What is ISO 23512 about?  
ISO 23512 specifies the minimum essential variables in order to produce a component of the required consistency and quality for the following thermal joining processes:
- Ultrasonic welding/staking/spot welding
- Infrared welding
- Hot gas convection welding
- Linear vibration welding
- Orbital vibration welding
- Spin welding
- Laser welding
- Hot plate welding
- Heat staking: hot air
- Heat staking: electrical
- Heat staking: infrared (IR).
Note: Standards on joining of plastic pipes, fittings, valves and/or auxiliary equipment, and the assessment of the properties of the resulting joints are developed and maintained by ISO/TC 138. 
Who is ISO 23512 for? 
ISO 23512 on joining of thermoplastic moulded components is relevant to: 
- Plastic and polymer manufacturers
- Plastic industry
- Polymer scientists
- Plastic/polymer testing laboratories
- Chemical engineers  
Why should you use ISO 23512?  
ISO 23512 has been developed to help organizations better understand and implement controls with thermal joining processes through the use of thermal joining process specifications.
ISO 23512 defines the thermal joining process specification (TJPS) for each of the thermal joining processes listed above, to ensure that all the essential variables are properly considered, including the qualified range of each variable, in order to establish and maintain component quality at an acceptable level.
A TJPS shall provide the minimum information as suggested under ISO 23512, required to make a joint of acceptable quality, as part of the component manufacturing quality agreement between the joining organization and the customer.
