Thermal performance of windows, doors and shutters. Determination of thermal transmittance by hot box method - Frames

ISO 9628 provides guidance on characteristics

BS EN IEC 62149‑11 gives you performance standards for photonic chip-scale packages and tests to interface them with multimode fibres

Determination of scratch resistance:

[IEC 62888‑3:2018

lower packaging and deployment complexity

5 mm2 and has been limited to 1 200 mm2 for connectors for copper and aluminium conductors because test experience and applications are rare for conductors of larger cross-sectional areas

Such standard procedures are provided in ISO 23611-1 to ISO 23611-6

This standard gives guidance on these measures
