T/SDHA 101-2018 Environmental Label Product Technical Requirements for Wooden Mechanical Clocks

Scope

Scope: This standard specifies the terms and definitions, basic requirements, technical content, and testing methods for environmentally friendly labeled products of wooden-case mechanical clocks. This standard applies to all types of wooden-case mechanical clocks. Main technical content: With people's increasing demands for the environment in daily life and higher limits on harmful substances in indoor items, this standard proposes the limits on harmful substances and testing methods that meet the technical requirements for national environmental labeling products. It distinguishes products that use low-quality and cheap materials and exceed the limits on harmful substances, which endanger human health, in order to protect the environment, safeguard consumers' legitimate rights and interests, and promote the healthy development of the watch and clock industry. This standard specifies the limits on harmful substances and testing methods for wooden-case mechanical clocks. This standard applies to wooden-case mechanical clocks with metal-made mechanical clock movements and solid wooden clock cases. During the development of this standard, the following aspects were given priority consideration: a) Purpose and application: The purpose of this standard is to detect the limits on harmful substances in products without damaging the finished sample. b) Experimental instruments and equipment: This standard provides the names, resolutions, and maximum allowable errors of the instruments and equipment used for testing, and gives an equivalent method for detecting formaldehyde content using the 1m climate chamber method.
