Full title and description

St ISO 2733-1983 rus — Vitreous and porcelain enamels. Apparatus for testing with acid and neutral liquids and their vapours. Russian-language edition of ISO 2733:1983 describing the test apparatus used to determine resistance of flat enamelled surfaces to attack by acidic and neutral liquids and their vapours.

Abstract

This standard specifies the design and essential components of the apparatus used to test the resistance of vitreous and porcelain enamels to chemical attack by acid and neutral liquids and their vapours. The apparatus allows simultaneous exposure to liquid and vapour phases during a single test period and defines materials, dimensions and key accessories (glass cylinder, reflux condenser, heating arrangement, thermometer and specimen supports) required for reproducible testing.

Scope

Specifies the apparatus (not the step-by-step test method) to be used when determining the resistance of flat surfaces of vitreous and porcelain enamels to attack by specified acid and neutral liquids and their vapours. Applicable to laboratory evaluation and comparative testing of enamelled finishes; it defines the construction, materials and principal dimensions needed to ensure comparable test conditions.

Key topics and requirements

• Definition of the principal components of the test apparatus: borosilicate glass cylinder, reflux condenser (e.g., Liebig‑West), external heater, thermometer with standard ground joint, specimen supports (triangular plates) and sealing/joints.
• Materials and glass standards: use of borosilicate glass that meets laboratory glassware thermal shock and strength requirements to withstand temperature differentials specified for the test.
• Configuration and dimensions: nominal jacket/condensing length and preferred joint types to provide reproducible vapour-liquid exposure.
• Thermal control: heating arrangement and thermometer range suitable for boiling or elevated-temperature exposure as required by the corresponding test methods.
• Compatibility: apparatus specified so it can be used with the relevant ISO test methods for chemical corrosion and boiling tests (liquid and vapour phases simultaneously).
• Safety and laboratory practice: recommendations implicit in material choices and construction to reduce breakage and allow safe handling of corrosive liquids and vapours.

Typical use and users

Laboratories performing enamel durability testing, enamel and porcelain manufacturers for quality control and R&D, coatings and surface‑treatment laboratories, conformity assessment and certification bodies, and standards committees that reference or update test methods for enamel corrosion resistance.

Related standards

ISO 2733:1983 was later superseded by updated methods and parts of the ISO series for vitreous and porcelain enamels. Relevant and related documents include ISO 28706‑2 (subsequent method for resistance to chemical corrosion by boiling acids/neutral liquids and their vapours), and other enamel test standards in the ISO 2700–2899 range (for example ISO 2742, ISO 2743, ISO 2744 and related national/adopted versions such as DIN/ČSN implementations). The document forms part of the ISO/TC 107 body of work on vitreous and porcelain enamel coatings.

FAQ

Q: What is this standard?

A: It is the Russian-language edition (Ст ISO 2733-1983 (rus)) of ISO 2733:1983, which specifies the apparatus used to test the resistance of vitreous and porcelain enamels to acidic and neutral liquids and their vapours.

Q: What does it cover?

A: It covers the design, key components and material requirements of the test apparatus (glass cylinder, condenser, heater, thermometer, specimen supports and related fittings) so that enamel resistance tests involving liquid and vapour phases can be performed reproducibly.

Q: Who typically uses it?

A: Test and quality-control laboratories, enamel and porcelain manufacturers, coatings researchers, conformity assessment bodies and standards developers.

Q: Is it current or superseded?

A: The 1983 edition is withdrawn/superseded. Subsequent ISO work replaced and consolidated related test methods (for example under ISO 28706‑2 and later editions). Users should consult the latest ISO/TC 107 publications for current test methods.

Q: Is it part of a series?

A: Yes — it belongs to the family of ISO standards addressing vitreous and porcelain enamels (series of related test methods and apparatus specifications managed by ISO/TC 107). Several adjacent numbers address specimen preparation and other corrosion or durability tests.

Q: What are the key keywords?

A: Vitreous enamel, porcelain enamel, test apparatus, corrosion, acid, neutral liquid, vapour, borosilicate glass, enamel durability, ISO 2733.
