Does this standard specify the impact resistance for a helmet?

No, this standard gives general requirements for all PPE. Specific performance like impact resistance is in the relevant product standard, such as IS 2925 for safety helmets.

What does 'innocuousness' mean in this standard?

It means the PPE itself must not cause harm to the user, like skin irritation or allergic reactions. It places limits on harmful substances like pH and hexavalent chromium (Clause 4.2).

Is marking on PPE mandatory according to this code?

Yes, Clause 5 requires PPE to be marked with information like the manufacturer's name, product identification, and reference to the specific IS standard it complies with.

This standard (Part 1) specifies general performance requirements for ergonomics, innocuousness, sizing, marking, and information to be supplied by the manufacturer for all types of personal protective equipment (PPE). It is a foundational document intended to be used in conjunction with specific standards for particular PPE products.

Lays down general requirements for the design, performance, marking, and testing of personal protective equipment.

Quick Reference Values

pH of materials in contact with skinMust be between 3.5 and 9.5

Maximum hexavalent chromium in leather components< 3.0 mg/kg

Water vapour resistanceShould be as low as possible for comfort

Minimum height of pictogram on marking10 mm

Release of nickel from metallic parts in prolonged skin contact< 0.5 µg/cm²/week

Practical Notes

This is a horizontal standard; its requirements apply to all PPE unless overridden by a specific product standard (e.g., IS 2925 for safety helmets).

It focuses on user safety from the PPE material itself (e.g., skin irritation, allergies) and usability, not the specific hazard the PPE protects against.

Always check for the IS marking and review the manufacturer's information leaflet, which is a mandatory requirement under this standard.
