TS EN ISO 374-1/A1

TS EN ISO 374-1/A1 is Amendment 1 to the standard for protective gloves against dangerous chemicals and micro-organisms, specifically the part that defines terminology and performance requirements for chemical risks. As an amendment, it updates the parent standard rather than standing alone as a complete product standard, so it should be read as part of the broader framework used to describe and assess chemical protective gloves.

What chemical-protective glove terminology is meant to organise

In general technical terms, chemical protective gloves are not judged only by overall toughness. Their function depends on how the glove material behaves when exposed to chemicals: whether the material resists degradation, whether liquid or vapour can pass through it, and whether the glove remains structurally sound during use. Standards in the ISO 374 family create a shared technical language for these ideas so that glove performance claims can be understood consistently across manufacturers and users.

Because this is an amendment, it should be understood as a document that refines or updates the parent standard’s terminology or performance-related wording, rather than a separate, complete specification with independently verifiable requirements. In practical product documentation, such amendments matter because they can affect how glove resistance claims, classification terms, or related markings are interpreted. The exact change introduced by this amendment is not recoverable from the available record, so only the general technical context can be stated here.

• Chemical glove selection depends on the substance involved and the expected contact conditions.
• Barrier performance is commonly discussed in terms of permeation, penetration, and material degradation.
• A terminology-focused standard helps align manufacturer claims with user understanding.
• An amendment is read together with the base standard it revises.
