Full title and description

ISO 9033:1989 — Aluminium ores — Determination of the moisture content of bulk material. This International Standard specifies a laboratory procedure for determining the moisture content of bulk aluminium ore samples, including guidance for handling adhesive or excessively wet samples and for correcting results affected by sprayed water or rainfall.

Abstract

Applies to samples taken from bulk aluminium ores (shipments, stockpiles and similar). The standard defines test portion selection, drying procedure, number of determinations, expression of results and calculation of consignment moisture. Annex A gives an alternate method for samples that are adhesive or too wet to sieve, crush or divide; Annex B provides methods for correcting moisture results when samples have been exposed to sprayed water or rainfall.

Key bibliographic and lifecycle information above is based on the ISO record for ISO 9033:1989.

Scope

Specifies methods for determining the moisture content of bulk aluminium ore test portions taken from shipments, stockpiles and similar sources. It covers sampling considerations for preparing test portions, the drying method for moisture determination, calculation and expression of results for individual samples and consignments, and special procedures to correct results for water introduced by spray systems or rainfall; it also includes an alternate technique for handling very wet or adhesive samples.

Key topics and requirements

• Definition of test portions and requirements for the number of determinations per consignment.
• Apparatus and controlled drying procedure to determine moisture content (oven drying method and calculation of moisture by mass loss).
• Procedures for preparing samples from bulk material, including guidance when sieving, crushing and dividing are difficult due to adhesiveness or excessive wetness (Annex A).
• Methods for correcting measured moisture for effects of sprayed water or rainfall (Annex B).
• Expression and calculation of results for individual samples and combined consignment results, with instructions for reporting.

Typical use and users

Used by mining and minerals laboratories, quality control and inspection teams at alumina/aluminium producers, trade inspectors and customs authorities, shipping and receiving personnel for bulk ore consignments, and standards bodies that adopt or reference ISO chemical/mineral analysis methods. National standards bodies and testing laboratories also use ISO 9033 as the basis for identical or modified national standards.

Related standards

ISO 9033:1989 has been adopted or referenced in national and regional standards (for example AS 2932.2-2002 — Aluminium ores: Determination of the moisture content of bulk material — reproducing ISO 9033:1989 with national modifications). Regional standards organizations have also produced equivalent publications referencing the ISO method. Some national catalogs may show differing national status entries (e.g., withdrawn or adopted) depending on local revision history.

FAQ

Q: What is this standard?

A: ISO 9033:1989 is an International Standard that specifies a laboratory method for determining the moisture content of bulk aluminium ores.

Q: What does it cover?

A: It covers preparation of test portions from bulk ore, the drying procedure to measure moisture by loss on drying, how to calculate and report moisture for samples and consignments, and special procedures for very wet/adhesive samples and for correcting results affected by sprayed water or rainfall (Annexes A and B).

Q: Who typically uses it?

A: Mining and minerals testing laboratories, alumina/aluminium producers, quality and inspection personnel for shipments and stockpiles, trade inspectors, customs authorities, and national standards bodies adopting or referencing the method.

Q: Is it current or superseded?

A: According to the ISO record the 1989 edition remains the published International Standard; it has been reviewed and confirmed in ISO review cycles and was indicated by ISO as scheduled for revision in recent lifecycle notes. National adoption or withdrawal status can vary by country and catalog. Check the relevant national standards body for the local status if needed.

Q: Is it part of a series?

A: It is classified under ICS 73.060.40 (Aluminium ores) and may be referenced alongside other ISO and national standards on sampling and chemical analysis of aluminium ores (for example sampling standards and related chemical analysis parts adopted nationally). Some countries have published national parts or adoptions that pair ISO 9033 with sampling or analytical series.

Q: What are the key keywords?

A: Aluminium ores; moisture determination; bulk material; drying; sampling; loss on drying; rainfall correction; adhesive samples; Annex A; Annex B.
