 2021/2026 revisions and ensure full compliance before the January 9, 2027 withdrawal of previous standards.
**Safety and Maintenance Personnel**
**Impact**
The revised standards for powered industrial truck work platforms and machinery interlocking devices change the criteria for equipment safety and maintenance.
**Action Required**
Maintenance teams must review and update the construction of work platforms and the selection of interlocking devices to meet the updated safety principles of IS 12157:2026 and IS 16812:2026.
**Calibration Laboratories**
**Impact**
The introduction of IS 19592:2026 provides a formal standardized procedure for gauge block comparator calibration.
**Action Required**
Laboratories must adopt the new standard for their calibration services and update their quality manuals accordingly.
