GOST 29093-91 PDF

Full title and description

GOST 29093-91 — "Зонты. Общие технические условия" / "Umbrellas. General specifications". Interstate (GOST) standard that establishes classification, technical requirements, test methods, marking, packing, storage and manufacturer guarantees for umbrellas and parasols intended for protection from atmospheric precipitation and solar radiation.

Abstract

This standard defines types and sizes of umbrellas (individual and collective use, rain and sun/ beach umbrellas), required materials and workmanship, mechanical performance and durability criteria, water-resistance and corrosion-protection requirements, test and inspection methods (including cyclic opening/closing and water penetration tests), and requirements for marking, packaging and manufacturer guarantees. It also lists normative references and illustrative appendices covering assemblies and protective coatings.

Scope

The standard applies to umbrellas (including parasols and beach umbrellas) for individual and collective use designed to protect people from rain and solar radiation. It covers product classification, dimensional and mass limits for different umbrella types (including special limits for children's and adolescent models), materials and coatings, functional and durability requirements, inspection and test methods, and requirements for marking, packaging, storage and manufacturer guarantees. Certain clauses may be applied or modified by agreement between manufacturer and consumer via technical descriptions.

Key topics and requirements

• Classification of umbrellas by purpose (rain, sun, beach), construction (folding, cane, tent, canopy) and user group (adult, children, adolescent, collective).
• Dimensional and mass characteristics (specified nominal diameters and maximum masses for various types; lighter limits specified for children's models).
• Materials and coatings requirements for canopies, frames and metal parts (waterproof fabrics, film covers, corrosion- and wear-resistant coatings where applicable).
• Workmanship and appearance: symmetry of canopy, permissible defects, seam placement and fabric pattern alignment tolerances.
• Mechanical performance: opening/closing operation, fixation forces for telescopic parts, minimum cyclic durability (e.g., 700 cycles for treated fabric canopies, 350 cycles for film canopies).
• Tests and inspection methods: visual inspection, dimensional and mass checks, cyclic opening/closing, water penetration / rain simulation, corrosion/finish testing and impact/handle strength tests.
• Marking, labeling and documentation: product mark, manufacturer name/address, model designation, date of manufacture, standard designation, and mandatory consumer information (warranty, care/operation instructions).
• Packing, transportation and storage requirements and manufacturer guarantees (typical warranty period established by the standard).

Typical use and users

Used by umbrella and parasol manufacturers for product design and quality control; by testing laboratories and inspection bodies to perform acceptance and type tests; by importers, distributors and retailers to verify compliance and labeling; by procurement officers and specification writers setting purchase requirements; and by national conformity and certification bodies when assessing products against regional requirements.

Related standards

The standard references a number of GOST normative documents governing fabrics, coatings, corrosion testing and testing methods (examples include fabric and textile standards, coatings/corrosion standards and dimensional/inspection standards). It replaces earlier O Standards and is used together with industry technical descriptions and design documentation. Manufacturers commonly consult the normative references cited in the standard when applying its requirements.

Q: What does it cover?

A: It covers types and sizes, technical requirements for materials and workmanship, performance and durability criteria (including cyclic tests and water-resistance testing), inspection and test methods, marking and packaging requirements, transport and storage, and manufacturer guarantees.

Q: Who typically uses it?

A: Umbrella manufacturers, product designers, quality control and testing laboratories, importers and retailers, procurement specialists, and conformity assessment bodies use the standard to specify, test and verify umbrellas.

Q: Is it current or superseded?

A: The standard is the GOST designation GOST 29093-91 (approved 1991, in force from 1 January 1993) and has been maintained/reissued in subsequent printings; users should check their national/regional standards registry for any newer national technical regulations or amendments that might affect mandatory applicability in a particular country or economic union.
