This standard replaces LY/T 1187-2006 "chain saw chain". Compared with LY/T 1187-2006, the main technical changes are as follows. a) Revised the name of the standard and changed the “chain saw chain” to “forestry chain saw chain”; b) revised normative references (see Chapter 2, Chapter 2 of the.2006 edition); c) increased the term and definition of “sharp hold period” (see Chapter 3); d) modified the method of specifying the model of the saw chain (see 4.1,.2006 edition 3.1); e) removed the material requirements for the saw chain (2006 edition 4.1); f) modified the chain limit parameter (see 4.2,.2006 edition 3.2); g) added to the tolerance requirements that “the dimensional tolerances of the saw chain are to comply with the manufacturer's drawings and the relevant technical agreements” (see 5.2.1), Increased tolerance inspection methods (see 5.2.2); h) adding “coating or strengthening layer thickness using a coating thickness gauge” in the hardness test method (see 5.3.2); i) modified the requirements for static breaking force (see 5.4.1,.2006 edition 4.6); j) modified the requirements for deflection (see 5.5.1,.2006 edition 4.7); k) revised the requirements for the limit of material (see 5.6.1,.2006 edition 4.8); l) increased requirements and test methods for sawing efficiency (see 5.7); m) increase the requirements and test methods for sharp retention periods (see 5.8); n) modified service life requirements and test methods (see 5.9,.2006 editions 4.12 and 5.6); o) increased durability requirements and test methods (see 5.10); p) an inspection method that increases the quality of appearance (see 5.11.2); q) Revised the inspection rules and divided the product inspection into factory inspection, type inspection and third party inspection (see Chapter 6,.2006 edition) Chapter 6).

Forestry machinery chain saw chain1 ScopeThis standard specifies the terms, definitions, models, specifications, technical requirements, test methods, inspection rules, marking, packaging, transportation and Storage. This standard applies to chain saws for chain saws and hand-held electric chain saws.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 191 packaging storage and transportation icon GB/T 230.1 Rockwell hardness test for metallic materials - Part 1. Test methods (A, B, C, D, E, F, G, H, K, N, T ruler) GB/T 1804 General tolerances tolerances for linear and angular dimensions of tolerances GB/T 2828.4 Test procedures for counting sampling - Part 4. Procedures for assessing quality levels GB/T 5849 Blockboard General technical conditions for GB/T 13384 mechanical and electrical product packaging GB/T 18516 portable chainsaw sawing efficiency and fuel consumption rate test method engineering method3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Sharp retention period sharpretentionperiod The new saw chain starts from continuous sawing and meets the test wood specified in 5.9.2 (hereinafter referred to as the test material) until the cutting efficiency is reduced to a new one. Cumulative sawing time up to 40% of the state. Note 1. This parameter mainly reflects the ability of the saw chain to remain sharp. Note 2. See GB/T 18516 for the sawing conditions and methods of the saw chain.4 Models and specifications4.1 The model of the saw chain includes the pitch code, the drive chain thickness code, the tooth shape code, the pitch arrangement tightness code, and the anti-rebound code. And the number of transmission chains. The model of the saw chain is based on the pitch, and some other parameters or feature codes of the five aspects can be omitted. Specific model The regulations are shown in Table 1. The four arrangements of the pitch are shown in Figure 1. The model representation is as follows. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of LY/T 1187-2016_English be delivered?Answer: Upon your order, we will start to translate LY/T 1187-2016_English as soon as possible, and keep you informed of the progress.
