Question 13

Describe the scope of eye protectors (BS EN 166)?

Answer 13

• Applies to all eye protectors used against various hazards which are likely to damage eye or impair vision in:
  o Industry; Laboratories
  o Educational establishments
  o Home
• Includes those fitted with Rx lenses.
• Does not protect against gamma and X-ray, laser beams, infrared radiation emitted by low-temperature sources.
• Excludes eye protectors for which separate and complete standards exist. Laser eye protectors, sunglasses for general use

Question 14

Describe BS EN 166?

Answer 14

• BS EN 166: BS 2092, deals with general considerations relating to eye protectors, namely:
  o Designation
  o Classification
  o Basic requirements
  o Particular requirements
  o Testing and applications
  o Marking
• The marking of oculars should contain info: the ocular marking may include a certification mark and a mark to assist correct fitting of laminated oculars

Question 15

Describe filters for eye protection?

Answer 15

• Transmittance characteristics are given by the scale number.
  o Scale number is a combination of the code number and shade number (1-16), joined together by a dash.
• For welding filters only, the shade number is given

Question 16

Describe the factors for the identification of the manufacturer?

Answer 16

• Optical class:
  o Indicates measure of optical tolerance to which the lenses have been manufactured.
  o One of the 3 optical classes should be included, except in the case of cover plates, which are always required to be class 1.
• Mechanical strength:
  o Symbols relating to oculars, which withstand one of the various mechanical strength tests, should be included.
• Non-adherence of molten metal and resistance to penetration of hot solids should be marked by 9.
• Resistance to short circuit electric arc should be marked with the number 8.
• Resistance to non-adherence of molten metal and resistance to penetration of hot solids should be marked by 9.
• Resistance to surface damage by fine particles should be marked by K. Resistance to fogging should be marked by N.

Question 17

Describe oculars?

Answer 17

• Original/replacement oculars:
  o To identify if an ocular is an original or a replacement, the manufacturer may use the symbols ‘O’ (original) or ‘V’ (replacement).
• Resistance to high-speed particles at extremes of temperature should be marked with one of the impact symbols followed by the letter “T”. i.e. FT, BT or AT.

Question 18

Describe the marking of eye protectors where frame & ocular form a single unit?

Answer 18

• Eye protectors in which frame and ocular form a single unit shall be marked on the frame.
• Marking must comprise full ocular marking, a hyphen, the number of this standard and then any appropriate symbols for field of use and level of impact.
• A standard specifies what info should be supplied to the user by the manufacturer for example, instructions on field of use, storage, maintenance etc.
• e.g.: Single unit eye-protector with IR filter effect resistant to low energy impact, resistant to adherence of molten metal and penetration of hot solids, with the frame offering protection against liquids, molten metals and hot solids and being resistant to low energy impact
