BS ISO Standards Single-File Series Overview · Batch 17 — A Compilation of 150 International Standards (ISO) and Their Technical Points

The BS ISO series comprises British National Standards published by the British Standards Institution (BSI) as the UK implementation of International Standards developed by the International Organization for Standardization (ISO). This batch (Batch 17) consists of 150 single-file standards drawn from the BS ISO series, spanning photocatalytic materials, mobile robots, financial services (GP core principles conformance assessment), space data and information transfer security, building sealants, fire safety, water and soil quality, and traditional Chinese medicine.

Most of these standards adopt ISO International Standards identically and cover test methods, product specifications, terminology, safety requirements and management guidelines. The article lists the full standard set in numerical order and expands on five representative standards, helping readers understand the structure, technical requirements and application points of BS ISO single-file standards.

1. Series Overview 📌

This batch is arranged by standard number from ISO 19635 to ISO 21398 and covers photocatalytic materials (antialgal activity, photocatalytic activity by dissolved oxygen consumption, antimicrobial/antiviral activity under indoor and outdoor lighting), mobile robots (vocabulary, performance tests), fertilizers (solid urea aldehyde slow release fertilizer, HPLC determination of urea), financial services (GP core principles conformance assessment, common financial industry message scheme, payment card industry data security), space data link security (space data link security protocol, bundle protocol, free-space laser communication), building sealants (curing behaviour, durability to extension compression cycling, tear resistance), fire safety (sampling and analysis of fire effluents, toxic gas species yields, assessment of fire threat to people), and water quality (acute toxicity to marine and freshwater rotifers), soil (ammonium nitrate extraction of trace elements, urea content).

By standard type, numerous test methods and analysis standards are present together with product specifications, terminology and design guideline standards. The space data and information transfer security group forms an inter-satellite and space-ground communication security system from the bundle protocol to the space data link security protocol; the fire safety group covers fire effluent sampling, toxic gas analysis and assessment of fire threat to people.

3. Key Technical Requirements 🔧

For photocatalytic materials, ISO 19635 specifies antialgal activity testing, ISO 19722 specifies photocatalytic activity by dissolved oxygen consumption, and ISO 20185 specifies antimicrobial activity under indoor lighting, forming with the antiviral activity tests a functional evaluation system for photocatalytic materials.

For space data and information transfer security, ISO 21324 specifies the space data link security protocol, and ISO 21323 specifies the bundle protocol (delay-tolerant networking, DTN), providing the security and networking foundation for inter-satellite and space-ground communication.

For financial services, the ISO 20022 series specifies the common financial industry message scheme, the ISO 20304 series specifies payment card industry data security technical controls in SaaS environments, and ISO 20122/20123 specify security audit procedures, forming the financial messaging and payment security standard system.

For building sealants, ISO 19861 specifies curing behaviour, ISO 19862 specifies durability to extension compression cycling under accelerated weathering, and ISO 19863 specifies tear resistance, used for performance evaluation of joint sealing materials.

For fire safety, ISO 19701 specifies sampling and analysis of fire effluents, ISO 19703 specifies toxic gas species yields calculation, and ISO 19706 specifies guidelines for assessing the fire threat to people, forming a fire hazard evaluation system.

4. Technical Interpretation of Representative Standards 🔍

BS ISO 21324:2016 — Space Data Link Security Protocol

Scope: specifies the security protocol for space data links in space data and information transfer systems.

Points: specifies authentication and encryption mechanisms for the TC, TM and AOS space links, key management, anti-replay and integrity protection requirements, providing end-to-end security services for space-ground links and forming an important foundation for spacecraft data security.

BS ISO 19649:2017 — Mobile Robots Vocabulary

Scope: specifies general terminology and definitions for mobile robots.

Points: defines core concepts such as mobile robot, autonomous mobility, localization, navigation and obstacle avoidance, providing a common language for mobile robot design and evaluation, and forming with the ISO 18646 series performance standards the mobile robot standard system.

BS ISO 19706:2011 — Guidelines for Assessing the Fire Threat to People

Scope: provides guidelines for assessing the threat to people from outdoor and indoor fires.

Points: specifies assessment methods and input data for fire products, heat exposure and human tolerance limits (heat, visibility, toxicity), supporting life safety assessment in performance-based fire design.

BS ISO 20345:2011 — Personal Protective Equipment Safety Footwear

Scope: specifies basic requirements and test methods for safety footwear.

Points: specifies impact and compression resistance of the protective toe cap, slip resistance, puncture resistance and durability requirements, together with corresponding test methods, forming the basis for certification and selection of industrial safety footwear.

BS ISO 21013-1:2016 — Pressure-relief Devices for Cryogenic Service

Scope: specifies requirements for reclosing pressure-relief valves for cryogenic service.

Points: specifies structure, materials, set pressure and flow characteristics, and test requirements of cryogenic relief valves, ensuring overpressure protection safety of cryogenic storage and transport equipment.

5. Engineering Practice and Applications 🛠️

Space organisations should implement the bundle protocol and space data link security in accordance with ISO 21323/21324, ensuring inter-satellite and space-ground communication security.

Financial enterprises should implement the unified message scheme in accordance with the ISO 20022 series and ensure payment security in accordance with ISO 20304/20122/20123.

Construction and building material enterprises should evaluate joint sealants in accordance with ISO 19861-19863, ensuring waterproof durability of curtain walls and building joints.

Fire and safety engineers should conduct fire hazard evaluation in accordance with ISO 19701/19703/19706 and select protective footwear conforming to ISO 20345/20347.
