ISO 3977

Image
  Design and procurement standards for gas turbine system applications ISO 3977  was created by Technical Committee TC 192, Gas turbines. All different parts of ISO 3977 define a standard framework for dealing with questions of fuel and other matters, such as the minimum information to be provided by both the purchaser and the manufacturer. Attention is drawn to the need for technical consultation between the manufacturer and the purchaser to ensure compatibility of equipment being supplied, particularly where the responsibility for supply is divided. It is applicable to open-cycle gas turbine power plant using combustion systems, and to closed-cycle, semi closed-cycle and combined-cycle gas turbine power plants. In the case of turbines using free piston gas generators or special heat sources, it may be used as a basis but will need to be suitably modified. ISO 3977 consists of the following parts, under the general title: Gas turbines — Procurement Part 1: ISO 3977-1:1997(EN) Gas turb

  Agricultural Tractors — Rear-mounted power take-off types 1, 2, 3, and 4 Part 1: General specifications, safety requirements, dimensions for master shield and clearance zone. ISO 500-1:2014 (EN) was created by ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors was created by ISO/TC 23, Tractors and machinery for agriculture. And forestry, Subcommittee SC 4, Tractors ISO 500:2004 specifies the general specifications, including speeds, safety requirements, the dimensions for the master shield. And clearance zones for rear-mounted power take-offs (PTOs) of types 1, 2, 3, and 4 on agricultural tractors with a track setting of more than 1 150 mm, those with track setting width of 1 150 mm or less are covered in ISO 500-2 In addition, This second revision of ISO 500-1:2014 (EN) was created by ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors canceled and replaced the first edition (ISO 500-1). Of which it co

  Graphical symbols — Safety colors and safety signs Part 1: Design principles for safety signs and safety markings ISO 3864 was created by Technical Committee ISO/TC 145, Graphical symbols, Subcommittee SC 2, Safety identification, signs, shapes, symbols, and colors. ISO 3864-1:2011(EN) together with ISO 3864-4, cancels and replaces ISO 3864-1:2002, which has been technically revised. The ISO 3864 consists of the following parts, under the general title Graphical symbols — Safety colors and safety signs: Part 1: ISO 3864-1:2011(EN) Graphical symbols — Safety colors and safety signs — Part 1: Design principles for safety signs and safety markings ISO 3864-1:2011 defines the safety identification colors and design principles for safety signs and safety markings to be used in workplaces and in public areas. For the purpose of accident prevention, fire protection, health hazard information. And emergency evacuation. It also establishes the basic principles to be applied when developing st

  What is ISO 3055:2021 Kitchen equipment — Coordinating sizes? ISO 3055:2021 pertains to coordinating sizes for kitchen equipment. This standard provides guidelines for manufacturers and designers of kitchen equipment to ensure that their products are of a consistent size and can be easily coordinated with other kitchen equipment. This standard specifies the basic sizes for kitchen equipment such as ovens, ranges, refrigerators, and dishwashers, among others. It also provides recommendations for the placement of electrical and water connections to ensure that they are easily accessible and consistent across different brands and models of kitchen equipment. The purpose of this standard is to improve the compatibility and interoperability of kitchen equipment from different manufacturers, which can help reduce installation costs, improve efficiency, and simplify maintenance and repairs. ISO 3055helps to promote standardization and consistency in the design and manufacture of kitchen equ

  What is EN 352-2:2021 – Hearing protectors – General requirements – Part 2: Earplugs ? EN 352-2:2021 specifies the general requirements for earplugs as personal protective equipment for hearing protection. It is part of a series of standards that provide guidance on hearing protectors and their use in different occupational environments. EN 352-2 specifically covers earplugs, which are designed to be inserted into the ear canal to reduce the amount of sound that reaches the eardrum. The standard specifies the minimum requirements for design, construction, performance, and labeling of earplugs intended for use in noisy environments. It also provides guidelines for testing and evaluating the effectiveness of earplugs in reducing noise levels. Therefore, It applies to all earplugs regardless of their shape, size, or intended use, and is applicable to both reusable and disposable earplugs. It is intended to ensure that earplugs meet certain safety and performance criteria. And that they
