Requirements for certification and assessment of infrared thermography personnel in condition monitoring per ISO 29821 Introduction to ISO 29821 ISO 29821 specifies the qualification requirements and assessment methods for personnel performing infrared thermography for condition monitoring and diagnostics of machinery,…

Complete Guide to ISO_29783-2 A lower limb prosthesis must withstand 2–3 million loading cycles over its typical 3–5 year service life — equivalent to walking from London to Moscow and back. ISO 29783-2 ensures this fatigue endurance through standardised testing.…

Complete Guide to ISO_29783-3 Upper limb prostheses face a unique challenge: they must be lightweight enough for comfortable daily wear yet strong enough to handle loads ranging from a 0.5 kg coffee cup to a 20 kg suitcase. ISO 29783-3…

A comprehensive technical guide to ISO 29802 standards for virtualization platform design, resource scheduling, security isolation, and performance benchmarking. Introduction to ISO 29802: Virtualization Platform Architecture ISO 29802 establishes a comprehensive framework for virtualization platforms in modern information technology infrastructure.…

Material selection, control, environmental durability and safety for space hardware Material selection for spacecraft involves evaluating over 200 distinct properties including mechanical, thermal, electrical, outgassing, radiation resistance, and atomic oxygen erosion yield. A single wrong choice can lead to catastrophic…

Complete Guide to ISO_29781 Sealant adhesion failure is responsible for approximately 70 % of all building facade water ingress complaints. Proper adhesion testing per ISO 29781 can reduce this risk by an order of magnitude. 1. Scope and Principles of…

Complete Guide to ISO_29782 While adhesion fails at the interface, cohesion failure occurs within the sealant itself — and it is the sealant’s cohesive strength that ultimately determines joint movement capacity. 1. Cohesion: The Internal Strength of Sealants ISO 29782…

Complete Guide to ISO_29783-1 Standardised terminology is the foundation of effective communication in prosthetic engineering. ISO 29783-1 defines over 200 terms that eliminate ambiguity in clinical, technical, and regulatory contexts. 1. Structural Vocabulary: Components and Interfaces ISO 29783-1 establishes a…

Structural engineering requirements for space vehicle primary and secondary structures The primary structure of a spacecraft typically represents 18–25% of the total launch mass. Every kilogram of structure saved translates directly into increased payload mass or reduced propellant requirements for…

Design, tribology, actuation and reliability of space mechanisms Space mechanisms are the most failure-prone subsystem on spacecraft, accounting for approximately 20–25% of all in-orbit anomalies. A single stuck mechanism can render a multi-billion dollar mission completely useless. 1. Mechanism Classification…

Selection, qualification, procurement and management of electrical electronic and electromechanical parts for spacecraft EEE Parts (Electrical, Electronic and Electromechanical components) account for 60–80% of all spacecraft anomalies. A single counterfeit part or latent manufacturing defect can compromise a mission costing…

ISO Standard — Space systems — Thermal control — Engineering Technical Article 1. Overview of ISO 29764 ISO 29764 defines thermal control requirements for space systems, covering passive and active thermal management, material thermophysical properties, analysis verification, and acceptance testing.…

ISO Standard — Space systems — Propellant systems — Engineering Technical Article 1. Overview of ISO 29765 ISO 29765 specifies safety and performance requirements for propellant systems in space applications, including liquid and solid propellant handling, storage, transfer, and compatibility…

Engineering design principles for passive and active thermal control subsystems Thermal control is the single largest mass contributor to spacecraft after the primary structure. A 1 kg saving in thermal hardware can reduce launch cost by approximately USD 10,000–20,000 depending…

Design, qualification, and performance characterisation of space solar array systems Solar arrays are the most cost-effective power source for the vast majority of space missions. Modern triple-junction (3J) InGaP/InGaAs/Ge cells achieve beginning-of-life (BOL) efficiencies exceeding 32% under AM0 illumination —…
