DIRECT ANSWERImpact-test need and temperature follow material specification and edition, thickness, supply condition, minimum design metal temperature, joint details, heat treatment and approved exemptions.
Impact-test basis
- Material grade, product form and thickness
- Minimum design metal temperature
- Heat treatment and welded-joint condition
- Test temperature, specimens, acceptance and exemptions
Relevant manufacturing capability
- Drawing, datasheet and equipment-list manufacturability review
- Self-manufactured and coordinated-supply scope identification
- Technical, quality, document and delivery clarification
Key notes
- Do not infer impact testing solely from ambient temperature or equipment name.
