Full title and description

St ISO 5277-1981 — ISO 5277:1981: Aromatic hydrocarbons — Determination of residue on evaporation of products having boiling points up to 150 °C. A short technical method specifying a gravimetric procedure to determine non‑volatile residue after evaporation of low‑boiling aromatic hydrocarbon products.

Abstract

ISO 5277:1981 describes a simple gravimetric test for the residue remaining after evaporation of an aromatic hydrocarbon product whose boiling point is ≤ 150 °C. A measured test portion is evaporated in a weighed dish and the increase in mass of the dish (the dried residue) is determined. The method is intended for low levels of residue down to about 1 mg per 100 ml of sample. The standard is short (2 pages) and has been withdrawn from the ISO catalogue.

Scope

This standard applies to aromatic hydrocarbon products having boiling points lower than or equal to 150 °C and specifies a laboratory procedure for determining the residue remaining after evaporation. It is intended for use where a simple gravimetric measurement of non‑volatile residue is appropriate and where detection down to approximately 1 mg per 100 ml is required. The procedure is focused on routine quality control and specification testing rather than on detailed compositional analysis.

Key topics and requirements

• Applicability: aromatic hydrocarbons and related low‑boiling products with boiling point ≤ 150 °C.
• Test principle: evaporate a measured portion in a pre‑weighed dish and determine the mass increase as the residue.
• Detection limit: nominal lower limit around 1 mg per 100 ml of sample (method sensitivity statement).
• Sample handling: care required for volatile and potentially toxic materials; safe laboratory practice recommended.
• Result reporting: mass of dried residue expressed relative to original sample volume or mass.
• Short, prescriptive procedure intended for routine QC rather than detailed analytical characterisation.

Typical use and users

Used by chemical and petrochemical quality‑control laboratories, manufacturers and suppliers of aromatic hydrocarbon products, inspection and conformity assessment bodies, and laboratories performing acceptance testing of industrial solvents and related products. Typical applications are routine batch checks, specification compliance testing and simple impurity/residue screening.

Related standards

Standards covering related residue‑on‑evaporation methods and product groups include the ISO general method for volatile organic liquids (ISO 759:1981), procedures for essential oils and other product‑specific residue tests, and various national adoptions (for example national translations/adoptions of ISO 5277). Laboratories should consult the currently valid ISO and national standards for alternative or updated procedures.

FAQ

Q: What is this standard?

A: ISO 5277:1981 is an ISO test method titled "Aromatic hydrocarbons — Determination of residue on evaporation of products having boiling points up to 150 °C" that specifies a simple gravimetric procedure to measure non‑volatile residue after evaporation.

Q: What does it cover?

A: It covers the determination of residue remaining after evaporation of aromatic hydrocarbon products with boiling points ≤ 150 °C by evaporating a measured portion in a weighed dish and weighing the dried residue. The method has a stated lower sensitivity of about 1 mg per 100 ml.

Q: Who typically uses it?

A: Chemical and petrochemical QC laboratories, solvent producers and suppliers, testing houses, and regulatory/inspection bodies that need a rapid, routine measurement of non‑volatile residue in low‑boiling aromatic products.

Q: Is it current or superseded?

A: ISO 5277:1981 has been withdrawn. Users should check for any replacement or alternative ISO or national standards (for example general residue methods such as ISO 759:1981 or product‑specific methods) that are currently valid for their application.

Q: Is it part of a series?

A: ISO 5277 is a stand‑alone method for a specific product class (aromatic hydrocarbons). It relates conceptually to other ISO residue/evaporation methods (for volatile organic liquids and product‑specific residue tests) but is not part of a numbered multipart series in the same way that some other test families are.

Q: What are the key keywords?

A: Aromatic hydrocarbons, residue on evaporation, dry residue, gravimetric, volatile organic liquids, solvent quality, ISO 5277, detection limit 1 mg/100 ml.
