TS ISO 9802/Cor 1

TS ISO 9802/Cor 1 is a corrigendum to ISO 9802:1996 for the vocabulary of raw optical glass. A corrigendum is used to clarify terminology or correct minor editorial issues in the parent standard; it does not, by itself, establish a new test method or product specification. In practical terms, this document supports the consistent naming of raw optical glass concepts used in production, purchasing, quality control, and technical communication.

Why vocabulary matters in optical glass

Raw optical glass is the glass material prepared for optical applications before it becomes a finished component. In this field, vocabulary helps distinguish terms such as composition, transparency, refractive index, dispersion, homogeneity, and defect types. Clear terminology reduces ambiguity when manufacturers, laboratories, and customers discuss material characteristics or compare different glass families. Vocabulary standards are especially useful where small differences in wording can change the technical meaning of a specification.

What this correction record means in practice

• It supports consistency in the terminology used by the parent standard.
• It does not introduce a new test method, specimen preparation rule, or performance limit.
• It helps readers interpret optical glass, glass-industry, and raw-material terms within the same technical context.
• As a withdrawn record, it remains important for historical reference and archive use.
