BS ISO TS — International Technical Specifications Single-File Series Overview (5 Standards)
Covers ISO/TS technical specifications on metalworking lubricants, temporary corrosion-protection oils, electromagnetic current meters, and natural gas odorizing
📐 The BS ISO/TS series comprises ISO Technical Specifications (TS) adopted in the UK as British Standards. A technical specification is the type of ISO publication used when a document is not yet suitable for issue as a full International Standard, providing guidance or provisional requirements for a specific technical field. The five standards covered here address lubricant specification guidance, open-channel velocity measurement and natural gas odorizing, illustrating the use of ISO/TS in industrial fluids, hydrometry and energy gases.
Technical Specifications (TS) are provisional and advisory in nature: although reviewed by ISO technical committees, they do not have the status of full International Standards, and users should watch for later upgrade or revision.
1. Standard List and System Framework
The five BS ISO/TS standards covered in this overview are listed below, addressing industrial lubricants (class L), hydrometric velocity measurement and natural gas analysis.

2. Technical Content of Representative Standards

BS ISO/TS 12927:1999 — Guidelines for establishing specifications for metalworking lubricants (class L, Family M)
This standard provides guidance for establishing specifications for products in Family M (Metalworking) of lubricants, industrial oils and related products (class L). Metalworking fluids are used in cutting, grinding and forming processes and vary widely in type and performance requirements. The standard gives the structure of a specification, an explanation of the symbols used, and a non-exhaustive list of characteristics needed to establish specifications. The characteristics cover lubricity, cooling, corrosion protection, anti-corrosion, stability, foam and microbiology; users select appropriate items according to the machining method and conditions. Annex A gives information on the anti-corrosive properties of water-miscible machining fluids in contact with non-ferrous metals, for the reference of specification writers.
S
BS ISO/TS 12928:1999 — Guidelines for establishing specifications for temporary corrosion-protection products (class L, Family R)
This standard provides guidance for establishing specifications for Family R (products for temporary protection against corrosion, such as rust-preventive oils and greases) of class L. These products protect metal parts during storage, transport and machining intervals. The standard gives the structure of a specification and the list of required characteristics, including corrosion-protection performance, film thickness and film properties, and compatibility with wet skin-pass products. Annex A addresses compatibility with wet skin-pass products, and Annex B describes a long-duration cyclic staining test used to evaluate rust-preventive oil performance under specific conditions.
S
BS ISO/TS 15768:2000 — Design, selection and use of electromagnetic current meters
This standard specifies the design, selection and use of electromagnetic current meters for measuring liquid velocity in open channels. These meters measure the electromotive force induced by the water flow cutting a magnetic field, and suit flows carrying sediment, fibres or corrosive matter, as well as stations requiring continuous automatic recording. The standard gives the physical characteristics of the sensing head, the measurement principle, calibration methods, installation requirements and guidance on use, and specifies the units and terminology of velocity measurement. Compared with rotor-type current meters, electromagnetic meters have no moving parts, resist wear and suit long-term on-line measurement, making them important instruments in hydrological networks and flow-metering systems.

BS ISO/TS 16922:2002 — Guidelines for odorizing natural gas
This standard provides guidelines for odorizing natural gas. Odorizing adds a substance with a detectable odour (an odorant) to odourless or weakly odorous gas so that leaks can be noticed, protecting users. The standard covers odorant selection, odorization concentration, odorizing system design and operation, odorant detection and safety requirements. Odorants are typically mercaptans or sulphur compounds, and their concentration should ensure that the odour is perceptible to an ordinary person before the gas reaches the lower explosive limit. The standard is aimed at gas supply companies, odorizing equipment manufacturers and safety regulators, and is an important technical basis for the safe operation of town gas.

BS ISO/TS 16799:1999 — (Scan version)
⚠️ Scan-only; written from public-domain knowledge. BS ISO/TS 16799:1999 exists in the repository only as a scanned copy with no readable text. Based on the ISO/TS technical specification numbering, it belongs to the ISO/TS series and concerns guidance in a specific technical field. Since the original text cannot be read, this overview makes no inference about its specific clauses; it is listed in the standard table, and readers should refer to the official BSI publication for any specific application.
3. Key Technical Points
The key technical points of the BS ISO/TS series can be summarized as follows:
| Reference | Title |
|---|---|
| 规范制定指南 | Guidance for the structure, symbols and characteristic lists of specifications for metalworking fluids and rust-preventive products |
| 加工液特性 | Lubricity, cooling, corrosion protection, anti-corrosion, stability, foam and microbiology characteristics |
| 电磁流速仪 | No moving parts; measures velocity via induced EMF; suits sediment/fibre-laden flow and continuous on-line measurement |
| 加臭安全 | Odorant concentration should make gas perceptible before reaching the lower explosive limit |
These technical specifications illustrate ISO’s flexible publication strategy in fields “still requiring practical validation”: guidance is first issued as a TS, then upgraded to a full standard once the technology matures and experience accumulates.
4. Engineering Practice and Application
🛠️ Metalworking and rust prevention: BS ISO/TS 12927/12928 guide manufacturers and users in establishing technical specifications for metalworking fluids and rust-preventive oils, used for procurement acceptance and quality evaluation across mechanical, automotive and steel industries.
🌊 Hydrometry: BS ISO/TS 15768 supports the selection, installation and calibration of electromagnetic current meters for open-channel flow metering, serving hydrological networks, irrigation metering and environmental monitoring.
🔥 Gas safety: BS ISO/TS 16922 supports the design and operational management of natural gas odorizing systems, an important reference for safe town-gas supply.
5. FAQ
Q: Q: How does an ISO Technical Specification (TS) differ from an International Standard?
A: A: A TS is the ISO publication type used when the technology is still developing or not yet ready for a full standard. It is reviewed by the technical committee but does not follow the full International Standard procedure; it is advisory and provisional, and is periodically reviewed to decide whether to be upgraded to a full standard or withdrawn.

Q: Q: Why do metalworking fluid specifications need guidance?
A: A: Metalworking fluids vary widely, and their lubricity, cooling, corrosion protection, anti-corrosion and stability depend on the machining method, workpiece material and conditions. The guidance provides a common specification structure and characteristic list so that different manufacturers and users can evaluate and compare products within the same framework.

Q: Q: Where are electromagnetic current meters suitable?
A: A: They suit flows carrying sediment, fibres or corrosive matter, and stations requiring long-term continuous automatic recording. They have no moving parts and resist wear, but require external power and associated electronics, with higher installation and calibration requirements.

Q: Q: Why is natural gas odorized?
A: A: Natural gas is essentially odourless, so leaks are hard to detect, creating explosion and poisoning risks. Adding an odorant makes leaks noticeable before reaching dangerous concentrations, alerting users to act in time.
