BIS Certification Consultancy for Parliament Hinges | IS 362:1991 | BIS & ISI Mark Certification

Introduction

Parliament hinges are specialized door and window hardware designed to allow a door or window to open through a wide angle, including applications where approximately 180-degree opening is required. They are commonly used in construction, furniture, doors, windows and other architectural hardware applications.

The performance and durability of a parliament hinge depend on its material, dimensions, manufacturing quality, knuckle and pin construction, screw-hole arrangement and surface finish. IS 362:1991 – Parliament Hinges – Specification establishes requirements intended to ensure consistency and suitability of these hinges.

The BIS Product Manual for IS 362:1991 provides certification guidance under Scheme-I of the BIS Conformity Assessment Regulations, 2018 and can also be used by prospective applicants seeking a BIS certification licence. The Product Manual identifies Type 1, Type 2 and Type 3 parliament hinges and specifies a sample size of 6 parliament hinges.

Parliament hinges are covered under the current Hinges (Quality Control) Order, 2025. The order specifically lists IS 362:1991 – Parliament Hinges and provides 1 July 2025 as the implementation date. The current BIS compulsory-certification listing also includes IS 362:1991 under the Hinges category.

Qualitance India provides end-to-end BIS Certification Consultancy for Parliament Hinges as per IS 362:1991, including product assessment, scope and grouping guidance, documentation, testing coordination, BIS application support and factory inspection preparation.
