ČSN EN 16307-5 This document specifies requirements for the types of industrial trucks specified in the scope of EN ISO 3691 5:20151. This document is intended to be used in conjunction with EN ISO 3691 5:20151. This document deals with the following significant hazards, hazardous situations or hazardous events relevant to pedestrian-propelled trucks, when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer: - protection against crushing, shearing and trapping; - electrical requirements; - electromagnetic immunity. These requirements are supplementary to those stated in EN ISO 3691 5:20151 with the addition of requirements for the following hazard: - electromagnetic immunity (external radiation). This document partially replaces the following requirement of EN ISO 3691 5:20151: - electrical requirements. This document specifies supplementary requirements to EN ISO 3691 5:20151: - protection against crushing, shearing and trapping; - information for use (instruction handbook and marking). This document does not specify supplementary requirements to EN ISO 3691 5:20151: - static electricity; - radiation; - general principles for the drafting of instructions; - sales literature. Annex A (informative) contains the list of significant hazards covered by this document.

ČSN EN 9163 This document provides a harmonized process and documentation requirements for the establishment of CoCs used to attest the conformity of aviation, space, and defence products (e.g., assemblies, sub-assemblies, equipment and systems, parts, material, software) or services. It includes a CoC template and supporting instructions on how to complete it. When quoted by the customer in a contractual requirement, application of this document is mandatory. In other cases, its use is recommended, but if there is a conflict between the requirements of this document and customer or applicable statutory/regulatory requirements, the latter shall take precedence. This document can be used by other industries that require the use/application of a CoC. Requirements for the establishment of Authorized Release Certificates (ARCs) [e.g., European Union Aviation Safety Agency (EASA) Form 1, Federal Aviation Administration (FAA) 8130-3 tag, Civil Aviation Administration of China (CAAC) Form 038] by an external provider holding a production approval (for new aviation products, production, or spares) or maintenance approval (i.e., for in service repairs, modifications, after sales maintenance, overhaul activities, inspections) are not covered by this document, as applicable rules are defined by the aviation authorities having granted these approvals.

ČSN EN 2267-012 This document specifies the characteristics of UV laser printable electrical wires DZ family for use in the on board: - 115 VAC (phase to neutral) or 200 VAC (phase to phase) electrical network of aircraft; - 230 VAC (phase to neutral) or 400 VAC (phase to phase) electrical network of aircraft and particularly use in non-pressurized areas. This cable family is used at operating temperature between -65 °C and 260 °C. These cables are demonstrated to be arc resistant for both networks (115 VAC and 230 VAC).

ČSN EN 3774-006 This document specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between -55 °C and 125 °C for ratings 15 A and at an altitude of 15 000 m max. These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping. They will continue to function up to the short-circuit current.

ČSN EN 2995-006 This document specifies the characteristics of single-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between -55 °C and 125 °C and at an altitude of 15 000 m max. These circuit breakers are operated by a push-pull type single push button (actuator), with delayed action "trip-free" tripping with a polarized signal contact which is open when main contacts are closed, and inversely. They will continue to function up to the short-circuit current.
