What is the current standards for curved(bent) glass? Either british/european or otherwise?
Depending on the application where the bent tempered glazing is used at least these standards apply:
ECE Regulation 43 (annex 4 and 5)
JAPAN Safety Regulations for Road Vehicles, Article 29
USA FMVSS 205 / ANSI Z26.1-1977 Z26.1a-1980
ISO has also documented several inspection methods and standards for different glazing products such as:
ISO 9050:2003 Glass in building -- Determination of light transmittance, solar direct transmittance, total solar energy transmittance, ultraviolet transmittance and related glazing factors
ISO 3537:1999
Road vehicles -- Safety glazing materials -- Mechanical tests
And
ISO/TS 16949:2009, Quality management systems – Particular requirements for the application of ISO 9001:2008 for automotive production and relevant service part organizations
Hope this answers your question!
