DIN EN 207 applies to laser safety spectacles. The LB protection levels from LB1 to LB10 define the power density or energy density that the glasses can withstand for a maximum of 5 seconds or 50 pulses in the case of a direct hit. The values are defined in DIN EN 207, where the LB protection levels can be assigned with the corresponding wavelength and operating mode of the laser.

The standard only applies to eye protection devices for protection against unintentional laser radiation according to DIN EN 60825-1:2007, but not to protective devices against intentional laser beam exposure.

The standard specifies the classification of the light transmission of filters, the refractive index, the material resistance, the covering area, the construction of filters and supporting bodies as well as test methods and marking.

This standard is the selection standard for adjustment safety spectacles. They are only valid in the visible spectral range which is defined by law from
λ=400 - λ=700 nm. The function of goggles is to attenuate the power of the laser beam to a power which is less than one milliwatt [mW]. Powers below one milliwatt for continuous wave lasers are considered to be class 2 lasers and can be classified as safe with the eyelid closure reflex of the human eye. In contrast to DIN EN 60825-4, the standard DIN EN 208 refers to intentional laser beam exposure.

DIN EN 60825-4 specifies the demands on laser safety barriers which enclose the process area of a laser processing machine permanently or temporarily (e.g. for maintenance). It specifies the requirements for laser safety barriers with defined protective function. The scope of the standard includes all components of laser safety shielding, including transparent shields, viewing windows and operating elements.

The specifications of the standard refer to power densities. They specify how the protective properties of a laser safety enclosure can be defined and determined and according to which specifications they must be choosen.

This standard specifies requirements for the function as well as a product marking for temporary and permanent passive protective walls (shielding) for protection against laser radiation.

This standard contains test procedures for the function and the user information to be supplied with the product. The shields are designed to protect the user against:

• unintentional exposure to direct and/or scattered laser radiation;
• temporary laser irradiation based on the functional requirements identified by a risk assessment.

This standard applies to controlled enclosures for installation in workplaces where laser radiation with a maximum of 100 W average power or 30 J single pulse energy within the spectral range of 180 nm (0.18 μm) to 106 nm (1000 μm) is used.

The standard also provides guidance on the selection of such shields.

Laser enclosures and housings supplied as part of the laser device or for mounting on a laser system to form a laser device (according to EN 60825-1) are not considered part of the scope of the standard.

This International Standard is still in progress. It provides guidelines for the application and selection of adequate eye protection. Just like the EN 207 standard, both the filters and the frames must be able to withstand a corresponding laser load for 5 s or 50 pulses. The beam diameter is also 1mm.

The standard specifies the demands for automatic welding filters that switch their light transmission to a preset lower value when a welding arc is ignited (known as welding filters with selectable protection levels). The specifications of this standard apply when such a filter is to be used for continuous observation of the welding process (including gas welding and flame cutting) and also when it is used only during the time when the arc is being ignited. These filters are used in eye protection equipment for welders or are attached to equipment. If they are used in eye protection equipment for welders, further requirements for this type of filter are specified in DIN EN 166.

If they are used in eye protection equipment for welders, further requirements for this type of filter are specified in DIN EN 166.

Attachment A gives a guide for the selection and application of these filters. The specifications for welding filters with switchable light transmission are given in EN 379.

The standard defines protection levels and transmission requirements for protective filters against ultraviolet radiation. The other applicable requirements for these filters and the requirements for the bodies/frames, in which the protective filters are to be installed are specified in EN 166.

Furthermore, the protective filters covered by this standard are not suitable for direct vision into bright light sources such as xenon high-pressure arc lamps or for direct or indirect observation of an arc. For these purposes, a welding protection filter conforming to EN 169 with an appropriate protection level should be used which is suited to the light source being monitored.

This International Standard determines performance requirements for materials, material combinations, and protective clothing with limited flame propagation to limit the possibility of ignition of the clothing and thus becoming a hazard itself. Further requirements for protective clothing are specified, aswell. Protective clothing according to this standard is aimed at protecting workers against accidental and brief contact with small pilot flames in cases where there is no significant heat hazard and no other source of heat is present. If, in addition to protection against the spread of flame, protection against other heat hazards is required, other standards, for example, ISO 11612, are more applicable.

This International Standard defines performance required for protective clothing designed to protect the body (excluding the hands) of individuals against heat and/or flame. The performance requirements of this standard are for clothing requiring limited flame spread, i.e. intended for situations where the wearer is exposed to radiant heat, convective heat or contact heat or splashes of molten metal. The scope of this document covers protective clothing made of flexible materials, such as woven textiles, leather or textiles with metallized coatings. This International Standard does not apply to protective clothing specified in other International Standards, such as welding and related processes.

The American standard ANSI / 136.1-7 contains guidelines for the use of lasers and laser systems. The protective function of laser safety goggles is only required by specifying the optical density (OD) or D () of the laser safety filter.

In contrast to EN 207, no laser exposure tests have to be performed to prove the protective function. Furthermore, no protection levels for filter or frame are required. Laser safety goggles which are only certified according to the American standard ANSI are not approved for use in the EU.

The disregard of European legal requirements can lead to the loss of claims from the statutory accident insurance.

This standard ("IPL standard") lays down essential requirements for eye protectors for intensive light sources (ILS) used by operators using these intensive light sources for medical and cosmetic applications and exposed to excessive optical irradiation in the spectral range between 250 nm and 3 000 nm, excluding laser radiation.

This standard for materials in sheet form used in the manufacture of radiation shielding devices against X-rays of radiation qualities generated by X-ray tube voltages up to 400 kV and against gamma radiation with photon energies up to 1.3 MeV emitted by radionuclides. It lays down the procedures for the determination and indication of the attenuation properties of materials. The attenuation properties are referred to as: -attenuation factor; - build-up factor; - attenuation equivalence, where appropriate accompanied by an indication of homogeneity.

The "PPE Regulation" forms the legal basis for the marketing and provision of PPE products on the internal market. It came into effect on 21.04.2018 with a transitional phase of one year.

The term "PPE" covers any device which is worn or held by a person and which claims to protect that person from a health hazard.

Examples: 

• Safety glasses
• Laser safety goggles and laser safety pads
• Sunglasses, UV protection and IPL protection goggles
• Safety clothing and footwear

Special attention is given to substances which, among other things:

• are carcinogenic (carcinogenic), mutagenic (mutagenic) or reprotoxic (fertility hazardous) (also commonly referred to as CMR substances)
• are not degradable in the environment
• or accumulate in the body

The REACH regulation replaces the following regulations and directives:

• Directive 76/769/EEC
• Directive 91/155/EEC
• Directive 93/67/EEC
• Directive 93/105/EC
• Regulation (EEC) No. 793/93
• Regulation (EC) No. 1488/94
• Directive 2000/21/EC

To implement Directive 2011/65/EU into German law, the Electrical and Electronic Equipment Substances Ordinance was created and thus the requirements of the RoHS Directive were removed from the ElektroG.

Some of the substances used in electrical engineering are regarded as environmentally hazardous.

On the one hand, they are toxic when used in certain quantities, and on the other hand they cannot be broken down by the environment or can only be broken down with difficulty, e.g: lead >0.1%, mercury >0.1%, cadmium >0.1%, hexavalent chromium >0.1%

Polybrominated biphenyls (PBB) >0.1% and polybrominated diphenyl ethers (PBDE) >0.1%.
